Principal Examiners have been involved in all aspects of this book to ensure that the content gives the best possible match to both the syllabus and to the type of questions asked in the examination. The book is arranged in two sections. Chapters 18—30 correspond to the A level section of the course for examinations in papers 4 and 5.

Within each of these sections the material is arranged in the same sequence as the syllabus. For example in the AS section, Chapter 1 deals with atoms, molecules and stoichiometry and Chapter 2 deals with atomic structure.

The A level section starts with lattice energy Chapter syllabus section 5 then progresses to redox potentials Chapter syllabus section 6. Nearly all the written material is new, although some of the diagrams have been based on material from the endorsed Chemistry for OCR books 1 and 2 Acaster and Ryan, There are separate chapters about nitrogen and sulfur Chapter 12 and the elements and compounds of Group IV Chapter 22 , which tie in with the specific syllabus sections.

Electrolysis appears in Chapter 7 and quantitative electrolysis in Chapter The chapter on reaction kinetics Chapter 21 includes material about catalysis whilst the organic chemistry section has been rewritten to accommodate the iodoform reaction and to follow the syllabus more closely.

The last three chapters have been developed to focus on the applications of chemistry Paper 4B. These chapters contain a wealth of material and questions which will help you gain confidence to maximise your potential in the examination. Important definitions are placed in boxes to highlight key concepts. Several features of the book are designed to make learning as effective and interesting as possible. These relate directly to the statements in the syllabus, so you know what you should be able to do when you have completed the chapter.

They often address misunderstandings that commonly appear in examination answers. The detailed answers can be found at the back of the book. These are to stimulate interest or to provide extension material.

They are not needed for the examination. Examples are also given of how to process the results of these experiments.

Learning outcomes Candidates should be able to: define the terms relative atomic, isotopic, molecular and 12 formula masses based on the C scale analyse mass spectra in terms of isotopic abundances no knowledge of the working of the mass spectrometer is required calculate the relative atomic mass of an element given the relative abundances of its isotopes or its mass spectrum define the term mole in terms of the Avogadro constant define the terms empirical and molecular formulae calculate empirical and molecular formulae using combustion data or composition by mass.

Over the past two centuries, chemists have learnt more and more about how. They have also found out the right conditions to allow these materials to react together to make new substances, such as dyes, plastics and medicines.

When we make a new substance it is important to mix the reactants in the correct proportions to ensure that none is wasted. In order to do this we need to know about the relative masses of atoms and molecules and how these are used in chemical calculations.

When we perform chemical calculations, we need to know how heavy one atom is compared with another. The mass of a single atom is so small that it is impossible to weigh it directly. To overcome this problem, we have to weigh a lot of atoms. Scientists have chosen to use the isotope carbon as the standard.

This has been given a mass of exactly 12 units. The mass of other atoms is found by comparing their mass with the mass of carbon atoms. This is called the relative atomic mass, Ar. Figure 1. The relative atomic mass is the weighted average mass of naturally occurring atoms of an element on a scale where an atom of carbon has a mass of exactly 12 units.

For compounds containing ions we use the term relative formula mass. This is calculated in the same way as for relative molecular mass. It is also given the same symbol, Mr. For example, for magnesium hydroxide:. We use the average mass of the atom of a particular element because most elements are mixtures of isotopes.

For example, the exact Ar of hydrogen is 1. This is very close to 1 and most Periodic Tables give the Ar of hydrogen as 1. However, some elements in the Periodic Table have values that are not whole numbers. For example, the Ar for chlorine is This is because chlorine has two isotopes.

In a sample of chlorine, chlorine makes up about three-quarters of the chlorine atoms and chlorine makes up about a quarter. Relative isotopic mass Isotopes are atoms which have the same number of protons but different numbers of neutrons see page We use the term relative isotopic mass for the mass of a particular isotope of an element on a scale where an atom of carbon has a mass of exactly 12 units. For example, the relative isotopic mass of carbon is If we know both the natural abundance of every isotope of an element and their isotopic masses, we can calculate the relative atomic mass of the element very accurately.

To find the necessary data we use an instrument called a mass spectrometer. Relative molecular mass, Mr The relative molecular mass of a compound Mr is the relative mass of one molecule of the compound on a scale where the carbon isotope has a mass of exactly 12 units.

We find the relative molecular mass by adding up the relative atomic masses of all the atoms present in the molecule. For example, for methane: formula atoms present add Ar values Mr of methane 2. It also compares how much of each isotope is present — the relative abundance. A simplified diagram of a mass spectrometer is shown in Figure 1. You will not be expected to know the details of how a mass spectrometer works, but it is useful to understand how the results are obtained.

The atoms of the element in the vaporised sample are converted into ions. The stream of ions is brought to a detector after being deflected bent by a strong magnetic field. As the magnetic field is increased, the ions of heavier and heavier isotopes are brought to the detector. Fact file Laser-microprobe mass spectrometry can be used to confirm that a pesticide has stuck to the surface of a crop plant after it has been sprayed.

Determination of Ar from mass spectra The detector is connected to a computer which displays the mass spectrum. Table 1. In the case of lead, Table 1. We can use the data obtained from a mass spectrometer to calculate the relative atomic mass of an element very accurately.

We can use this method to calculate the relative atomic mass of neon from its mass spectrum, shown in Figure 1. The mass spectrum of neon has three peaks: 20 Ne Note that this answer is given to 3 significant figures, which is consistent with the data given. The formula of a compound shows us the number of atoms of each element present in one formula unit or one molecule of the compound.

So the ratio of mass of hydrogen atoms to oxygen atoms in a water molecule is 2 : No matter how many molecules of water we have, this ratio will always be the same. But the mass of even atoms is far too small to be weighed. We have to scale up much more than this to get an amount of substance which is easy to weigh. The relative atomic mass or relative molecular mass of a substance in grams is called a mole of the substance. The abbreviation for a mole is mol.

We define the mole in terms of the standard carbon isotope see page 1. One mole of a substance is the amount of that substance which has the same number of specific particles atoms, molecules or ions as there are atoms in exactly 12 g of the carbon isotope.

A high-resolution mass spectrometer can give very accurate 16 relative isotopic masses. Because of this, chemists can distinguish between molecules such as SO2 and S2 which appear to have the same relative molecular mass. We often refer to the mass of a mole of substance as its molar mass abbreviation M.

The number of atoms in a mole of atoms is very large, 6.

He guessed that she had got into the habit of tireless sightseeing, given what he believed of this woman. It had not been in the water for five years and was falling to pieces. Although Maggie recognized it was no longer for her benefit, his sleep an amalgam of tossing and dream shreds.

 Мне нужен ключ, - повторила Сьюзан. - У меня его. Отпусти меня! - Он попробовал приподняться, но не смог даже повернуться. В перерывах между сигналами Сьюзан выкрикнула: - Ты - Северная Дакота, Энсей Танкадо передал тебе копию ключа. Он нужен мне немедленно.

Сьюзан посмотрела на него и подумала о том, как жаль, что этот человек, талантливый и очень ценный для АНБ, не понимает важности дела, которым занимается агентство. - Грег, - сказала она, и голос ее зазвучал мягче, хотя далось ей это нелегко.  - Сегодня я не в духе. Меня огорчают твои разговоры о нашем агентстве как каком-то соглядатае, оснащенном современной техникой. Эта организация создавалась с единственной целью - обеспечивать безопасность страны.

На террасе тоже было полно панков, но Беккеру она показалась чем-то вроде Шангри-Ла: ночное летнее небо над головой, тихие волны долетающей из зала музыки. Не обращая внимания на устремленные на него любопытные взгляды десятков пар глаз, Беккер шагнул в толпу. Он ослабил узел галстука и рухнул на стул у ближайшего свободного столика. Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность. Сдвинув в сторону пустые пивные бутылки, Беккер устало опустил голову на руки.

Сейчас она держалась подчеркнуто сдержанно, и это пугало его еще сильнее. - Так в чем же проблема, Фил? - спросил Стратмор, открывая холодильник.  - Может, чего-нибудь выпьешь. - Нет, а-а… нет, спасибо, сэр.  - Ему трудно было говорить - наверное потому, что он не был уверен, что его появлению рады.  - Сэр, мне кажется… что с ТРАНСТЕКСТОМ какая-то проблема. Стратмор закрыл дверцу холодильника и без тени волнения взглянул на Чатрукьяна.

Затем раздался крик: - Нужно немедленно вызвать Джаббу. Послышались другие звуки, похожие на шум борьбы. ГЛАВА 55 - Ты уселся на мое место, осел. Беккер с трудом приподнял голову. Неужели в этой Богом проклятой стране кто-то говорит по-английски.

Любовь. Дэвид Беккер должен был погибнуть за первое, второе и третье. ГЛАВА 103 Стратмор возник из аварийного люка подобно Лазарю, воскресшему из мертвых.

Еще в автобусе Беккер смирился с мыслью, что его миссия провалилась. Пора звонить Стратмору и выкладывать плохую новость: поиски зашли в тупик. Он сделал все, что мог, теперь пора ехать домой. Но сейчас, глядя на толпу завсегдатаев, пытающихся попасть в клуб, Беккер не был уверен, что сможет отказаться от дальнейших поисков.

Довольно консервативные брюки в клетку, белая блузка без рукавов. В руке красная туристская сумка фирмы Л. Белл.

Именно он и подал ручную команду на отзыв Следопыта. Вопрос насколько. уступил место другому - с какой целью?. У Хейла не было мотивов для вторжения в ее компьютер.

Стратмор покачал головой, отказываясь верить тому, что услышал. - Не может быть, чтобы Грег Хейл был гарантом затеи Танкадо. Это полный абсурд.

В этом и заключается наша работа. Это наш долг.
