Yield and Atom Economy

This page discusses the concepts of yield and atom economy, which are important for understanding the efficiency of chemical reactions in OCR A level Chemistry flashcards pdf.

The page explains:

• 100% yield is difficult to achieve due to incomplete reactions, side reactions, and loss during purification. • Actual yield is always lower than theoretical yield. • Percentage yield is calculated using the formula: (actual yield ÷ theoretical yield) × 100 • Atom economy is a measure of how well atoms have been utilized in a reaction.

Definition: Atom economy - A measure of the efficiency of a chemical reaction in terms of all atoms involved.

Example: A reaction with high atom economy would incorporate most of the atoms from the reactants into the desired product, with minimal waste.

Formulas for Common Ions and Compounds

This page focuses on the formulas for common ions and compounds that are crucial for OCR A level chemistry paper 1. Understanding these formulas is essential for balancing equations and performing chemical calculations.

The page lists the formulas for several important ions and compounds:

• Ammonium (NH4+) • Carbonate (CO3²-) • Hydroxide (OH-) • Sulfate (SO4²-) • Nitrate (NO3-) • Ethanoic acid (CH3COOH) • Sulfuric acid (H2SO4)

Highlight: Memorizing these formulas is crucial for success in A-level chemistry exams and practical work.

Vocabulary: Ion - An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

Atomic Structure and Periodic Table

This page delves into the fundamental concepts of atomic structure and the organization of the periodic table, which are essential topics in OCR A level Chemistry flashcards pdf.

Key points covered include:

• The mass of an electron is 1/1836 of the mass of a proton. • Atomic mass refers to the total number of protons and neutrons in an atom. • Atomic number indicates the number of protons in an atom. • Isotopic mass is compared to 1/12 of the mass of carbon-12. • Relative atomic mass is the weighted mass compared to 1/12 of carbon-12. • The periodic table lists elements in order of atomic number.

Definition: Isotopic mass - The mass of an isotope of an element compared to 1/12 of the mass of a carbon-12 atom.

Example: The atomic number of hydrogen is 1, which means it has 1 proton in its nucleus.

Relative Atomic Mass and Atomic Number

This page focuses on the concepts of relative atomic mass and atomic number, which are fundamental to understanding atomic structure in A level chemistry formulas and atomic mass pdf.

The page explains that:

• Relative atomic mass is the larger number found above or below an atom on the periodic table, representing the number of protons and neutrons. • Atomic number tells us the number of protons an element has. • The charge of zinc is 2+ (Zn²+). • Relative atomic mass is defined as the weighted mean mass of an atom of an element relative to 1/12 of the mass of an atom of carbon-12.

Definition: Relative atomic mass - The weighted average mass of an atom of an element, compared to 1/12 of the mass of a carbon-12 atom.

Example: The relative atomic mass of oxygen is approximately 16, while its atomic number is 8.

Stoichiometry and Yield Calculations

This page covers important concepts related to stoichiometry and yield calculations, which are crucial for OCR A level chemistry flashcards Anki.

Key points include:

• Percent by mass is calculated using the formula: (mass of element ÷ Mr of compound) × 100 • Stoichiometry refers to the ratio of amounts in a balanced equation • The limiting reactant is the reactant that is fully used up in a reaction • Theoretical yield is the maximum possible amount of product in a reaction

Definition: Stoichiometry - The quantitative relationship between reactants and products in chemical reactions.

Example: In the reaction 2H2 + O2 → 2H2O, the stoichiometric ratio of hydrogen to oxygen is 2:1.

Relative Atomic Mass and Isotopes

This page discusses the calculation of relative atomic mass and the concept of isotopes, which are important topics in Relative atomic mass formula and Isotopes notes pdf.

The page explains:

• Relative atomic mass is calculated using the formula: (mass × abundance) of each isotope ÷ 100. • Isotopes are atoms of the same element with different mass numbers due to a different number of neutrons. • Isotopic mass is compared with 1/12 of the mass of carbon-12. • The percentage abundance of an isotope is found using a mass spectrometer.

Definition: Isotope - Atoms of the same element with the same number of protons but a different number of neutrons.

Example: Carbon-12, carbon-13, and carbon-14 are isotopes of carbon with 6, 7, and 8 neutrons respectively.
