AQA AS-LEVEL PHYSICS 7407/1 PAPER 1 JUNE 2022 QUESTION PAPER. A sample of bromine gas contains a mixture of two isotopes. An experiment is done to find the percentage of each isotope in this sample. 0 2 . 1 In the experiment, the gas is ionised by a beam of electrons. Explain how the beam of electrons causes a particle of the gas to have a charge of +1e. The gas consists of bromine molecules. Each molecule has two bromine atoms. The experiment finds that the bromine molecules contain 158,...

AC-HPAT Chemistry Study Guide 2023 with complete solution double-displacement reaction A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products Precipitate precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid fro...
