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,...

The most common isotope of hydrogen has one proton, no neutrons, and one electron. An isotope of hydrogen with 1 neutron would have: - Answer- an atomic number of 1 and a mass number of 2 In a covalent bond: - Answer- electrons are shared between atoms so that all atoms have full outer shells A property of a system that is present at one level of organization but absent at the levels below is called: - Answer- an emergent property An ionic bond is - Answer- weaker than a covalent bond ...

Station 1. You have run an experiment studying the effects of the molecular weight of a compound on the rate of diffusion in agar. Compound X has a molecular weight of 25.3 g/mol and compound Y has a molecular mass of 156.2 g/mol. On two separate agar plates, 0.1 g of each substance were transferred and allowed to diffuse for 2 hours. The results below were obtained. Use this information about this situation to answer the following three questions. 1. Question: (CO 1) What was the independent v...
