Answer:
2 electrons
8 electrons
8 electrons
1 electron (just count in the rings for these ones)
19 protons (it says "P=19" in the middle. The P stands for Protons)
K (it's from Latin medieval Latin "kalium")
39 (add proton and neutron amounts to get the approximate atomic mass--electrons are negligible)

Answer:
The question has some part missing which I have added in the attachment.
Explanation:
The reactions given occur under certain reagents, which we are told to pick for each of the reaction synthesis. Conventionally, halogens have the ability to undergo addition reactions with hydrocarbons by breaking down the double or triple bond in them to a single bond, this usually occur by electron donation and electron acceptor.
The attachment shows the reactions and the necessary reagents required for each
Answer:
Equilibrium position shifts right.
Explanation:
According to Le Châtelier's principle, when a chemical system at equilibrium is distributed by a change in conditions, the equilibrium position will shift in a direction that tends to counteract the change.
So, when the concentration of reactant increases, the equilibrium will counteract the change by increasing the concentration of the products, hence shifting right to increase the concentration of water.
Mercury is a homogenous mixture of two or more pure substances
