Answer:
covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms
the sharing of electrons allows each atom to attain the equivalent of a full outer shell, corresponding to a stable electronic configuration.
Explanation:
You’ve not put anything below so I’m not sure what the options are but the relative charge of a proton is +1
It is called a proton I hope this helps
is the product of a reaction between a strong acid and a sulfite ion (which acts as a base).
A chemical reaction in which an acid and a base interact quantitatively is known as neutralisation or neutralisation. By neutralising a reaction in water, surplus hydrogen or hydroxide ions are removed from the solution.
Despite being a weak base, the sulfite ion can hydrolyze to form basic solutions. The equilibria in an acidic solution are changed to create sulphurous acid, which leads to the development of SO2 gas. A colourless gas with a distinctive suffocating smell, sulphur dioxide.
The reaction mechanism is as follows;
⇒

⇒ 
Therefore,

Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
