Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g)
Oxidation means lose of electrons and increase of positive charge so the part which oxidized in this equation is Zn(s) because it converted to Zn²⁺ (i.e. lost two electrons)
A) The class and C) Family would be the only accurate option. Here are the levels from largest to smallest: <span>kingdom, phylum, class, order, family, genus and species.</span>
<span>Photolysis and hydrolysis. These are two methods that can be used to break down a compound into simpler substances and smaller units.
Water which is used to break the bonds of molecules and split molecules is used from hydrolysis. Hydrolysis is made of three types which include;
1. salt hydrolysis.
2. acid hydrolysis.
3. Base hydrolysis.
Photolysis is well known to use energy from light to split the molecule and the same energy is referred to as photons which are used to break builds of molecules.</span>

Answer:
The answer to your question is Pressure 1 = 1.73 atm
Explanation:
Data
Volume 1 = 5 l
Pressure 1 = ?
Volume 2 = 12 l
Pressure 2 = 0.72 atm
Process
To solve this problem use Boyle's law to solve this problem
Pressure 1 x Volume 1 = Pressure 2 x Volume 2
-Solve for Pressure 1
Pressure 1 = Pressure 2 x Volume 2 / Volume 1
-Substitutiion
Pressure 1 = 0.72 x 12 / 5
-Simplification
Pressure 1 = 8.64/5
-Result
Pressure 1 = 1.73 atm
