Answer:
the number of protons and neutrons in an atom
Explanation:
To find the atomic number you just have to add the protons to neutrons.
Phase transfer catalyst is used when oxidizing methoxybenzyl alcohol because it is able to dissolve in both the ethyl acetate and the aqueous layers.
What is phase transfer catalyst?
A phase-transfer catalyst, often known as a PTC, is a catalyst that helps a reactant move from one phase into another where a reaction takes place. Heterogeneous catalysis features a unique subset known as phase-transfer catalysis.
In the absence of a phase-transfer catalyst, ionic reactants are frequently soluble in an aqueous phase but insoluble in an organic phase. When introducing salts into the organic phase, the catalyst acts as a detergent. When a phase-transfer catalyst is added, the reaction is said to be catalyzed, which means it is accelerated.

(2) the motion of the gas particles is random and straight-line, they cannot be influenced by outside forces, one example being a magnetic field.
Answer:
MgCl₂ and H₂
Explanation:
The reaction between Magnesium and Hydrochloric acid is a single replacement reaction. In a single replacement, a metallic ion replaces another ion based on their positions in the activity series.
The reaction can be written as:
Mg + HCl → ?
The ionic form can be written as:
Mg + H⁺ + Cl⁻ → ?
Now lets look at the reaction halves:
Mg → Mg²⁺ + 2e⁻ This is an oxidation half in which 2e⁻ is lost
2H⁺ + 2e⁻ → H₂ This is a reduction half in which 2e⁻ is gained
In the activity series, Mg is higher up and is able to replace the hydrogen ions that in the lower part of the series.
Combining both reaction halves, we have:
Mg + 2H⁺ → Mg²⁺ + H₂
If we include the spectator ions we have:
Mg + 2HCl → MgCl₂ + H₂
