Answer:
The net ionic equation will be MgCl₂ + 2 NaOH → Mg(OH)₂ + 2 NaCl
Explanation:
Ionization of MgCl₂ is as follows
MgCl₂ → Mg²⁺ + 2 Cl⁻
Ionization of NaOH is as follows
NaOH → Na⁺ + OH⁻
It is a one type of substitution reaction where OH⁻ combined with Mg²⁺ to give magnesium hydroxide .
On the other hand Cl⁻ combined with Na⁺ to give sodium chloride as product.
Using proper stoichiometry to balanced the number of atoms in both side .
Answer:16.38085
Explanation:Aline the decimals then start multiplying.
Answer:
1.2 moles
Explanation:
this is the balanced equation for the reaction of oxygen (O2) and hydrogen (H2), usually we don't write the 1 in front of O2
2H₂ + 10₂ → 2H₂O
the molar ratio of hydrogen to oxygen is 2 : 1
we are trying to react with 2.4 mol of H2 so the moles of O2 is half the number of moles of H2 = 2.4 ÷ 2 = 1.2 mol
another way to think of it:
2H₂ + 10₂
2 : 1
2.4 mol : x mol
to get from 2 to 2.4 multiply by 1.2, so do the same to the other side
1 × 1.2 = 1.2 mol
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases.
Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases.
For the given chemical reaction:
The half reactions for the above reaction are:
Oxidation half reaction: 
Reduction half reaction: 
From the above reactions, copper is loosing its electrons. Thus, it is getting oxidized.
Silver ion is gaining electrons and thus is getting reduced.
Hence, the correct answer is Option A.
