In order for you to calculate
for the mass of ammonium carbonate, you need to know the molar mass of it and
the nitrogen atoms in the compound. Ammonium carbonate has a molar mass of
96.08 grams per mole. There are two nitrogen atoms in ammonium carbonate which
is equal to 28.02 grams per mole. Divide the molar mass of nitrogen to the
ammonium carbonate, 28.02/96.08 x 100, we get 29.16wt% nitrogen.
The answer is
a. FeCl3 + 3 NaOH = Fe(OH)3 + 3 NaCl
b. 2 C2H2 + 5 O2 = 4 CO2 + 2 H2O
c. Fe2O3 + 3 H2 = 2 Fe + 3 H2O
To balance equations you basically have to make sure each element has an equal amount or number on each side of the equation. If you need more help understanding this, feel free to ask.

Explanation:
Metals are good reducing agents because they are electron donor which causes co-reactant to be reduced in a reaction.
The position of an element in the activity series determines the strength as a reducing agent or not.
Elements higher in the series are good reducing agents, those lower in the series are poor reducing agents.

The value of X for this chemical reaction is 1.65 x 10⁻⁴
<u>Explanation:</u>
Mg (OH)₂(s) <==> Mg²⁺+(aq) + 2OH₋₁(aq)
Kc= 1.80x10⁻¹¹
KC = [Mg²⁺][OH-]²
Let us assume
Put X = [Mg²⁺] and 2x =
[OH-]
1.80x10-11 = (X) (2X)²
1.80x10-11 = 4X³
X³ = 4.5x10⁻¹²
On simplifying the equation we get,
X = 1.65 x 10⁻⁴
The value of X for this chemical reaction is 1.65 x 10⁻⁴
