Answer: CaCO3 reaction.
Explanation: CaO and combine together to result in the formation of calcium carbonate compound. we know it is a synthesis reaction.so we can conclude that the most likely products of Cao + co2 → CaCO3 reaction.
Answer:
Another way to describe a reaction that gives out free energy is Spontaneous Reaction
1mol N2 + 3mol H2 → 2mol NH3
<span>Because you are dealing with gases, at the same temperature and pressure you can say: </span>
<span>1volume N2 + 3 volumes H2 → 2 volumes NH3 </span>
<span>OR: 4 volumes reactants = 2 volumes products. </span>
<span>You have 1.9+5.7 = 7.6 volumes reactants, which must give 7.6/2 = 3.8 volumes of NH3 </span>
<span>Answer: 3.8 litres of NH3 will be formed</span>
Sulfurous acid is the chemical compound with the formula H₂SO₃.
Balanced chemical reaction of sulfurous acid in water:
H₂SO₃(aq) + H₂O(l) ⇄ HSO₃⁻(aq) + H₃O⁺(aq).
or H₂SO₃(aq) ⇄ HSO₃⁻(aq) + H⁺(aq).
Ka is the acid
dissociation constant, which quantifies the extent of acid dissociation (in
this example H₂SO₃) in water.<span>
Ka = [</span>HSO₃⁻]·[H₃O⁺] / [H₂SO₃].<span>
or Ka = [</span>HSO₃⁻<span>]·[H⁺] / [</span>H₂SO₃].
