N(Ca)/2 = n(O)/1 = n(CaO)/2
The calcium and the Calcium Oxide are divided by 2 because of their coefficients
there is no number in front of the oxygen so it is over one.
Hope this helped!!
Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid. The baking soda and vinegar reaction is actually two separate reactions. ... The carbonic acid formed as a result of the first reaction immediately begins to decompose into water and carbon dioxide gas.
Answer:
Kc = 70
Explanation:
This is the reaction:
N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
Let's make the expression for K, with concentration at equilibrium and in molarity.
Kc = [NH₃]² / [H₂]³ . [N₂]
Kc = (2.1)² / (0.5)³ . 0.5
Kc = 4.41 / 0.0625 → 70
Answer:
It is an ionic compound that consists of one calcium cation Ca2+ and two chlorine anions. The bivalent calcium metal forms an ionic bond with two chlorine atoms. The formation of cacl2 happens mainly by reacting limestone (CaCo3) with hydrochloric acid (HCl).
