Answer:
Nitric acid reacts with sodium carbonateto form sodium nitrate, carbon dioxide and water. 2HNO3+Na2CO3→2NaNO3+CO2+H2O.
<span>In a sample of solid Ba(NO3)2 the ratio of barium ions to nitrate ions is would be one is to 2 or 1:2. Barium ion has a formal charge of positive two which means that it needs two ions which has a formal charge of negative one or 1 ion with the formal charge of negative two. However, for this case, it is bonded to a nitrate ion which has a formal charge of negative one. Therefore, it needs two nitrate ions so that for every 1 atom of barium ion, we need two ions of nitrate ions.</span>
NH4+1 ammonium
NO3-1 nitrate
Answer:
Equilibrium concentration of reactants and products:
Explanation:
The equilibrium constant of the reaction =
Mole sof HI = 0.372 mol
Volume of the vessel = 1.00 L
Initial concentration of HI =
0.372 M
At equilibrium
(0.372-2x) M x x
An expression of an equilibrium constant will be given as;
Solving for x;
x = 0.03935
Equilibrium concentration of reactants and products:
