Question

In the reaction Ba(OH)₂ + 2 HCl -> BaCl₂ + 2 H₂O, how many moles of HCl are required to react with 1 mol of Ba(OH)₂?

In the reaction Ba(OH)2 + 2 HCl -> BaCl2 + 2 H2O, how many moles of H+ are required to react with 0.225 mol of OH-?

Based on what you know about the stoichiometry of ionic compounds, predict the chemical formula of calcium hydroxide.

a. Ca(OOH)

b. Ca(H20)

c. CaOH

d. Ca(OH)2

Answer 1

→ Solution P.NO!! :- The Cuiven reaction is 1 Balonly + 240) - Ballz + 2420 It is clear that the above res equation in a balanced equation. Here the prefix number of Baloul is I and that of HCL is 2. So, one mole of Balou), reacts with 2 moles of nel OR 2 moles of Hel are required to react with one mole of - Balonla P. No:2 :- from one molecule of Baſoul, we get 2 onions lily Bacon), — Balt + (201) And from one molecule of ucl, we get one ut in iery Hel - (+) + Cir But one mole of the combines of with one mole of our to give H₂o se - 10H + 14t - H₂o. This means, if we have 0.225 moles of onions, then the amount of HP ions required to react with it is 0.225 moles

Q.No.3 Calcium Hydroxide is a molecule which con calcium ions (Cat) and hydroxide ions (on). . Now, charge on calcium ions is +2, and that on hydroxide ion is al. This means to neutralize +2 change of a ions we need 2 On" ions. This can be shown as ca2t + zon - Cacond Formula for Calcium hydroxide is calor), - -
