Besides water, what is the product of a Neutalization Reaction betwe H2CrO4 and Ca(OH)2? en H2CrO4 and Ca(OH)2?

a. CaCro
b. Cacro4
c. Ca2CrO 42
d. Ca2(CrO4)2

The answer to your question is b. CaCrO₄

Explanation:

Data

H₂CrO₄ reacts with Ca(OH)₂

Process

H₂CrO₄ is an acid and Ca(OH)₂ is a base then this is a neutralization reaction.

H₂CrO₄ is an acid and Ca(OH)₂ is a base.

In a neutralization reaction, the products will always be water and a binary or ternary salt.

In the reaction, the salt will be Calcium chromate

Balanced chemical reaction

                          H₂CrO₄  +   Ca(OH)₂   ⇒   CaCrO₄  + 2H₂O

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
