When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. caco3(s)+2hcl(aq)⟶cacl2(aq)+h2o(l)+ co2(g) how many grams of calcium chloride will be produced when 31.0 g of calcium carbonate is combined with 13.0 g of hydrochloric acid?

19.7822 g

Explanation:

The formula for the calculation of moles is shown below:

Given: For calcium carbonate

Given mass = 31.0 g

Molar mass of calcium carbonate = 100.0869 g/mol

Moles of calcium carbonate = 31.0 g / 100.0869 g/mol = 0.3097 moles

Given: For hydrochloric acid

Given mass = 13.0 g

Molar mass of hydrochloric acid = 36.46094 g/mol

Moles of hydrochloric acid = 13.0 g / 36.46094 g/mol = 0.3565 moles

According to the given reaction:

1 mole of calcium carbonate react with 2 moles of hydrochloric acid

0.3097 moles  of calcium carbonate react with 2 × 0.3097 moles of hydrochloric acid

Moles of HCl = 0.6194 moles

Available moles of HCl = 0.3565 moles

Limiting reagent is the one which is present in small amount. Thus, HCl is limiting reagent. (0.3565 < 0.6194)

The formation of the product is governed by the limiting reagent. So,

2 moles of HCl produces 1 mole of calcium chloride

1 mole of HCl produces mole of calcium chloride

0.3565 moles  of HCl produces mole of calcium chloride

Moles of calcium chloride = 0.17825 moles

Molar mass of calcium chloride = 110.98 g/mol

Mass of calcium chloride = Moles × Molar mass = 0.17825 × 110.98 g = 19.7822 g

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
