What is the total number of moles represented by 20 grams of CACO3
Nutka1998 [239]

Answer:

B. 0.2.

Explanation:

  • We can use the relation:

<em>n = mass/molar mass</em>

mass of CaCO₃ = 20 g, molar mass of CaCO₃ = 100.0869 g/mol.

<em>∴ n = mass/molar mass = </em>(20 g)/(100.0869 g/mol) <em>= 0.1998 ≅ 0.2 mol.</em>

<em></em>

<em>So, the right choice is: B. 0.2.</em>

mylen [45]

Answer:

HC_2H_3O_2_{(aq)}\rightarrow H^+_{(aq)}+C_2H_3O_2^-_{(aq)}

Explanation:

Arrhenius theory:-

The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.

According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, H^+.

So,

The expression for acid, HC_2H_3O_2 is:-

HC_2H_3O_2_{(aq)}\rightarrow H^+_{(aq)}+C_2H_3O_2^-_{(aq)}
