What are the spectator ions in this equation?

dangina [55]

The given question is incomplete. The complete question is :

What is the net ionic equation for the following reaction?

$H_2CrO_4+Ba(OH)_2$

Answer : The spectator ions are $Ba^{2+}$ and $CrO_4^{2-}$

Explanation:

Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

$2H^+(aq)+CrO_4^{2-}(aq)+Ba^{2+}(aq)+2OH^-(aq)\rightarrow Ba^{2+}(aq)++CrO_4^{2-}(aq)+H_2O(l)$

The ions which are present on both the sides of the equation are barium and chromate ions. and hence are not involved in net ionic equation.

Hence, the net ionic equation is $H^++OH^-\rightarrow H_2O$

Anon25 [30]

Answer:

Number of moles = 2 mol

Explanation:

Given data:

Mass of carbon = 24 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of carbon is 12 g/mol.

Now we will put the values in formula.

Number of moles = 24 g/ 12 g/mol

Number of moles = 2 mol
