What is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? Ass

jeyben [28]

Answer : The net ionic equation will be,

$Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)$

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : It is defined as the ions present on reactant and product side that do not participate in the reactions. That means the same ions present on both the sides.

The given balanced ionic equation will be,

$BaSO_4(aq)+H_2SO_4(aq)\rightarrow BaSO_4(s)+H_2O(aq)$

The ionic equation in separated aqueous solution will be,

$Ba^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)+2H^+(aq)+2OH^-(aq)$

In this equation, $H^+\text{ and }OH^-$ ions are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

$Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)$

Answer:

Half life = 79.67 sec

Explanation:

Given that:

k = $8.7\times 10^{-3}\ s^{-1}$

The expression for half life is shown below as:-

$t_{1/2}=\frac{\ln2}{k}$

Where, k is rate constant

So,

$t_{1/2}=\frac{\ln2}{8.7\times 10^{-3}\ s^{-1}}$

$t_{1/2}=114.94252\ln \left(2\right)\ sec=79.67\ sec$

Half life = 79.67 sec
