Answer:
Net ionic: 
Explanation:
in
reacts with
to form
and
.
Due to this acid-base reaction,
become soluble whenever
is added to suspension of
.
In this reaction,
acts as an acid and
acts as a base.
Molecular equation: 
Total ionic: 
Net ionic: 
The balanced chemical reaction is written as:
<span>CH4 (g) + 2 O2 (g) ----> CO2 (g) + 2 H2O (g)
</span>
We are given the amount of water to be produced from the reaction. This amount will be used for the calculations. Calculations are as follows:
12.4 L H2O ( 1 mol / 22.4 L ) ( 1 mol CH4 / 2 mol H2O ) ( 22.4 L / 1 mol ) = 6.2 L CH4
Answer:
Explanation:
Fe⁺²(aq) + ClO₂(aq) → Fe⁺³(aq) + ClO₂⁻(aq)
Here oxidation number of Fe is increased from +2 to +3 , so Fe is oxidised .
The oxidation number of Cl is reduced from + 4 to +3 so Cl is reduced .
So ClO₂(aq) is oxidising agent and Fe⁺²(aq) is reducing agent .
Answer:
The half life time of first order reaction is 1.3 sec
Explanation:
Given:
First order rate constant

Initial concentration
M
From the formula of first order half life time,

So half life time is given by,

sec
Therefore, the half life time of first order reaction is 1.3 sec.
