Answer:
0.0125mol
Explanation:
Molarity (M) = number of moles (n) ÷ volume (V)
n = Molarity × Volume
According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:
1000mL = 1L
250mL = 250/1000
= 0.250L
n = 0.05 × 0.250
n = 0.0125
The number of moles of NaOH is 0.0125mol.
Explanation: This is a reaction of oxidation of
in the presence of acidified
. Acidified
is a strong oxidizing agent.
To balance out the
on the reactant side, we write
on the product side.
Balancing out the following reaction gives us:

Precipitation :)

<u>Answer:</u> The final volume will be 14.85 L.
<u>Explanation:</u>
To calculate the final volume when temperature increases, we use Charles' Law.
This law states that volume is directly proportional to the temperature of the gas if number of moles and pressure remains constant.

where,
= Initial volume and temperature
= Final volume and temperature
We are given:

Putting values in above equation, we get:


Hence, the final volume of the gas is 14.85L
