How much volume is needed, if given 92.0 L of Hydrogen gas in a container of 612 kPa and reduces to 228kPa

246.94 litres is the volume is needed, if given 92.0 L of Hydrogen gas in a container of 612 kPa and reduces to 228kPa.

Explanation:

Data given:

Initial volume of hydrogen gas in the container P1 = 92 litres

initial pressure of hydrogen gas in the container  V1 = 612 kPa

final pressure of hydrogen gas on the container P2= 228kPa

final volume of hydrogen gas on the container V2 =?

from the data we will require equation of Boyle's law to calculate the unknown volume:

P1V1 = P2V2

V2 =

putting the values in the equation:

V2 =

V2 = 246.94 Litres.

246.94 litres will be the volume of the hydrogen gas when pressure geta reduced to 228 kPa.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
