The moles of methane that are produced when 25.1 moles of CO2 gas react with excess H2 is 25.1 moles

calculation

write the equation for the reaction

that is CO2 +4 H2 → CH4 +2H2O

from the equation above the mole ratio between CO2 to CH4 is 1:1 therefore the moles of CH4 is also= 25.1 moles

The chemical equation for this reaction is this:
CO2 + 4H2 = CH4 + 2H2O
 from the equation, the mole ration of CO2 to CH4 is ratio 1:1
and CH4 = 25.1
The mole ratio of H2 to H2O is 4:2
therefore, mole of H2 = 19.1* 4/2 = 38.2
The moles of methane produced is 38.2 moles

Which of these statement(s) is/are true about a balloon filled with 1.00 mol N2 (g) at STP?
lara [203]

Answer:

I. The balloon has a volume of 22.4L

III. The balloon contains 6.022x10^23 molecules.

Explanation:

At stp, it has been proven that 1mole of a gas occupy 22.4L.

Therefore, option (i) is correct.

The molar mass N2 = 14.01 x 2 = 28.02g/mol

Number of mole of N2 = 1 mole

Mass of N2 =..?

Mass = mole x molar Mass

Mass of N2 = 1 x 28.02 = 28.02g.

The mass content of the balloon is 28.02g, therefore, option (ii) is wrong.

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of N2 also contains 6.02x10^23 molecules

Therefore, option (iii) is correct.

The correct options to the question are:

Option i and option iii
