How many grams of H₂ are produced with the reaction of 36 grams of water? *

10 points

0.25 g

0.50 g

1.0 g

2.0 g

Explanation:

Hello,

In this case, water decomposition is represented by:

Thus, since water molar mass is 18 g/mol and hydrogen molar mass is 2 g/mol and they are in a 2:2 molar ratio, the produced grams of hydrogen result:

Best regards.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
