The answer to your question is:  B. Nickel Sulfate

Explanation:

A. Nickel sulfur oxide  this compound do not exist, this option is incorrect.    

B. Nickel sulfate  This compund exist and the formula is NiSO₄

C. Nickel oxygen sulfide  This compound do not exist, the order of the names is inocrrect.

D. None of these This option is incorrect because because letter B is correct.

the answer is definitely c.

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 :
