If u pass a curve of 3a in a time of 90mins. how much mg will be deposited.

Explanation:

1. Write the equation for the half-reaction.

Mg²⁺ + 2e⁻ ⟶ Mg

The number of electrons transferred (z) is 2 mol per mole of Mg.

2. Calculate the number of coulombs

Q  = It  

3. Mass of Mg

We can summarize Faraday's laws as

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 :
