Areaction produces 92.50 g feso4. how many grams of cuso4 are necessary for this to occur? fe+cuso4⟶cu+feso4

Answer : The mass of needed will be, 97.2 grams.

Explanation : Given,

Mass of = 92.50 g

Molar mass of = 151.908 g/mole

Molar mass of = 159.609 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of obtained from 1 mole of

So, 0.609 moles of obtained 0.609 moles of

Now we have to calculate the mass of .

Therefore, the mass of needed will be, 97.2 grams.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
