Answer:

The answer to your question is 3 moles of Fe and 4.5 moles of S

Explanation:

Data

moles of Fe = ?

moles of S = ?

moles of Fe₂S₃

Unbalanced chemical reaction

                    Fe   +  S   ⇒    Fe₂S₃

             Reactants    Elements    Products

                     1                  Fe                2

                     1                   S                 3

Balanced chemical reaction

                    2Fe   +  3S   ⇒    Fe₂S₃

             Reactants    Elements    Products

                     2                  Fe                2

                     3                   S                 3

-Calculate the moles of each reactant

                  2 moles of Fe ------------------- 1 mol of Fe₂S₃

                 x                       -------------------- 1.5 moles Fe₂S₃

                               x = (1.5 x 2) / 1

                                x = 3 moles of Fe

-Calculate the moles of S

                  3 moles of S --------------------- 1 mol of Fe₂S₃

                  x                    --------------------- 1.5 moles of Fe₂S₃

                                x = (1.5 x 3) / 1

                                x = 4.5 moles of S

When a pure sample of KNO3(s) spontaneously dissolves in water at room temperature, the solution becomes quite cold to the touch
jekas [21]

The enthalpy of the solution is <u>positive </u>and the entropy is <u>positive</u>.

Potassium trioxonitrate (V) KNO₃(s) is a strong oxidizing solid substance that when dissolved in water changes to aqueous solution.

In its aqueous solution state, the randomness of molecules increases as a result of that the entropy will also increase leading to the positive state of the entropy.

Similarly, provided that the solution becomes quite cold to the touch, the enthalpy is also in it positive state.

Therefore, we can conclude that the enthalpy of the solution is <u>positive </u>and the entropy is <u>positive</u>.

given the following chemical equation, determine how many grams of N2 are produced by 9.24 of H2O2 nd 6.56g of N2H4
taurus [48]
I think the chemical reaction is:<span>

N2H4 + 2 H2O2-> N2 + 4H2O

We are given the amount reactants allowed to react. This will be the starting point of the reaction. First, is to find the limiting reactant.

9.24 g H2O2 ( 1 mol / 34.02 g ) = 0.27 mol H2O2
6.56  g N2H4 ( 1mol / 32.06) = 0.20 mol N2H4

Since from the reaction we have 1:2 ratio of the reactants then the limiting reactant is hydrogen peroxide. We will use this to find the amount of N2 produced.

0.27 mol H2O2 ( 1 mol N2 / 2 mol H2O2 ) ( 14.01 g N2 / 1 mol N2) =1.89 g N2 </span>
