$NO_2 + H_2 \to NH_3 + H_2 O$

 $2NO_2 + 7H_2 \to 2NH_3 + 4H_2 O$

NO2 + H2 ----> NH3 + H2O

N(+IV) + 7e -----> N(-III) |2
H2(0) - 2e ----> 2H(+I) |7

after: 2NO2 + 7H2 ----> 2NH3 + 4H2O

Epsom salt, a common hydrate, has the formula shown below. If I measure out 125 g of epsom salt to add to my foot soak, what mas

tatiyna

Answer:

The answer to your question is 64.02 g of H₂O

Explanation:

Data

Mass of magnesium sulfate hepta hydrated = 125 g

Mass of water = ?

Process

1.- Calculate the molar mass of the salt and the molar mass of water

molar mass of MgSO₄ 7H₂O = 24 + 32 + 64 + 14 + 112 = 246 g

mass of H₂O = 2 + 16 = 18 g

2.- Use proportions to calculate the mass of water in the epsom salt

246 g MgSO₄ 7H₂O------------------------- 126 g of H₂O

125 g ------------------------- x

x = (125 x 126)/246

x = 15750/246

x = 64.02 g of H₂O
