2. Iron reacts with superheated steam to form hydrogen gas and the oxide Fe3O4. Calculate the number of moles of hydrogen produc
vekshin1

Answer:

A 0.239mol

Explanation:

From the equation:

We were given that 10g of iron was involved in this chemical reaction

We can establish that :

3moles of Fe would produced 4 moles of Hydrogen gas

Therefore:

Number of moles of iron = mass of Fe / mloar mass of iron

Mass of Fe = 10g

Molar Mass of Fe = 55.85g/mol

Therefore, number of moles of iron= 10/55.85

Number of moles of iron = 0.179mol

3moles of Fe would produced 4 moles of Hydrogen gas

So, 0.179mol of Fe would give 0.179x4/3

The number of mole of Hydrogen gas produced is 0.239mol.

If 25.8 grams of BaO dissolve in enough water to make a 212-gram solution, what is the percent by mass of the solution?
Igoryamba
The correct answer is 12.2% BaO.

The solution is found by dividing the mass of the BaO, which is 25.8 grams, by the total mass of the solution, which is 212 grams, then multiplying it by 100 to get the percentage:
\frac{25.8}{212}*(100) =12.2%
