Answer:

2KOH + H₂SO₄ → K₂SO₄ + 2H₂O.

Explanation:

  • This is an acid-base reaction which produces salt and water according to the balanced equation:

<em>2KOH + H₂SO₄ → K₂SO₄ + 2H₂O.</em>

<em></em>

it is clear that 2.0 moles of KOH react with 1.0 mole of H₂SO₄ to produce 1.0 mole of K₂SO₄ and 2.0 moles of H₂O

How many grams of oxygen is needed to completely react with 9.30 moles of aluminum
Orlov [11]
Balanced chemical equation:

* moles of oxygen

4 Al + 3 O2 = 2 Al2O3

4 moles Al -------------- 3 moles O2
9.30 moles Al ---------- moles O2

moles O2 = 9.30 * 3 / 4

moles O2 = 27.9 / 4 => 6.975 moles of O2

Therefore:

Molar mass O2 = 31.9988 g/mol

n = m / mm

6.975 = m / 31.9988

m = 6.975 * 31.9988

m = 223.19 of O2

In the reaction
NemiM [27]

Answer:

3 moles of CO are needed

Explanation:

Given data:

Number of moles of CO used = ?

Mass of Fe produced = 112 g

Solution:

Chemical equation:

Fe₂O₃ + 3CO      →        2Fe + 3CO₂

Number of moles of Fe:

Number of moles = mass/ molar mass

Number of moles = 112 g/ 55.85 g/mol

Number of moles = 2.00 mol

Now we will compare the moles of iron and CO.

                   Fe        :         CO

                   2          :         3

Thus, 3 moles of CO are needed.
