I need to balance the equation __kciO3➡️__kcio4+__ KCIAnd How many moles of potassium chloride are produced from 3.90 moles of potassium chlorate ?

Sagot :

Explanation:

To balance the equation, we need to have the same number of atoms of each element on both sides of the equation.

So in this case:

4KCIO3 → 3KCIO4 + KCI

where:

reactants:

K - 4

Cl - 4

O - 12

Products:

K - 4

Cl - 4

O - 12

Potassium chloride is KCl and potassium chlorate is KClO3. The balanced reaction equation tells us that:

4 mol of KClO3 produces 1 mol of KCl, we know it because of the equation:

4 KCIO3 → 3 KCIO4 + 1 KCI

So we can do a rule of 3 to find out the quantity in moles produced when we have 3.90 moles of KClO3:

4 mol KClO3 --- 1 mol KCl

3.9 moles KClO3 --- x

4x = 1*3.9

x = 3.9/4

x = 0.975 moles

Answer: 4 KCIO3 → 3 KCIO4 + KCI and 0.975 moles.
