Question

Magnesium hydroxide reacts with potassium phosphate to produce potassium hydroxide and magnesium phosphate. In the balanced chemical equation for this change, what are the lowest, whole number coefficients? Match the species to the correct number.

-Magnesium hydroxide
-Potassium phosphate
-Potassium hydroxide
-Magnesium phosphate

Answer 1

The stoichiometric coefficient of
`Mg(OH)_2=3`

The stoichiometric coefficient of
`K_3PO_4=2`

The stoichiometric coefficient of
`KOH=6`

The stoichiometric coefficient of
`Mg_3(PO_4)_2=1`

Step-by-step explanation:

The balanced chemical reaction :

`3Mg(OH)_2+2K_3PO_4\rightarrow 6KOH+Mg_3(PO_4)_2`

According to reaction, 3 moles of magnesium hydroxide reacts with 2 moles of potassium phosphate to give 6 moles potassium hydroxide and 1 mole of magnesium phosphate as products.

The stoichiometric coefficient of
`Mg(OH)_2=3`

The stoichiometric coefficient of
`K_3PO_4=2`

The stoichiometric coefficient of
`KOH=6`

The stoichiometric coefficient of
`Mg_3(PO_4)_2=1`
