It takes 1 minute for a certain amount of potassium phosphate (KH2PO4) to dissolve in 100 grams of water at 50 °C. Which of the following will most likely happen if the same sample of potassium phosphate is dissolved in 100 grams of water at 20 °C?

0.4

Explanation:

from

1%=50

x%=20

where by

1%=1÷100

x%=x÷100

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
