Min is asked to balance the equation below. Original: Ca3P2 + H2O → Ca (OH) 2 + PH3 Min's result: Ca3P2 + H2O → Ca3 (OH) 2 + PH3 Which best describes Min's method for balancing the chemical equation?

A. It is correct, because now there are three Ca atoms on each side of the equation.

B. It is incorrect, because the identity of the original product has changed.

C. It is correct, because Ca3 (OH) 2 creates a more stable compound.

D. It is incorrect, because the subscript "2" should be added instead.

B. It is incorrect, because the identity of the original product has changed.

Gummi Bear · Answer 2

The correct answer would be B. Min's method is incorrect because she changed the identity of the original product. In balancing reactions, you just write a coefficient before the substances to balance out the elements on both sides. The balanced reaction should be Ca3P2 + 6H2O → 3Ca (OH) 2 + 2PH3.
