Answer to Question #88178 in General Chemistry for Kaitlynn Schenk

Question

When the following equation is balanced properly under basic conditions, what are the coefficients of the species shown?

____ Mn(OH)2 + ____ P -> ____ MnO2 + _____ PH3

Water appears in the balanced equation as a ______ (reactant, product, neither) with a coefficient of _____ . (Enter 0 for neither.)

How many electrons are transferred in this reaction? ______

Answer 1

Balanced chemical equation:

$$3Mn(OH)_2 +2P \rightarrow 3MnO_2 + 2PH_3$$

Water appears in the balanced equation as a neither with a coefficient of 0.

6 electrons are transferred in this reaction:

$$(Mn^{+2} \rightarrow Mn^{+4} + 2e^-)\times 3$$

$$(P^0 + 3e^-\rightarrow P^{-3})\times 2$$
