When the following equation is balanced properly under basic conditions, what are the coefficients ofthe species shown? NH3 F N2Hi 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? Submit Answer Retry Entire Group 9 more group attempts remaining

Explanation / Answer

Part A

the balanced equation is

2NH3 + F2 + 2OH-   ------> 2F- + N2H4 + 2H2O

Water appears as a product with a coefficient of 2.

The number of electrons transferred in thei sreaction are 2 electrons.

Part B

the balanced equation is

3S-2 + 2P + 6H2O -------> 2PH3 + 3S + 6OH-

Water appears as a reactant with a coefficient of 6

The number of electrons tranferred are 6.
