(H2PO4)- is a base. Which is its conjugate acid?
H2PO4-

The conjugate acid of H2PO4- is H3PO4 or phosphoric acid with a added proton. If it is conjugate acid, add a proton then remove a negative charge. If it is conjugate base, remove a proton then add a negative charge.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
