pairs-
water breaks down into
hydrogen and oxygen.

leaves make starch using
chlorophyll and carbon dioxide.

food burns in oxygen gas
and releases a lot of energy.

adding vinegar (acid) to
baking soda (alkali) gives
a product that is neither
acidic nor alkaline.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force
