Be sure to answer all parts. One of the compounds used to increase the octane rating of gasoline is toluene (pictured). Suppose 0.366 mL of toluene (d = 0.867 g/mL) is consumed when a sample of gasoline burns in air.

(a) How many grams of oxygen are needed for complete combustion of the toluene?

(b) How many total moles of gaseous products form?

(c) How many molecules of water vapor form?

The molecules contain like 54 of water 

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
