Answer: 1.) renewable resources can be replenished as fast as they are used. Nonrenewable resources are unable to be replaced at the same rate at which they are used. 2.) nonrenewable energy sources will eventually run out, leaving people to figure out how to continue running their cars, homes, and busines. They must find alternative sources of energy. Since renewable energy resources that will never run out, it is a great option.
Explanation:
Answer:
V2= 625 cm^3
Explanation:
P1 × V1 = P2 × V2
P1 (initial pressure)=125 kPa
V1 ( initial volume)= 450 cm^3
P2 (final pressure)=90kPa
V2 (final volume)= ?
Rearrange the equation to make V2 the subject, since it is the value we are trying to find
V2=(P1 × V1)/P2
V2= (125 ×450)/90
V2= 625 cm^3
0.5 mols of NaCl* 58 grams of NaCl/1 mol of NaCl = 29 grams of sodium chloride
