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.

The pH = -log of hydrogen ion concentration
The more acid a solution is the higher is its concentration of H+ ions and the lower is its pH. Acids have a pH lower that 7.
        
             
        
        
        
Answer:

Explanation:
We are asked to find how much heat a sample of copper absorbs when the temperature is increased. 
Since we know the mass, temperature increase, and specific heat capacity, we can use the following formula to calculate heat. 

The mass of the copper sample is 100 grams, the temperature is changed or increased by 30.0 degrees Celsius, and the specific heat of copper is 0.39 Joules per gram degrees Celsius. 
- m= 100 g 
- c= 0.39 J/g °C 
- ΔT= 30.0 °C 
Substitute the values into the formula.

Multiply the first two values. Note that the units of grams cancel. 

Multiply again, this time the units of degrees Celsius cancel. 

The copper sample absorbs <u>1170 Joules</u> of heat and <u>Choice B </u>is correct.
