what are the advantages and disadvantages of using renewable and nonrenewable energy resources? Use evidence from the lesson and scientific reasoning to support your answer ??

They'll never run out. They don't damage our planet. They're low-maintenance energy sources.They're good news for regional areas.

Unreliable weather can affect energy supply. 

Hydro generators need enough rain to fill dams for their supply of flowing water.Wind turbines need wind to turn their blades. Solar panels need clear skies and sunshine to get the heat needed to generate electricity.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
