If it is assumed that there are only two isotopes then the percent abundance needs to add up to 100%
100-35= 65%
The second isotope will have a 65% abundance.

True
Explanation:
When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.
This very correct.
- When electricity is used in a sustainable way, there is little of it consumed.
- Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
- Less coal and fuel would be used and power plants do not need to produce as much electricity.
- Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
- When these appliances are turned off, less energy is in demand and less will be produced.

Answer:
Single replacement reaction
Explanation:
Answer:
B. 
Explanation:
The unit for rate is M/s while the unit for each molecule should be M. You can find the unit for k by putting the units for rate and the molecules into the equation
rate= k{X][Y]
M/s= k * 
* 
k= (M/s) / (
)
k=
You can also use this predetermined formula to solve this problem faster: k= 
Where n is the number of molecule. There are 3 molecule(2X and 1Y) so n=3, so
k=
k= 
= 
=
