Answer:
6 moles
Explanation:
You have a 1:3 ratio between nitrogen gas and hydrogen gas
Answer:
3.5 yrs
Explanation:
If a sample has decayed to 25%, this means 2 half-lives have passed. We are given this is equal to 7 yrs, and it follows that one half life is 3.5 yrs.
Answer:
a generator that allows them to convert kinetic energy into potential energy
Explanation:
Rescue workers can accomplish this by using a generator that allows them to convert kinetic energy into potential energy. Such as a crank generator, with these, they spin a crank with their hands and the generator takes that kinetic energy that is building up through the work that the rescuer is exerting and converts it to potential electric energy that can properly be used to provide energy to the batteries for their equipment. This is what is generally used for situations such as what rescuers go through when there is no electricity around.
Answer:
160.18 grams
Explanation:
You find the molar mass which is 68.16 g/mol and multiply that by the number of moles present.
