Explanation:
Answer:
Molar Mass of Calcium Carbonate = 100g
given mass = 50g
Number of mole of Calcium Carbonate =50/100 = 0.5 mole
Molarity = mole per litre of volume
Molarity = 0.5 /0.25 = 2mole/litre

Answer:
Hydropower
Explanation:
I learn whenever Hydro is in a word it means water
Also in the question it is talking about water and wind, solar, nor Biomass has anything to do with water, so you can use the process of elimination and find you will only have Hydropower left.
Hope this helps
Hi There!
<span>How do the mass number and charge of a nucleus change when it emits a gamma ray?
</span><span>The charge doesn't change as a result of emitting a photon (which is what a gamma ray is). The mass does change by a small amount (due to the energy-mass equivalence relationship; a photon has no rest mass, but does have energy), but not by enough to make any real difference in the mass number.</span><span>
