The answer i got is 2.95 g Co
Answer: b. The waste generated is hazardous and must be disposed of.
c. Nuclear material can be spilled into the ocean if reactors are near the coast.
d. A large amount of cold water is generated, which must be stored somewhere.
Explanation:
The main environmental costs for produced during the nuclear power plant consists of procurement of fuel and the thermal load is also produced with cold water discharge in the sea. This can contaminate the sea, hence, must be stored somewhere. The nuclear waste consists of radioactive substances which are hazardous for the environment. The nuclear based electricity does not produce carbon dioxide.

1. Remember (sum of products) - (sum of reactants)
So ΔHrxn = 2 ΔHf [H2(g)] + ΔHf [Ca(OH)2(s)] - 2 ΔHf [H2O(l)] - ΔHf [Ca(s)]
= 2*0 + -986.09 kJ/mol - 2*(-285.8 kJ/mol) - 0
Do the math and you'll have the answer. BTW the ΔHf [H2(g)] and ΔHf
[Ca(s)] were 0 because these are elements in their standard states.

Answer:
it is an ideal gas because all of the substances that it has are good for us and won't affect us in any way
Answer: Option (B) is the correct answer.
Explanation:
When we heat food in a microwave then the electrical energy of microwave produces microwaves which are also part of electromagnetic spectrum.
These microwaves are absorbed by food and as a result microwaves change into heat energy. Therefore, food becomes hot.
Thus, we can conclude that to cook food, a microwave oven converts electrical energy into heat energy.
