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.
Activation energy is the energy required by reactants to undergo chemical reaction and given products
Every reactant has some internal energy (sum of all kind of energy like kinetic energy, potential energy, mechanical energy, chemical energy etc). It needs some extra energy to undergo chemical reaction which is activation energy
All kinds of reaction whether exothermic or endothermic needs activation energy
Threshold energy = internal energy + activation energy
There are 0.501 moles in 60.66g of CF2Cl2
Explanation:
An ionic equation will be the one in which all the participating species will be present as ions.
The given reaction will be as follows.
Balancing this equation by multiplying 
by 2 and 
by 3 on reactant side. Whereas multiply KBr by 6 on product side.
Hence, the net ionic equation will be as follows.
As both 
and 
are spectator ions. Hence, the net ionic equation will be as follows.
