Answer:
Am I the bad guy for killing my fish, let me explain?
Explanation:
The fish said a bad word that was incredibly inappropriate, so then I told him to never say that again. He responds with, "No, I CAN SAY WHATEVER I WANT." After that I told him to not yell at me and then I killed him, remember he's a fish (GoldFISH).
To solve this problem, let us all convert the mass of
each element into number of moles using the formula:
moles = mass / molar mass
Where,
molar mass K = 39.10 g / mol
<span>molar mass Cl = 35.45 g / mol</span>
molar mass O = 16 g / mol
<span>and mass O = 13 g – 4.15 g
– 3.76 g = 5.09 g</span>
moles K = 4.15
g / (39.10 g / mol) = 0.106 mol
<span>moles Cl = 3.76 g / (35.45 g / mol) = 0.106 mol</span>
moles O = 5.09 g / (16 g /
mol) = 0.318 mol
The ratio becomes:
0.106 K: 0.106 Cl: 0.318 O
We divide all numbers with
the smallest number, in this case 0.106. This becomes:
K: Cl: 3O
Therefore the empirical formula
is:
Answer: C. Although nuclear power can provide cheaper electricity while producing less pollution, the risk of nuclear waste and the potential for a disaster should be considered.
Explanation:
The nuclear power plants uses the radiation energy to cause fission of heavy atoms. The energy is produced in the form of thermal energy. The nuclear power plants do not produce, carbon dioxide and other pollutants in the environment, thus these do not cause pollution in the environment. The radioactive waste are highly mutagenic in nature this causes deadly mutations in the living beings. Thus a risk is associated with the generation of energy in the nuclear power plant.
