The temperature is the same, so the amount of kinetic energy will also be the same.
Answer:
<h3>The answer is 8.33 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 100 g
volume = 12 mL
We have
We have the final answer as
<h3>8.33 g/mL</h3>

Answer:
B. The bonds are polar and the molecule is nonpolar.
Explanation:
Each bond in the molecule is polar, as indicated by the partial charges on the atoms of the molecule. However, the four atoms are arranged symmetrically around the central atom. In this case, the effects of the partial charges on opposite sides cancel out. As a result, the molecule as a whole is nonpolar. If exposed to an electric field, the molecule will not orient itself in any particular direction.
Answer:
D 2,2
Explanation:
We can see that there are 2 chlorines on the reactant side so there has to be a 2 on the product side
Now we have Na + Cl2 --> 2NaCl
The problem now is that there are 2 sodiums on the product side so add a 2 to the Na on the reactant side
2Na + Cl2 --> 2NaCl
Now it's balanced!
