Answer:
C
Explanation:
Think about it. If you accelerate, you go faster. This means you change speed.
N2 is non-polar molecules,
NO2 is polar molecules that have slightly positive charge on N and slightly negative on O, so <span>intermolecular forces are stronger in NO2</span>
Answer:
i would say 10, so the anser is A.
Explanation:
because there are the same number of protons and electrons, therefore for a regular O, you are supposed to have only 8 protons, but it is charged, thus, whatever the charge is will be taken into consideration into how much the proton and electron doe it have. Thus, for this case, it has 10, because the charge is negative and you have 8 electron plus 2 = 10.
