Answer:
Atoms consist of three basic entity which can't be broken further into others namely neutron, proton, and electrons. Proton ad neutrons are kept in nucleus while electrons are in orbital, free to move in an orbital. The larger nuclear charge will make atom more stable and therefore lowers the energy. On the other hand, more electron will make atom unstable, because the energy will increase.
Thereby, option B is right choice.
Answer:
10.35 M
Explanation:
Molarity = moles solute/ L solution
18.5 mL = 0.0185 L solution
11.5 mL (1g/1mL)= 11.5 grams vinegar (1 mol / 60.052 grams) = 0.1915 mol vinegar
M = 0.1915 mol vinegar/ 0.0185 L solution = 10.35M

Boiling point: the boiling point of compounds are all different. once a compound in a mixture reaches its boiling point, it will evaporate leaving behind the other compound that is yet to reach its boiling point.
if alcohol and water are mixed together, alcohol will boil first leaving behind water, hence water and alcohol have been separated
Metal ore has other elements in it as well. Also sediment and stone might cover the ore. We don't want to have a phone with sediment on it do we? thus these few reasons are why.
Minerals, Because when wind blows everything and crushes rocks into minerals.
