Answer:
Six
Explanation:
Oxygen has six valence electrons in its elemental form so its formal charge is 6 – 6 = 0. Each hydrogen atom owns one electron [(2x½) = 1].
Kinetic energy is energy in motion. B, a rolling ball would be your answer because a rolling ball is energy that is moving. The rest of the answers are wrong because the actions do not use kinetic energy.
Answer:
Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
Explanation:
<span>you'll get silver chloride and potassium nitrate. Both of which are soluble, though so you get no precipitate
I thought all chlorides are soluble? </span>
Answer:
Magnesium and calcium belong to the second group i. e. alkaline earth metals. They are known as earth metals because they are extracted from the earth. They are very reactive elements. Their reactivity increases when we go from top to bottom because the outermost electrons goes farther from the nucleus i. e. atomic radius increases so less energy is needed for its removal.
