Explanation:
it's one mole because the atomic mass is treated as molar mass and the atomic mass of strontium is 87.62 grams/mol
The correct answer is C.
On the left:
2 carbon+ 2 oxygen+ 2 oxygen
On the right:
2 carbon+ 4 oxygen (remember to multiply the coefficient and subscript)
B.)<span>A doctor would use technetium-99m because a short half-life indicates a quick measurement, and a geologist would use rubidium-87 because a longer half-life means that there is a longer time to measure old rock. </span>
Answer:
I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
