__is when two genetic sequences bind together because of the hydrogen bonds that form between the base pairs ​
Anettt [7]

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.

A compound is analyzed and found to be 50% sulfur and 50% oxygen. If the total amount of the sulfur oxide is 12.5 g, how many gr
il63 [147K]

Answer:

25.0g is the mass of sulfur

Explanation:

The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.

To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:

<em>Moles O = Moles S:</em>

12.5g O * (1mol / 16g) = 0.781 moles

<em>Mass S:</em>

0.781 moles * (32g / mol) =

<h3>25.0g is the mass of sulfur</h3>
