You can increase the rate of dissolving by either: increasing surface area (powdered form of solute), increased agitation or by manipulating the temperature. The temperature method is quite tricky. Generally, solvation rate increases at higher temperatures. But there are some exceptions to the rule. However, lead chloride is not one of these. <em>Thus, increase the temperature for greater solvation rate.</em>

__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.

49 After decaying for 48 hours, l/16 of the original mass of a radioisotope sample remains unchanged. What is the half-life of t
hodyreva [135]
1/16 left would imply 4 half lives have passed (1/2 left = 1, 1/4 left = 2, 1/8 left = 3, 1/16 left = 4). So 4 half lives passed in 48 hours, meaning dividing 48 by 4 will give you the length of 1 half life. Which in this case is 12 hours.

Which of the radioactive emissions has the highest energy
hodyreva [135]
The correct answer is the gamma ray. It has the most penetration power and will pass through a number of things. Also, a gamma ray has shorter wavelength therefore higher energy from the equation, Energy = hc/wavelength.
