Answer:
NaCl.
Explanation:
In the solution, ZnSe ionizes to 
and 
. Following reaction represents the ionization of ZnSe in solution -
⇄ 
As we want to increase the solubility of ZnSe, we must decrease the concentration of dissociated ions so that the reaction continues to forward direction.
If we add NaCl to this solution, then we have 
and 
in the solution which will be formed by the ionization of NaCl.
Now, in the solution will react with two ions to form 
as follows -
⇄
Due to this reaction the concentration of will decrease in the solution and more ZnSe can be soluble in the solution.
One
Balance the Equation.
This has been done for you or it is given. Anyway this step is finished, but it must always be done.
Two
Find the molar mass of C6H12O6
6C = 6 * 12 = 72
12H = 12*1 = 12
CO = 6 * 16 = 96
Mol Mass = 180 grams / mol
Three
Find the mols of C6H12O6
n = ???
Molar Mass = 180 grams / mol
given mass = 13.2 grams.
n = given mass / molar mass
n = 13.2 / 180
n = 0.07333333 mols.
Four
Find the mols CO2
1 mol C6H12O6 will produce 6 mols CO2
0.0733333 mols will produce x
1/0.073333 = 6/x Cross multiply
x = 0.073333 * 6
x = 0.4399 moles.
Five
Find the volume given the conditions for temperature and pressure are STP conditions.
PV = nRT
R = 0.082057
n = 0.43999
P = 1 atmosphere
T = 0 + 273 = 273
V = ???
1 * V = 0.43999 * 082057 * 273
V = 10.2 L
Answer: B
Note if you give out Brainly awards I'd sure appreciate one. This was a lot of typing
Answer:DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Explanation:
Beriberi is a vitamin deficiency disease caused by a deficiency in *THIAMINE* as this isa *THIAMINE*
precursor to the coenzyme which is used in the *PYRUVATE*reactions of the citrate cycle. Brown rice, in which the bran of the rice remains, is considered more nutritious than white rice, in part because this vitamin is not removed. Beriberi can also be caused by consuming foods that contain high levels of *THIAMINASE*, such as uncooked fish and silkworms.
Beriberi is a disease which is also called thiamine deficiency is caused as a result of deficiency in by a vitamin B-1. Beriberi disease can occur in two ways, as wet beriberi or dry beriberi.
Dry beriberi usually attack the nerves and later damage it and which lead to weakening of muscle and eventually paralysis of muscle.
On the other hand, Wet beriberi attack the heart as well as the circulatory system, which can result to heart failure in extreme condition.
