Molarity= moles/Volume => 9/15 = 0.6 mol/L
Answer:
I would recommend lemon Juice
Explanation:
oxidation is a chemical process that occurs in the presence of oxygen and moisture. this process cause fruits to change in color and have an undesired flavor. hence an anti-oxidant like lemon juice when added to such fruits can prevent their oxidation over a long period of time. lemon juice (ascorbic acid) is a natural antioxidant and find great use in the food and beverage industry for preservation.

Answer:
CH2N2
Explanation:
To find the molecular formula, we must first find the empirical formula as follows:
28.57% C - 28.57g of Carbon
4.80% H - 4.80g of Hydrogen
66.64% N - 66.64g of Nitrogen
Next, we convert this mass values to mole by dividing by their respective atomic mass.
C = 28.57/12 = 2.38mol
H = 4.80/1 = 4.80mol
N = 66.64/14 = 4.76mol
Next, we divide each mole value by the smallest mole value (2.38mol)
C = 2.38mol ÷ 2.38 = 1
H = 4.80mol ÷ 2.38 = 2.01
N = 4.76mol ÷ 2.38 = 2
The empirical ratio of C, H and N is therefore 1:2:2. Hence, the empirical formula is CH2N2
To calculate the molecular formula;
(CH2N2)n = 42.04 g/mol
{12 + 1(2) + 14(2)}n = 42.04
{12 + 2 + 28}n = 42.04
{42}n = 42.04
n = 42.04/42
n = 1.00009
Since n = 1, molecular formula is CH2N2
Answer:
The answer to your question is: letter D
Explanation:
A. a motile archaea Archea don't have peroxisomes then this option is wrong.
B. a nonmotile eukaryote The new organism has flagella then it can move, so this option is wrong.
C. a motile bacterium Bacterium don't have peroxisomes so this option is wrong.
D. a motile eukaryote This is the correct option because an eukaryote can have all the characteristics described.
