Answer:
529g/L
Explanation:
The concentration in chemistry is defined as the amount of solute in a determined amount of solution. The concentration in g/L means the amount of grams of solute (In this case, barium acetate), per liter of solution.
To solve this problem we need to find grams of solute (52.9g, already given) and the volume in liters (Converting 100mL to liters):
<em>Volume:</em>
100mL * (1L / 1000mL) = 0.100L
And concentration in g/L is:
52.9g / 0.100L =
<h3>529g/L</h3>
Answer:
a. the 3 represents the principal energy level
Explanation:
3 is the principal energy level. The p is the sublevel. 4 is the possible occupying electron.
Answer: The correct answer is option (A).
Explanation:
Oxidation : A chemical reaction in which addition of oxygen occurs or removal of hydrogen occurs is called oxidation.
Reduction:A chemical reaction in which elimination of oxygen occurs or addition of hydrogen occurs is called reduction.
In a given reaction,:
- The glucose molecule is getting oxidized into carbon-dioxide. Before oxidation in glucose molecule ratio of carbon and oxygen atom was 1:1 which changes to 1:2 after oxidation of glucose into carbon-dioxide.
Hence, is getting oxidized.
- The oxygen molecule is reduced because addition of hydrogen atoms are taking place in oxygen molecules which gives water after reduction.
Hence, is getting reduced.
So, correct answer is option (A).
13000 liters, 0.000012 cm3 or ml or cc
Answer:
no
Explanation:
a cell is something that either stays inside of something or is a individual floating object and it does not compare to bigger sized materials
