The answer is c and i don’t know why
Answer:
Methyl Alcohol.
Acetate
Heptane
Dioxane
Explanation:
The boiling point of liquids are measure by observing the gas pressure or vapors temperature. There are few liquids whose boiling point is difficult to measure. The gas pressure differs for every liquid. It is important to observe the vapor pressure also to identify the boiling point. The most difficult boiling point identification is for Methyl alcohol as it has ability to absorb different level of pressure.
Answer:
2.5M
Explanation:
Molarity is the measure of the molar concentration of a solution. It is calculated using the formula below:
Molarity = n/V
Where;
n = number of moles (mol)
V = volume (L)
According to the information about Calcium chloride (CaCl2) provided in this question;
n = 0.5moles
M = 0.20M
Molarity = 0.5/0.2
Molarity = 2.5M
Answer:
1 is the chemical formula for water, meaning that each of its molecules contains one oxygen and two hydrogen atoms.
2 a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
3 Chemical abbreviation for sodium chloride (table salt)
