Answer:
Explanation:
Remark
CH2 provides the basic structure of the hydrocarbon. It will be multiplied by some factor determined by the number of grams / mol. I will use rounded numbers because all periodic tables are slightly different.
Theoretical mass of CH2
1 C = 1 * 12 = 12
2 H= 2 * 1 = 2
Mass CH2 = 14
The multiplier for CH2
56.108 rounded = 56
Multiplier = molar mass (rounded)/Mass CH2
Multiplier = 56/14 = 4
Chemical
(CH2)_4 = C4H8
Answer: C4H8
D is the answer. in other options its just the change of state. changing of state is not a chemical thing.
H2 is colorless and odorless
NO2 is brown, pungent, and toxic
Answer:
Sugar dissolution in water is a physical change and not a chemical change because, when sugar is mixed in water, the water molecules break down the sugar molecules so, as a result sugar changes it's shape and gets dissolved in the water attaching the chain bonding between them.
Explanation:
Answer:
The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law). ... The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).
