The substance you would expect to have a low melting point would be carbon dioxide, so the correct answer would be A
Well if too much weathering occurs, it might break off parts of the cliff and be dangerous to humans, or animals.
Answer:
The kilogram is the standard unit of mass.
B). light energy is not required to proceed
Explanation:
In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.
- During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
- During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
- The cycle is also known as dark reactions.
- It is at this stage that carbon dioxide combines with water to form glucose.
- The reaction is initiated with light energy which produces NADPH and ATP.
- The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.

From the Graham's law of effusion;
R1/R2 = √MM2/√MM1
Molar mass of chlorine gas is 71
Therefore;
1.87= √ 71 /√mm1
= 1.87² = 71/mm1
mm1 = 71/1.87²
= 71/3.4969
= 20.3
Thus, the molar mass of the other gas is 20.3 , and i think the gas is neon
