Answer:
Base on the properties the substances possess the substance change phase from gas to liquid.
Explanation:
Generally, matter can exist in three phase namely liquid , solid and gas. The scientist has a container with a substance inside.
At first the substance moves away from each other . This means the substance was first in the gas phase . Gas molecules, because of the energy they possess , it can move rapidly and randomly and most at times move away from each other . The gas molecules tends to fill the whole volume of the container and the shape of gases are indefinite.
Later the molecules move around each other. This is a property of a liquid . A substance in liquid phase have the ability to move freely but they stay together because of the force of attraction holding them together . The substance only have the ability to move around each other because the forces holding them together won't allow them to move apart.
Base on the properties the substances possess the substance change phase from gas to liquid.
160.0g
Mass =volume x density = 200.0 mL x 0.8 g/mL= 160.0 g
I think C-I
It can also be wrong but that’s my opinion
Answer: Option (a) is the correct answer.
Explanation:
The compound 
is tetrahedral in nature. But due to difference in electronegativity of both carbon and chlorine, chlorine is more electronegative than carbon.
Whereas carbon is more electronegative than hydrogen atom.
As a result, there will be individual bond moment which is unequal and leads to net dipole moment into the molecule.
Hence, the compound will always be polar in nature.
Thus, we can conclude that the statement molecule is always polar, describes the polarity of .
Photosynthesis is the conversion of water and carbon dioxide with the help of light energy into glucose and oxygen. Cell respiration is the conversion of glucose and oxygen into water and carbon dioxide to produce energy called ATP. The ATP created in cell respiration is used during photosynthesis to create glucose from water and carbon dioxide. This glucose can later be used in cell respiration to produce ATP, and the cycle continues.
ATP is important to the plant because ATP is the energy that allows cell respiration to start and for photosynthesis to turn water and carbon dioxide into oxygen and glucose.
