Answer:
It is an example of chemical reaction because carbon dioxide and water are converted into glucose and oxygen. If that makes any sense. and it is classified as endothermic because it requires the input of energy in the form of solar energy.
Explanation:
Answer:
A. the intermolecular forces are similar in both dichloromethane and iodine.
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. , if a compound is polar then it will dissolve in a polar compound only , and
if a compound is non - polar then it will dissolve in a non - polar compound only .
As,
Non polar compounds , have similar interaction , and hence gets dissolved , and similarly ,
polar compounds have similar dipole - dipole interaction , and hence gets dissolved .
From the question ,
Iodine, I₂(s), is more soluble in dichloromethane, CH₂Cl₂(l) , as both are non - polar in nature and hence due to similar interaction , are soluble .
Water is polar in nature and therefore less soluble in Iodine, I₂(s) .
Answer:
78% nitrogen
Explanation:
It has been long agreed upon that our atmosphere is highly abundant with nitrogen. Our atmosphere is composed of 78% nitrogen and then other gases follow such as 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements.
Answer:
dipole-dipole
Explanation:
Intermolecular forces exists between the molecules of a substance in a particular state of matter.
The type of intermolecular forces present in a substance is determined by the electronegativity difference between the atoms that compose the substance.
There is a non zero electronegativity difference between Br and F hence the molecule is polar and the intermolecular forces between the molecules of BrF are dipole-dipole forces.
