Answer;
Intermolecular forces.
Explanation;
- Melting point is the temperature at which a solid melts or a solid changes to a liquid. In liquids melting point is similar to the freezing point.
- Melting point of a substance depends on the molecular composition, force of attraction between molecules and also the presence of impurities.
- A strong force of attraction between molecules results in a higher melting point. Such that stronger intermolecular forces results to a higher melting point.
- For example, the melting point of ionic compounds is higher due to the strong electrostatic forces joining ions.

We have,
Atomic mass = no. of protons + no. of neutrons
Now, we know, protons never change.....so the only thing that changes is neutrons if we want different atomic mass.
Soooooooo,
The answer is "D. A form of an atom with a different number of neutrons"
The answer is not A. because same element with different number of electron is ion.
The answer is not B. because if it has different number of proton....it is going to be a different element. Just like our fingerprints, we can say that protons are fingerprints of element. No. of protons never change.
The answer is not C. because again talking about electrons.
Answer:
D. A form of an atom with a different number of neutrons.
Explanation:
An Isotope has an equal number of protons but different numbers of neutrons in their nuclei.

Explanation:
Number of moles consisting in a liter of solution is known as molarity.
Mathematically, Molarity = \frac{\text{no. of moles}}{\text{Volume in one liter}}[/tex]
It is given that volume is 10 liter and there is 5.0 moles of solute. Hence, we will calculate the molarity as follows.
Molarity =
=
= 0.5 mol/L
Thus, we can conclude that molarity of the given solution is 0.5 mol/L.
So let's plug in the information.
5.0 moles/10L = 0.5 M

Photosynthesis is the process in which green plants and some other organisms that makes use of the energy from the sun, converts carbon dioxide and water into glucose (a sugar) and oxygen.
Equation
6 CO2 + 6 H2O → C6H12O6 + 6 O2
The number of moles of oxygen that can be obtained from 25g of water is
= 25g/ 6( (2*1)+(16) )= 25/108
= 0.23mol
Therefore 0.23moles of water yields 0.23 moles of oxygen
