Answer:
The solid crystal will precipitate.
Explanation:
Solubility indicates how much solid can be in solution without it precipitating and depends on the temperature for most salts or compounds, increasing as the temperature rises.
Therefore, if the beaker is heated, more solid will remain in solution, in this case until saturation (the maximum amount of the solid that can be in solution without it precipitating).
As the temperature drops, the solubility drops, therefore any amount of solid that is added additionally will precipitate.
Nitrogen
Explanation:
Adding one proton to a carbon atom makes Nitrogen.
A quick introspection on atoms:
- An atom is made up of three fundamental particles.
- They are protons, neutrons and electrons.
- The protons are positively charged and the neutrons do not carry any charges.
- Electrons are negatively charged.
The difference between an atom and another is the number of protons in them. This is the atomic number.
The periodic table of element is a list of elements arranged based on the number of protons they have. Every element on the table has unique number of protons which makes it differ from another.
- Atoms do not readily lose their protons because they are held by nuclear forces in the nucleus of an atom.
When an element gains a proton, it becomes another element.
Carbon has proton number of 6
If a proton is added to it, it becomes 7
This is the proton or atomic number of nitrogen.

<u>Answer:</u> The correct answer is 2.24 MeV.
<u>Explanation:</u>
The chemical reaction for the formation of deuterium from proton and neutron follows:
We are given:
Mass of 
= 1.00784 u
Mass of 
= 1.008665 u
Mass of 
= 2.014102 u
To calculate the mass defect, we use the equation:
To calculate the energy released, we use the equation:
(Conversion factor: 
)
Hence, the energy released in the given nuclear reaction is 2.24 MeV.
