The correct statements which are true for the reactions in the Sun are that are fusion reactions and reactions occur because of very high temperatures.
<h3>What is nuclear fusion?</h3>
Nuclear fusion reactions are those reactions in which two species reacts with each other for the formation of new specie.
In the core of the sun, nuclear fusion of hydrogen atoms occur for the formation of helium molecules in the presence of high temperature.
Hence, the correct statements are they are fusion reactions and reactions occur because of very high temperatures.

Answer:
Intramolecular forces
Explanation:
Intramolecular forces are stronger than intermolecular forces, because the attractions that hold compounds together are stronger than the attractions between molecules.
The pressure of the air is 40000N/m².
To calculate the pressure of the plane, we use the formula below.
Formula:
- P = F/A................. Equation 1
Where:
- P = Pressure of the air
- F = Force on the plane
- A = Total surface area of the plane.
From the question,
Given:
Substitute these values into equation 1
- P = 8000000/200
- P = 40000 N/m².
Hence, The pressure of the air is 40000N/m².

Answer:
All statements are true
Explanation:
Arrhenius theory:-
The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.
According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, 
.
Hence, statement 1 is correct.
Bronsted-Lowry base is the specie which accepts the proton form the medium. For example, Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-
Hence, statement 2 is correct.
Acetic acid will dissociate as:-
Hence, statement 3 is also correct.
Volume would be 6.79792764 cm³. Just divide 131.2 by 19.3
ρ=Mass/Volume
Volume= mass/density
