Answer:

The correct answer is - temperature, state of molecules, and the number of molecules.

Explanation:

The total thermal energy of a system or the total internal energy of a system solely depends on three major aspects of the system's or objects that are the number of molecules or atoms in the system, the temperature of the system, and the state or arrangement of the molecules of the system. More the molecules or atoms present in a system at a particular temperature higher the total thermal energy the system has.

Thus, the correct answer is - temperature, state of molecules, and the number of molecules.

Write the balanced equation for the reaction of hydrogen chloride with sodium hydrogen carbonate to give sodium chloride, carbon

marusya05 [52]

These are the formulas of each compound mentioned:

1) Hydrogen chloride: HCl

2) Sodium hydrogen carbonate: NaHCO3 , this is also known as sodium bicarbonate. The number 3 to the right of O is a subscript.

3) Sodium chloride: NaCl

4) Carbon dioxide: CO2. This is also known as carbon anhydride. The number 2 to the right of O is a subscript.

5) Water: H2O. The number 2 to the right of H is a subscript.

The the chemical equation is:

HCl + NaHCO3 → NaCl + CO2 + H2O

Check the balance

element left side right side
H 1+1 = 2 2
Cl 1 1
Na 1 1
C 1 1
O 3 2+1 = 3

Then, given that the number of each element on the left side is equal to the number of elements in the right side, the equation is balanced.

Atomic physics is the field of physics that studies atoms.
In 1913, Niels Bohr made a theory for the hydrogen atom based on quantum theory which states that energy can only be transferred in certain quantities. Electrons move around the nucleus but only in fixed orbits. When an atom jumps from one orbit to another with lower energy level, a light quantum is emitted as a result.
