Explanation

Ernest Rutherford (1911) proposed the nuclear model of the atom with a dense central nucleus.

This came after his gold foil experiment, which showed atoms have a small, positively charged core.

He was a New Zealand-born British physicist who came to be known as the father of nuclear physics.

Explanation

ATP (Adenosine Triphosphate) is the direct source of energy in living bodies.

Glucose and fatty acids provide energy indirectly, but ATP is the immediate usable energy currency.

Explanation

Water (H₂O) is an inorganic compound as it does not contain carbon-hydrogen (C-H) bonds.

Alcohol, chloroform, and ethane are organic compounds because they contain carbon atoms bonded to hydrogen.

Explanation

Absolute temperature (0 K) is the theoretical lowest temperature.

At this point, all molecular motion stops, and the system has minimum internal energy.

Explanation

Molarity is calculated by dividing the number of moles of solute by the volume of solution in liters. 

Therefore, the molarity of pure water is approximately 55.56 moles/L, or approximately 55.5 M.

Explanation

The formula for sulfuric acid is H2SO4.

It indicating that one molecule contains two hydrogen atoms, one sulfur atom, and four oxygen atoms.

Explanation
