Answer: because they make there hypothesis before they actually get the facts.

Explanation:

Final answer:

The volume of the gas sample would be 477.78 mL.

Explanation:

The student is asking about the change in volume of a gas sample when the pressure is increased. This can be solved using Boyle's law, which states that the pressure and volume of a gas are inversely proportional at constant temperature. The equation for Boyle's law is: P1 * V1 = P2 * V2

We are given the initial conditions: T1 = 25.2°C, V1 = 536 mL, and P1 = 0.838 atm. We need to find V2 when P2 = 0.937 atm. Using the Boyle's law equation, the volume can be calculated as: V2 = (P1 * V1) / P2

Plugging in the values, we get: V2 = (0.838 atm * 536 mL) / 0.937 atm = 477.78 mL

Therefore, the volume of the gas sample would be 477.78 mL (Option A) when the pressure is increased to 0.937 atm.

Answer;

(4) the total number of protons and the total number of electrons in the atom

Explanation;

-Atomic number is the number of protons in the nucleus of an atom. An atom is made up of energy shells and the central nucleus. The energy shells contains electrons that are negatively charged while the nucleus contains protons (positively charged) and neutrons (neutral).

-In a neutral atom, the number of protons and electrons are equal, thus the atomic number would indicate the number of electron and protons in an atom. The sum of protons and neutrons on the other hand gives the mass number.
