The volume of the gas sample would be 477.78 mL.
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.

(2) absorb protons (4) oxidize
Answer: The nucleus of radium-226 is unstable and hence undergoes decay.
Explanation: Radium has many isotopes. One of them is which has 88 protons and 138 neutrons. It is a radioactive isotope and undergoes decay process.
This isotope undergoes alpha - decay and produces Radon-222 isotope.
Equation for alpha - decay follows:
Hence, the nucleus of radium-226 undergoes decay process.

a. NH3
b. NaNO3
c. CH3OH
d. AlCl3
Answer:
d. AlCl3
Explanation:
In AlCl₃ each Al³⁺ cation is surrounded by three Cl⁻ anion. Al³⁺ has a small ionic radius giving it a high charge density whereas Cl⁻ has a large ionic radius, low charge, and easily polarizable. Al³⁺ pulls one electron from each of the three Cl⁻ ion thus giving the Al-Cl bond a covalent character.
Polar covalent bonds are between atoms with different electronegativities, whereas nonpolar covalent bonds are between atoms with the same electronegativity.
This means that HCl is a polar covalent bond, whereas H2 is a nonpolar covalent bond.
