Electrons are only
about 0.054% as massive as neutrons and protons are only 99.86% as massive as
the neutrons. The mass of the Proton is 1.67 x 10^-27 kg and the mass of the electron
is 9.11 x 10^-31 kg. The mass of the electron is so much lighter than the mass
of the proton.

Answer:
A
Explanation:
The molecule with the strongest intramolecular bond is HF. Hydrogen fluoride is the answer due to the strong and highly electronegative nature of Fluorine.
- Fluorine is the most electronegative element in nature.
- When it combines with other substances, due to its electronegative property, it draws most of the electrons closest to itself in the bond.
- This tendency and ability makes the shared electrons closer the fluorine in the bond.
- The strong polarization that ensues confers a very strong covalent bond pair on the bond formed.
Answer:
Firstly, Let's experiment this !
Experiment 1 :
159.446g - 124.966g = 34.48g
34.48g = The mass of Mineral oil.
The density of the mineral oil = M/V = 34.48g/40mL = 0.862g/cm³.
Experiment 2 :
124.966 + 18.173 = 143.139 = The mass of solid + cylinder.
124.966 + 50.952 = 175.918 = The mass of solid + cylinder + Mineral water.
175.918 - 143.139 = 32.779 = The mass of added mineral oil.
Explanation:
Now we have to find the volume of the added mineral oil using the density from experiment 1.
V = 32.779g/0.862g/cm³ = 38.02668213mL
Since we found the volume of the solid, we then have to subtract the added mineral oil volume from the total volume from experiment 1.
Volume of solid = 40-38.02668213 = 1.97331787mL
Density of solid = 18.713g/1.97331787mL = 9.483013499g/cm^3
1.97331787 = (4/3)(3.14)r³
1.97331787*(3/4)(3.14) = .4713338861
.4713338861 = r
³
r = 0.7782328425158433
r = 0.78
Now that's our final answer ! r = 0.78
1, When temperature is increased the volume will also increase. this is because the particles will gain kinetic energy and bombard the walls of the container of the gas at a higher frequency, therefore, for the pressure to remain constant as per Charles' law, the volume will have to increase so that the rate of bombardment remains constant. This is explained by the Charles law which states that the volume of a gas is directly proportional to the absolute temperature provided pressure remains constant.
2. When temperature is Decreased the volume will also Decrease. this is because the particles will loose kinetic energy and bombard the walls of the container of the gas less frequently, therefore, for the pressure to remain constant as per Charles' law, the volume will have to reduce so that the rate of bombardment remains constant. This is explained by the Charles law which states that the volume of a gas is directly proportional to the absolute temperature provided pressure remains constant.
3. When temperature is increased the pressure will increase. This is because the gas particles gain kinetic energy and bombard the walls of the container more frequently. this is according to Pressure law which states that for a constant volume of a gas the pressure is directly proportional to absolute temperature
4. When temperature is decreased, pressure will decrease, This is because the gas particles lose kinetic energy and bombard the walls of the container less frequently. this is according to Pressure law which states that for a constant volume of a gas the pressure is directly proportional to absolute temperature
5. When particles are added, pressure will increase. This is because the bombardment per unit area also increases. Boyles law explains this, that at fixed temperature the volume of a gas is inversely proportional to the pressure.
6. When particles are removed, the pressure will decrease. This is because the bombardment per unit area also decreases. Boyle's law explains this, that at fixed temperature the volume of a gas is inversely proportional to the pressure.
