Answer : The volume of gas sample will be, 9.93 L
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles of gas.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Now put all the given values in above equation, we get:
Therefore, the volume of gas sample will be, 9.93 L
Because they usually are weak.

Explanation:
The charge of a helium atom is zero
It is neutral because
The number of unit negative charges = number of unit positive charges
One unit negative charge = -1.6 x 10^(-19) which is basically the charge of an electron
One unit positive charge = +1.6 x 10^(-19) which is basically the charge of a proton
A helium atom has 2 protons and 2 electrons, so it is neutral
NOTE: an alpha-particle (He2+) is a charged helium atom it has 2 protons and 0 electrons. Charge of an alpha particle = +3.2 x 10^(-19).
Answer:
Explanation:
Salt water intrusion can cause the <u><em>fresh</em></u> water in wells to become contaminated with<u><em> salt</em></u>water.
Answer:
Dispersion forces- Xe, CH4
Dipole-dipole forces-CHCl3
Hydrogen Bonding-HBr, NH3, CH3COOH
Explanation:
Gases and nonpolar molecules posses only dispersion forces. Polar covalent compounds posses dipole- dipole forces. When hydrogen is bonded to a highly electronegative atom, hydrogen bonding results. These account for the arrangement of answers above.
