A0.00100 mol sample of ca(oh)2 requires 25.00 ml of aqueous hcl for neutralization according to the reaction below. what is the concentration of the hcl? ca(oh)2(s) + 2hcl(aq) --> cacl2(aq) + h2o(l)

0.08 mol/L is the concentration of the HCl solution.

Explanation:

Moles of calcium = 0.00100 mol

According to reaction ,1 mole of calcium hydroxide reacts with 2 moles of HCl.

Then 0.00100 mole of calcium hydroxide will react with:

Moles of HCl = 0.00200 mol

Volume of solution = 25.00 mL = 0.025 L

Concentration of HCl solution:

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
