At STP, 1 mole of an ideal gas occupies 22.4 liters.

At STP, 1 mole of gas occupies 22.4 L. Therefore, 4 moles occupy 4 x 22.4 L = 89.6 L.

Using the formula M = moles/volume, Volume = moles/M = 0.5 moles / 1 M = 0.5 L.

At STP, 1 mole of an ideal gas occupies 22.4 liters.

At STP (Standard Temperature and Pressure), 1 mole of an ideal gas occupies 22.4 liters.

At STP, 1 mole of gas occupies 22.4 liters.

Volume = moles x volume per mole = 4 moles x 22.4 L/mole = 89.6 L.

Volume = moles of solute / molarity = 4 moles / 2 M = 2 L.

C2H5OH + 3O2 → 2CO2 + 3H2O. 2 moles of C2H5OH produce 4 moles of CO2. Volume = 4 * 22.4 L = 89.6 L.

Volume percent = (volume of solute / total volume) x 100 = (30 mL / 150 mL) x 100 = 20%.

Volume percent = (volume of solute / total volume) × 100 = (30 mL / (30 mL + 70 mL)) × 100 = 30%.

The work done by a gas during an isothermal expansion is W = nRT ln(Vf/Vi).

The work done by an ideal gas during an isothermal expansion is W = nRT ln(Vf/Vi).

Capillarity is the phenomenon where liquid rises in a narrow tube due to surface tension.

Chemisorption is characterized by the formation of strong chemical bonds between the adsorbate and the adsorbent.

Chemisorption involves the formation of strong chemical bonds between the adsorbate and the adsorbent.

NaCl is formed by an ionic bond due to the transfer of electrons from sodium to chlorine.

Metallic bonds are formed between metal atoms, characterized by a 'sea of electrons' that are free to move.

Negative deviation from Raoult's Law occurs when strong solute-solvent interactions lower the vapor pressure more than expected.

Ethylene has sp2 hybridization due to the presence of a double bond between the carbon atoms.

The carbon atoms in ethylene undergo sp2 hybridization.

BF3 has sp2 hybridization as it has three bonding pairs and no lone pairs.

Ethylene has sp2 hybridization as each carbon atom forms three sigma bonds and one pi bond.

Methane has sp3 hybridization as it has four equivalent bonds formed by the mixing of one s and three p orbitals.

The carbon atoms in ethylene undergo sp2 hybridization, resulting in a planar structure.

H2O exhibits hydrogen bonding due to the presence of hydrogen atoms bonded to highly electronegative oxygen.

Water exhibits hydrogen bonding due to the presence of O-H bonds.

Water exhibits hydrogen bonding due to the presence of O-H bonds and the polarity of the molecule.

Water exhibits all three types of intermolecular forces, including hydrogen bonds, dipole-dipole interactions, and London dispersion forces.

The Freundlich equation describes a type of adsorption isotherm that is applicable to heterogeneous surfaces.
