Q = m * L = 1000 g * 2260 J/g = 2260000 J.

To round 0.0001234 to two significant figures, we look at the first two non-zero digits (1 and 2) and round up, resulting in 0.00013.

To round 0.05060 to three significant figures, we keep the first three significant digits (5, 0, and 6), resulting in 0.0506.

The compound has a carboxylic acid group and a total of 5 carbons with two methyl groups on the third carbon, making it 3,3-Dimethylbutanoic acid.

The longest chain has 5 carbons, and there are two methyl groups on the third carbon, making it 3,3-Dimethylpentane.

Strong acid and strong base neutralize each other, resulting in a neutral solution with pH = 7.

Using the formula Ka = [H+]^2 / [HA], where [H+] = 10^(-4) M and [HA] = 0.1 M, we find Ka = (10^-4)^2 / 0.1 = 1 x 10^-5.

Vapor pressure lowering = (n_solute / n_solvent) * P°_solvent = (0.5 / 55.5) * 23.76 = 1.88 mmHg

At STP, 1 mole of gas occupies 22.4 L. Therefore, the molar volume is 22.4 L.

Concentration (M) = moles of solute / liters of solution = 0.5 moles / 1 L = 0.5 M.

Concentration (M) = moles of solute / liters of solution = 0.5 moles / 1 L = 0.5 M.

Molarity (M) = moles of solute / liters of solution = 0.5 moles / 1 L = 0.5 M.

Q = m*c*ΔT = 1000 g * 4.2 J/g°C * (100°C - 20°C) = 4200 J.

Using the dilution formula M1V1 = M2V2, we have 2 M * 1 L = M2 * 3 L, thus M2 = 2/3 = 0.67 M.

Using the dilution formula M1V1 = M2V2, we have 3 M × 1 L = M2 × 2 L. Thus, M2 = 1.5 M.
