The bond angle in water is approximately 104.5° due to the repulsion between the lone pairs on the oxygen atom.

Bulk modulus (K) = -ΔP / (ΔV/V) = 1000 kPa / (0.01 m³ / 1 m³) = 100000 kPa = 10000 kPa.

Using the formula C = Q/V, we have C = 6μC / 3V = 2μF.

C = Q/V = 10 × 10^-6 C / 5 V = 2 × 10^-6 F = 2 µF.

The capacitance of a spherical capacitor is given by C = 4πε₀ab/(b-a).

Xc = 1 / (2πfC) = 1 / (2π × 50 × 10 × 10^-6) = 318.31 ohms.

The standard cell potential of a Daniell cell is 1.10 V.

Using the Nernst equation, E = E° - (RT/nF)lnQ, we find E ≈ 1.0 V.

ΔS = Q/T = 2260 kJ / 373 K = 6.06 kJ/K.

In an isothermal process for an ideal gas, the temperature remains constant, which means the internal energy does not change. Therefore, ΔU = 0.

For an isothermal process, the change in internal energy ΔU = 0 for an ideal gas.

In an isothermal process for an ideal gas, the temperature remains constant, which means the internal energy does not change. Therefore, ΔU = 0.

In an isothermal process for an ideal gas, the temperature remains constant, which means the internal energy does not change. Therefore, ΔU = 0.

In an isothermal process for an ideal gas, the temperature remains constant, which means the internal energy does not change. Therefore, ΔU = 0.

For an isothermal process, the change in internal energy (ΔU) for an ideal gas is zero, as ΔU depends only on temperature.

ΔU = nCvΔT. For a monatomic gas, Cv = (3/2)R. ΔU = 1 * (3/2)(8.31 J/mol K)(600 - 300) = 900 J.

Change in internal energy (ΔU) = Q - W = 300 J - 100 J = 200 J.

Using the first law of thermodynamics, ΔU = Q - W = 200 J - 50 J = 150 J.

Using the first law of thermodynamics: ΔU = Q - W = 300 J - 100 J = 200 J.

In an isothermal process for an ideal gas, the internal energy remains constant, hence the change in internal energy is zero.

At constant volume, the change in internal energy (ΔU) is equal to the heat added (Q). Therefore, ΔU = Q.

In the conversion of glucose to ethanol, the oxidation state of carbon decreases, indicating a reduction of -1.

Manganese changes from +7 in MnO4- to +2 in Mn2+, indicating a reduction.

A neutron has no charge; it is electrically neutral.
