Butane is a common fuel used in cigarette lighters and camping stoves. Normally supplied in metal containers under pressure, the
klasskru [66]

Pressure of Butane in the container at 135°C = 1.07 atm

Given:

The H°vap of butane is 24.3 kJ/mol.

starting out at 25 °C

Temperature at the end: 135 °C

2.3 atm of pressure

To Find:

The container's pressure

The perpendicular force per unit area, also known as the stress at a point within a confined fluid, is known as pressure in the physical sciences.

Equation of Clausius-Clapeyron

P2 = 1.07 atm and ln (P2/2.3 atm)

= - 24.3*110/8.31

The pressure in the container at 135°C (ΔH°vap ) is 1.07 atm

Which of the following statements best compares the pH value of H3PO4 and HCl?
wel

Answer:

Option B. Both have a pH less than 7, but H3PO4 has a lower pH than HCl

Explanation:

Those are acid, so the pH would be < 7.

H₃PO₄ is a weak acid with 3 dissociations

HCl is a strong acid.

pH depends on [H]⁺

H₃PO₄  →  3H⁺  +  PO₄⁻³

HCl →  H⁺  +  Cl⁻

If both acid, have the same concentration, [H⁺]H₃PO₄ > [H⁺]HCl, that's why the pH from the phosphoric will be lower.
