Answer:

102.8 kPa.

Explanation:

  • We can use the general law of ideal gas: <em>PV = nRT.</em>

where, P is the pressure of the gas in atm (P = ??? atm).  

V is the volume of the gas in L (V = 4000 mL = 6.23 L).  

n is the no. of moles of the gas in mol (n = 0.25 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),  

T is the temperature of the gas in K (T = 35ºC + 273 = 308 K).

∴ P = nRT/V = (0.25 mol)(0.0821 L.atm/mol.K)(308 K)/(6.23 L) = 1.015 atm.

  • To convert to kPa:

<em><u>multiply the pressure value by 101.325 </u></em>

∴ P = (1.0 atm)(101.325 kPa/1.0 atm) = 102.8 kPa.

Consider the process in which HClO3 is converted to HClO2. The oxidation state of oxygen remains −2, and the oxidation state of
mixas84 [53]

Answer:

Option 1, Cl is reduced and gains electrons

Explanation:

HClO₃  → HClO₂

In HClO₃, chlorine acts with +5 in the oxidation state

In HClO₂,, chlorine acts with +3 in the oxidation state.

The state has been reducted, so the Cl has been reduced. As it was reduced, it means that has won e⁻, in this case 2

Cl⁻⁵  → Cl⁻³  +  2e⁻
