A gas has a volume of 1.75L at -23C and 150.0kPa. At what temperature would the gas occupy 1.30L at 210.0kPa?

Katen [24]

Answer:

T2 = 260 K

Explanation:

Given data:

P1 = 150.0 k Pa

T1 = (-23+ 273.15) K = 250.15 K

V1 = 1.75 L

P2 = 210.0 kPa

V2 = 1.30 L

To find:

T2 = ?

Formula:

$\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}$

$T_2 = \frac{P_2 V_2 T_1}{P_1 V_1}$

Calculation:

T2 = (210.0 kPa) x (1.30 L) x (250.15 K) / (150.0 kPa) x (1.75 L)

T2 = 260 K

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⁻
