A gas occupies 11.2 L at a pressure of 35.0 mm . What is the volume of the gas if it is Increased to a pressure of 64.0 mm Hg?

Alchen [17]

Explanation:

$from \: boyle's \: law \\ P _{1} V _{1} = P _{2} V _{2} \\ 35 \times 11.2 = 64 \times V _{2} \\ V _{2} = \frac{35 \times 11.2}{64} \\ V _{2} = 6.125 \: L$

galvanic cell is powered by the following redox reaction: (g) (aq) (l)(aq) (s) (aq) Answer the following questions about this ce

kotykmax [81]

Answer:

Explanation:

1. the 1/2 reaction that occurs at the cathode

3Cl2(g) +6e^- -------------> 6Cl^- (aq)

2 the 1/2 reaction that occurs at the anode

2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-

E0 = -0.59v

3Cl2(g) +6e^- -------------> 6Cl^- (aq)

E0 = 1.39v

3Cl2 (g) + 2MnO2 (s) + 8OH^(−) (aq)---------> 6Cl^(−) (aq) + 2MnO4^(−) (aq) + 4H2O (l)

E0cell = 0.80v
