Known :
r = 6 in
h = 11 in
Asked :
Volume = ...?
Answer :
V = πr²h
= 3.14 × 6² × 11
= 3.14 × 36 × 11
= 3.14 × 396
= <u>1</u><u>,</u><u>2</u><u>4</u><u>3</u><u>.</u><u>4</u><u>4</u><u> </u><u>in³</u>
So, the volume is 1,243.44 in³ (2nd choice)

Answer:
A) oxidizing agent is SO2
B) NaClO is the oxidizing agent
Explanation:
A) This is a redox reaction in which oxidation and reduction occur simultaneously.
Thus, in 2H2S(g) + SO2(g) -> 2H2O(l) + 3S(s);
H2S is reduced as follows;
H2S → S + 2H+ + 2e−
We can see that SO2 has been reduced while H2S gets oxidized since it has changed state from - 2 to 0 . Thus sulphur dioxide is the oxidizing agent.
B) SO2(g) + H2O(l) + NaClO(aq) -> NaCl(aq) + H2SO4(aq)
In this, SO2 undergoes oxidation and NaClO is the oxidizing agent
They generally have 4 - 7 electrons in their outer shell.
