Answer:
the substance mixture can be sperate by filtration, distillation, and freezing.
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
The result of acid on rain on buildings and bridges would be decay and rotting, the chipping and loss of cement.
Answer:
The inner diameter of the steam tube is 0.1185 m.
Explanation:

m = mass flow rate
= density of the liquid
V=specific volume =
v = velocity of the liquid
A = area of cross-section
Diameter of the cross-section = d = 2r
Given: m = 18 kg/s, v = 60 m/s,A=?, 


Area of the inner cross section = 

d = 0.1185 m
The inner diameter of the steam tube is 0.1185 m.
