We know,
PV=nRT
203*20= n*0.0821*373
n=132.5 moles.
They give a double displacement reaction where the ions switch places and give sodium nitrate (NaNO3) and silver chloride (AgCl) as the products. Silver nitrate is also very soluble in water, but silver chloride is highly insoluble in water and will precipitate out of solution as a white solid.

Question 8, I think is C describe CR. Question 7 is Chemical reactions produce new substances
Explanation:
M/sec = 112 km / 1 hr / 1 min / 1000 meters
hr / 60 min / 60 sec / 1 km
So the answer is = 31.1 meters/sec
