Can any Top Contributor Help Me out with these Following questions PLease.?

Question

1*Which word describes best the change when ammonium nitrate dissolve in water?

Electrolysis , Endothermic or Exothermic

2*A student wants to make a reaction faster.

what would make the reaction faster

Use bigger pieces of Zinc

Or Use a more concentrated Acid Or

Decrease the temperature

3*What is the name of the raw meterial from which nitrogen is obtained.

AIR OR METHANE OR OIL OR WATER

4*Some ammonia produced is nuetralized by nitric acid to make a salt this salt is used as a fertilizer

NAME THE SALT PRODUCED WHEN AMMONIA IS NEUTRILIZED WITH NITRIC ACID.

iS IT A)ammonia nitrate

b ammonia nitride

c ammonium nitrate

d ammonium nitride

THANK YOU THE END

Answer 1

1) endothermic

2) what reaction are you talking about?? Nevertheless, without knowing the reaction, I would say that a and c are unlikely to work so the answer is likely to be use a more concentrated acid.

3) Air

4) ammonium nitrate

Answer 2

i'm not a top contributor but i'll try my best to answer this. you should not be demanding with who must answer your questions.

1. endothermic

2. more concentrated acid

3. air

4.ammonium nitrate

Answer 3

When you dissolve ammonium nitrate in water, the temperature drops. That makes it an endothermic change.

To speed up a reaction, you can do a number of things: increase surface area, use more concentrated reagents, alter temperature and/or pressure (mainly for equilibrium reactions), add a catalyst... I guess you mean Zn + acid → Zn salt + H2 gas. Here, using larger pieces of zinc will decrease the surface area, lowering the rate. Use a more concentrated acid.

Air contains almost 79% extractable N2, so air is the prime raw material. The rest contain either no nitrogen, or only traces.

Ammonia forms ammonium salts, and salts of nitric acid are called nitrates. So it is ammonium nitrate, NH4NO3.

Answer 4

Why dont you do your own homework? The questions require research.I suggest you use the internet eg Google to get an understanding of the terms eg endothermic,rates of reaction,neutralisation etc
