Chemistry
1 answer:
Mariana [72]3 years ago
3 0

Answer:

If your asking for the definition of opinion, it's the belief or judgement of how you see a certain situation, example

  • Ice cream is the best dessert

That's an opinion since it is not a solid statement that everybody in the world would agree on. So it's how you think of something.

Hope this helped and if it did then mark as brainliest! Appreciate it.

Which salt is produced when NH4OH Reacts with HNO3
borishaifa [10]

Explanation:

When an acid reacts with a base then it results in the formation of salt and water.

HNO_{3} is an acid and NH_{4}OH is a base thus, when we dissolve ammonium hydroxide in nitric acid then it results in the formation of ammonium nitrate and water.

The reaction is as follows.

 NH_{4}OH + HNO_{3} \rightarrow NH_{4}NO_{3} + H_{2}O

Hence, there will be formation of ammonium nitrate (NH_{4}NO_{3}) salt.
