Chemistry
2 answers:
a_sh-v [17]3 years ago
6 0

Answer:

The characteristics are as follows:

-It is microscopic.

-It contains three sub atomic particles namely: electrons, protons and neutrons.

-It is the smallest unit of any substance (except for living bodies since smallest unit of them is cell).

-When seen from microscope atoms appear to be blur, spheres.

-They form ions(by losing or gaining electrons) and molecules(by combining with itself or other atoms).

<em><u>Hope this helps :)</u></em>

If you had 15 molecules of H2 and an unlimited supply of N2, how many
Masja [62]

Answer:

10 molecules of NH₃.

Explanation:

N₂ + 3H₂ --> 2NH₃

As the N₂ supply is unlimited, what we need to do to solve this problem is <u>convert molecules of H₂ into molecules of NH₃</u>. To do so we use the <em>stoichiometric coefficients</em> of the balanced reaction:

  • 15 molecules H₂ * \frac{2moleculesNH_3}{3moleculesH_2} = 10 molecules NH₃

10 NH₃ molecules could be prepared from 15 molecules of H₂ and unlimited N₂.

What evidence do you see that a chemical reaction is taking place when you add hydrogen peroxide to potassium ioxide??
Yuri [45]

Answer:

Bubbling/Foaming

Heat is produced

Explanation:

A chemical reaction has occurred if

1. There is a change in colour

2. Formation of a precipitate

3. Formation of a gas

4. Change in temperature

5. Change of smell

In the reaction of hydrogen peroxide and potassium iodide, the solution quickly rises which shows the formation of gas. This means it is a chemical reaction.

The beaker/test tube/whatever you used should also become warm because it is an exothermic reaction. This means its a chemical reaction
