<h3><u>Answer;</u></h3>

A; nuclear fission

<h3><u>Explanation</u>;</h3>
  • Nuclear fission is a process by which a large nucleus is split into two smaller nuclei, or fission fragments. It takes place after the nucleus absorbs a neutron that usually is a product of another atom's radioactive decay.
  • A common fission reaction bombards uranium-235 with a single neutron. This creates a uranium-236 atom which is unstable. Its nucleus tends to split into more stable products like Krypton-90 & Barium-143.
  • If you compare the masses before and after reaction, notice that Kr-90 + Ba-143 only = 233. But they were produced from U-236. This is because 3 neutrons were also released.

Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider a mixture of six nitrogen molecules and six hydrogen molec
Nezavi [6.7K]

Answer:

a)  No molecules of hydrogen

b) four molecules of ammonia

c) four left molecules of nitrogen.

Explanation:

The balanced reaction between nitrogen and hydrogen molecules to give ammonia molecules is:

N_{2}(g)+3H_{2}(g) -->2NH_{3}

Thus one molecule of nitrogen will react with three molecules of hydrogen to give two molecules of ammonia.

We have six molecules of each nitrogen and hydrogen in the closed container and they undergo complete reaction it means the limiting reagent is hydrogen. For six molecules of nitrogen, eighteen molecules of hydrogen will be required.

So six molecules of hydrogen will react with two molecules of nitrogen to give four molecules of ammonia.

The product mixture will have

a) No molecules of hydrogen

b) four molecules of ammonia

c) four left molecules of nitrogen.

Do non metals have lower melting points than metals?
yarga [219]

Yes,according to healthline.com non metals have lower melting points than metals.See metal is extremely hard to melt that would need very hot fire or lava,lava preferbally.So yes non metals have lower melting points than metals.

Hope this helps!Branliest would be appreciated:D
