Answer:

Explanation:

Most materials melt faster than most metals. For example: plastic would melt faster than iron. It just depends on the type of metal, but most non metals have lower melting points than metals.

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

Examining the equations or equilibrium constants related to a base, salt, or an acid is an indirect way to determine strength of

Gwar [14]

Answer:

1 - Weak electrolyte

2- Non electrolyte

3- Weak electrolyte

4- Strong electrolyte

Explanation:

A strong electrolyte refers to an electrolyte that decomposes completely in solution. This means that there are more charge carriers in solution when a strong electrolyte is dissolved in water. A strong electrolyte produces a strong glow. LiOH is a strong electrolyte.

A weak electrolyte is not completely dissociated in water. Only a small amount dissociates in water. HF is a weak electrolyte. A weak electrolyte does not produce a bright light.

A non-electrolyte does not dissociate in solution at all hence it does not power a bulb E.g C12H22O11.

What is the percentage of hydrogen in c2h4

jarptica [38.1K]

Ethylene- C2H4 = 85.7% Carbon and 14.3% Hydrogen

Find the atomic masses for each element and multiply it by the number of atoms in the compound, then add.

C- 12.0 * 2= 24.0

H- 1.00 * 4= 4.00

-----------------------

28.0

Take the masses for each element and divide it by the total mass. Then change the answer to get the percent.

C 24.0 / 28.0= .857 = 85.7%

H 4.00 / 28.0= .143 = 14.3%

<h3>Ethylene is 85.7% Carbon and 14.3% Hydrogen </h3>
