Answer:

Argon

Explanation:

The element that would most likely be a good substitute for neon is "argon".

These two elements belong to the noble gases in Group 18(8A) of the Periodic Table. They are inert gases - they do not react chemically with other substances.

Argon, as an inert gas is often used whenever an inert atmosphere is needed. Argon is used in incandescent light bulbs. It is used to stop oxygen from corroding the filament. It is also used by welders to protect weld area.

Argon is a good substitute for neon in this context because they possess some physical properties which are similar.

In the compound h2s hydrogen has an oxidation number of 1+ and sulfur has an oxidation number of

elena-14-01-66 [18.8K]

Oxidation number is defined as the total number of electrons that are gained or lost by the atom to form a chemical bond.
the oxidation number of the compound H₂S is 0.
the sum of the oxidation numbers of the individual elements should add up to the oxidation number of the compound.

(oxidation number of H x 2 H ions) + oxidation number of S = 0
since we know the oxidation number of H, lets name the oxidation number of S = x
(+1 * 2 )+ (x) = 0
2 + x = 0
x = -2
oxidation number of S is -2

Palladium acts as a catalyst for the synthesis of carbon dioxide from carbon monoxide and molecular oxygen. Which equation below

Sonja [21]

Answer:

$C+O_2\ \overrightarrow{Pd} \ CO_2$

Explanation:

Hello!

In this case, since the catalytic reactions involve the presence of a catalyst that decrease the activation energy of the undergoing chemical reaction, when we need to include it in the chemical equation, we usually put on or underneath the reaction arrow, just as shown below:

$C+O_2\ \overrightarrow{Pd} \ CO_2$

Best regards!
