Hydrogen gas
Explanation:
Expression:
CO₂ + H₂ → CO + H₂O
Hydrogen gas in this reaction is oxidized in the reaction.
In this manner, it is the reducing agent in the reaction.
A reducing agent is the specie in a chemical reaction that undergoes the process of oxidation.
It is marked by:
- Addition of oxygen to a specie
- Removal of hydrogen from a specie
- Loss of electron by an atom
- Increase in oxidation number
- Increase in number of electronegative atoms surrounding a specie.
Here we see that H₂ fits this criteria perfectly well.
CO₂ is the one reduced.

<span>Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different
number of neutrons. They differ in the number of neutrons that is why
they also differ in mass numbers. Since they have the same number of
protons, they have the same atomic number.
For instance, when the
nucleus of the isotope with a 68.926 amu, there are 30 protons and 39
neutrons in the nucleus. The best example for this is Zn (zinc-69
isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu
respectively.

Tornados could be possible or storms
Explanation:
The answer is A carbon monoxide.
Answer:
- <em><u>Option A. </u></em><u><em>2KClO₃ → 2KCl + 3O₂</em></u>
Explanation:
There are five basic general types of chemical reactions:
- Synthesis or combination reaction
- Single replacement reactions
- Double replacement reactions
The given reactions are:
- <u>2KClO₃ → 2KCl + 3O₂</u>
Which is, indeed, a decomposition reaction because the reactant, KClO₃, is a single substance that undergoes a reaction in which it yields two new substances, known as products: KCl and O₂.
- <u>4Na + O₂ → 2Na₂O</u> is a synthesis or combination reaction because two reactants, Na and O₂, combine for the formation of one single new product, Na₂O.
- <u>ZnS + 3 O₂ → 2ZnO + 2SO₂ </u>is a single replacement reaction because oxygen is replacing Zn and S in ZnS to form ZnO and plus SO₂.
- <u>2NaBr + CaF₂ → 2NaF + CaBr₂ </u>is a double replacement reaction because two ions (Br⁻ from NaBr and F⁻ from CaF₂) are exchanging places with other two ions (Na⁺ from NaBr and Ca²⁺ from CaF₂) two form two new ionic compounds (NaF and CaBr₂).
