Ferrosoferric oxide and hydrogen gas are the products of this reaction.

<h3><u>Explanation:</u></h3>

Iron is the metallic element with the atomic number 26. It has a valency of both 2 and 3 which forms two types of oxide - ferrous oxide and ferric oxide.

Iron reacts with water with a metal and acid reaction, which forms both the iron oxide and evolves hydrogen gas. The hydrogen gas escapes the system and the mixture of iron oxide is left over in the system. The mixture is denoted by the formula Fe_3O_4 and is called ferrosoferric oxide.

This reaction is reversible and is reversed if hydrogen gas is passed over heated ferric oxide in increased pressure.

Dmitry_Shevchenko [17]

The <u>Mole</u> is the SI unit that expresses the amount of substance.

Mole is defined as - The mole is the amount of substance containing the same number of entities as there are in the 12 grams of Carbon - 12.

Mole is denoted by using symbol mol.

      Mole = 6.022 x 10²³ elementary entities.

These number of elementary entities in 1 mole is equal to or called as an Avogadro's number.  Mole is equal to 6.022 x 10²³ because this number of entity is same as in exactly 12 g of carbon-12.

It is a very important SI unit of measured which is used by the chemists. Moles are used in measuring in small or tiny things such as atoms, molecules and the other tiny particles.

If a neutral compound is composed of carbon and hydrogen and you know that it has exactly 2 carbons connected by a double bond,
Oksanka [162]

Answer: 4 hydrogens

Explanation:

This is what the structure will look like C=C. Remember that it's important that all structures have a complete octet. As it looks right now each carbon is sharing 4 valence electrons so each needs 2 more bonds to hydrogen complete its octet.
