What is the product of 3fe + 4h20 > fe3o4+4h2
1 answer:
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 and is called ferrosoferric oxide.
This reaction is reversible and is reversed if hydrogen gas is passed over heated ferric oxide in increased pressure.

Answer: a substance that increases the hydroxide ion concentration of a solution
Explanation: According to Arrhenius concept, an acid is a substance which donates hydronium ions ions when dissolved in water and base is a substance which donates hydroxide ions
ions in water.
According to the Bronsted Lowry conjugate acid-base pair, an acid is a substance that donates protons and a base is a substance that accepts protons.
According to Lewis concept, an acid is the substance which accepts electron pairs and abase is a substance which donates electron pairs.
Thus a substance that increases the hydroxide ion concentration of a solution is an Arrhenius base.
