How many grams of substance are formed when 112 grams of molten iron are axposed to water vapor​

Відповідь:To answer this question, we need to know the chemical reaction that occurs when molten iron is exposed to water vapor. Without this information, it's impossible to calculate the amount of substance that would be formed.

However, in general, the amount of substance formed in a chemical reaction depends on the stoichiometry of the reaction, which is determined by the balanced chemical equation. The molar ratios of the reactants and products in the equation can be used to convert between masses of the substances involved.

So, without more information, it's not possible to give a specific answer to this question.
