Answer from: saucyboyFredo

From the equation of the reaction, the mass of Fe produced from 14 moles of H₂ is 588 g.

What grams of iron are produced from 14 moles of H₂?

The equation of the reaction is given as follows:

Fe3O4 + 4 H2 → 3 Fe + 4 H2O

From the equation of the reaction, 4 moles of H₂ produces 3 moles of Fe.

14 moles of H₂ will produce 14 * 3/4 moles of Fe = 10.5 moles of Fe.

Molar mass of Fe = 56 g

Mass of 10.5 moles of Fe = 56 * 10.5

Mass of 10.5 moles of Fe = 588 g

Therefore, the mass of Fe produced from 14 moles of H₂ is 588 g.

Answer from: NeverEndingCycle

$\boxed{\text{586 g}}$

Explanation:

We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

M_r: 55.85

Fe₃O₄ + 4H₂ → 3Fe + 4H₂O

n/mol: 14

1. Use the molar ratio of Fe:H₂ to calculate the moles of Fe.

$\text{Moles of Fe = 14 mol H$_{2}$} \times \dfrac{\text{3 mol Fe}}{\text{4 mol H$_{2}$}} =\text{10.5 mol Fe}$

2. Use the molar mass of Fe to calculate the mass of Fe

$\text{Mass of Fe = 10.5 mol Fe} \times \dfrac{\text{55.85 g Fe}}{\text{1 mol Fe}} = \textbf{586 g Fe}\\\\\text{The reaction will produce $\boxed{\textbf{586 g}}$ of Fe}$

Answer from: Quest

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
