A. solar energy
the earth is warmed by the sun, which is solar (or infrared).
Mass of carbon monoxide : 0.95 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂
MW Fe₂O₃ : 159,69 g/mol
mol Fe₂O₃ :

mol ratio Fe₂O₃ : CO = 1 : 3, so mol CO :

mass CO (MW = 28,01 g/mol) :

I think the effect of increasing temperature would be; the equilbrium will shift back wards. Increase in temperature favors backward reaction since the forward reaction is exothermic and the backward reaction is endothermic. Therefore, the equilibrium will shift back wards, and there will be more reactants (H2 and Cl2) compared to the products
