The percentage yield of the reaction : 93.3%
Mass of FeCO₃ 2310.44 g
<h3>Further explanation
</h3>
The reaction equation is the chemical formula of reagents and product substances
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
4 FeCO₃ + O₂ ⇒ 2 Fe₂O₃ + 4CO₂
MW FeCO₃ : 115,854 g/mol
MW Fe₂O₃ : 159,69 g/mol
mol of 1 kg Fe₂O₃ = 1000 g
mol of FeCO₃
mass of FeCO₃
a purity of 62.8%
Answer: If you mean N2 and not Nz, it should be C.
Explanation:
I think the correct answer would be the first option. A chemical reaction that has an increase in entropy and a decrease in enthalpy is spontaneous at high temperatures. This reaction absorbs heat for it to occur so supplying heat to it is important.
PH becomes lower when the H+ ion concentration increases.
<span>pH becomes higher when the H+ ion concentration decreases. </span>
<span>pH becomes lower when the OH- ion concentration decreases. </span>
pH becomes higher when the OH- ion concentration increases.
Hope this helps!
