Question

balance the following chemical equation and state whether they are exothermic or endothermic
1)Na+H2o=NaOH+H2
2)FeSO4=FeO3+SO2+SO3​

Answer 1

HERE'S YOUR ANSWER ________________________The balanced equations for the above reactions are

:1) 2Na+ 2 H2O = 2 NaOH + H2The reaction is highly Exothermic as Hydrogen is evolved as a by-product.= = = = = = = = = =

2) 2 FeSO4 = Fe2O3 + SO2 + SO3The reaction is Endothermic as the reaction is carried out by providing heat to the reactant.________________________HOPE HELPED! ! HAPPY TO HELP :)
