Sodium will react with oxygen to form sodium oxide. use the formula below to determine how many grams of sodium oxide will be formed if 46 grams of sodium are used in the reaction.

not clear

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
