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.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

they are both synthetic elements

explanation:
