if the sweetener was sugar how many moles of sweetener were in the gum

Answer & Explanation:

After 20 minutes the pieces of gum are weighed again. Concept: The molar mass (molecular weight) of sugar (sucrose) is large, 342.30 g/mol. Materials: A few pieces of Bazooka bubble gum (about 5)

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.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
