15.630 g milk chocolate bar ks found to contain 9.815g of sugar. how many milligrams of sugar does the bar contain?
2 answers:
<u>Answer:</u> The mass of sugar that the bar contains is 9815 milligrams.
<u>Explanation:</u>
We are given:
Mass of milk chocolate bar = 15.630 g
Mass of sugar in it = 9.815 g
Converting the mass from grams to milligrams, we use the conversion factor:
1 g = 1000 mg
So,
Hence, the mass of sugar that the bar contains is 9815 milligrams.

Answer: Energy of reactants = 30, Energy of products = 10
Exothermic
Activation energy for forward reaction is 10.
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Energy of reactants = 30
Energy of products = 10
Thus as energy of the product < energy of the reactant, the reaction is exothermic.
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
for forward reaction is (40-30) = 10.
