A student has a canister full of 45 marbles. There are two types of marbles in the canister. Some of them have a mass of 4.50 g (type A) and the other type has a mass of 3.27 g (type B). The mass of the marbles, including the canister is 201.27 g. The mass of the canister is 14.76 g. Calculate the number of A and B marbles in the canister.

i believe it is a.) released into

explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

a electronegativity decreases beacuse the size of nucleus is bigger.

it is b that is the answer.
