Which one of the following cIf we begin with 15.0 mL of a glucose solution with a concentration of 0.50 M and dilute it to a volume of 2.5 L, what is the concentration of the final, diluted solutionompounds is insoluble in water?

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the answers would be

the first one and the second one

the maximum mass of nh3 is nh3 in grams
