What statement best describes solution

Solution is a mixture of solvent and solute. Which dissove completely.

Examples of Solvent - Water

                     Solute - Salt

                     Solution - Salt solution

Together when the combines, it became a solution

*** It have to dissolve completely. Particles cannot be left in the cup(container). The only way to seprate them is to use EVAPORATION METHOD.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
