Continue to use the solubility curve graph to determine if the following solutions are saturated or unsaturated. If they are unsaturated determine how much more solute
should be added to make a saturated solution.
7. (10 Points) A solution that contains 70g of NaNO3 at 30°C (in 100 mL H2O)
8. (10 Points) A solution that contains 50g of NH, Cl at 50°C (in 100 mL H,0)
9. (10 Points) A solution that contains 70g of KI at 0°C (in 100 mL H,0)
10. (10 Points) A solution that contains 20g of KCloz at 50°C (in 100 mL H2O)

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
