A 1.4 g sample of sodium acetate is dissolved in about 50 mL of water. Concentrated HCl is added to adjust the pH 4.50, and the solution is diluted to a final volume of 100.0 mL. What is the molarity of CH3CO2H in this solution?

100.0 mL-4.50 50 mL ha hakdog multiplie it bb

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

i think that the answer is c
