Awooden object has a mass of 10.782 g and occupies a volume of 13.72 ml. what is the density of the object determined to an appropriate number of significant figures?

7.859 × 10^-1 g/mL

Explanation:

D=mass/volume

10.782g/13,72ml= 0.78586 g/ml

7.859 x 10^-1 g/ml

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 don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
