Characteristic properties can be used to describe and identify the substances, while non-characteristic properties, although can be used to describe the substances, cannot be used to identify them.
Temperature, mass, color, shape and volume are examples of non-characteristic properties.
Density, boiling point, melting point, chemical reactivity are examples of characteristic properties.
List of the properties observed by the scientist:
-----------------------------------------------------------------
Property Type of property
----------------------------------------------------------------
Volume: 5 ml non-characteristic
----------------------------------------------------------------
Color: blue non-characteristic
----------------------------------------------------------------
State: liquid characteristic
------------------------------------------------------------
density: 1.2 g/cm characteristic
------------------------------------------------------------
Reaction: reacts with CO2 characteristic

I'm pretty sure that significant figures is just the amount of numbers there is. So, in this case I think the answer would be D. 5
Answer is: c. It is incorrect because sodium phosphate is a compound that has a single composition.
Sodium phosphate is chemical compound composed of atoms connected with chemical bonds.
Pure substance is made of only one type of atom (element) or only one type of molecule (compound), it has definite and constant composition with distinct chemical properties.
Pure substances can be separated chemically, not physically, that is difference between pure substances and mixtures.
Answer:
What would be the value of g on the surface of the earth if its mass was twice and its radius half of what it is now ? g2=8g1 Thus , the value of g on the surface of the earth would be eight times the present value.
Explanation:
Hope this helps! :)
