Q AND ANS MOST POPULAR EXAM GUARANTEED SUCCESS
How does a mixture differ from a compound?
A mixture can be separated into its components by physical methods. A
compound can only be separated into its elements through chemical methods
Density is what kind of property?
intensive
properties that are independent of size
intensive properties
properties that are dependent of size
extensive properties
boiling point, color, temperature, luster, hardness
intensive properties
a mixture in which the composition varies from one region of the mixture to
another (salt & pepper)
heterogeneous mixture
a mixture made of multiple substances, but it appears to be one substance (salt
water)
homogenous mixture
a way to describe matter based upon observations and measurements
properties
