question #12
you can separate the particles that make up sugar from the particles that make up sand because sugar are ____ and sand are not.
a malleable
b ductile
c soluble in water
d acidic
question #13
which formula listed below correctly finds density?
a d = m/v
b d = v/m
c d = g/v
d d = g/v
question #14
the state of matter is an example of a physical property.
true
false
select

Explanation:

• Question #12: Sugar is soluble in water while sand is not. This property allows their separation. Malleability and ductility are related to metals' ability to be shaped, and acidity is not relevant here for separation.
• Question #13: Density is defined as mass per unit volume, so the formula is $D = m/V$, where $m$ is mass and $V$ is volume.
• Question #14: The state of matter (solid, liquid, gas etc.) is a physical property as it can be observed without changing the substance's chemical identity.

Answer:

• Question #12: C. soluble in water
• Question #13: A. $D = m/V$
• Question #14: True
