Answer:
The three methods we can use to separate a mixture are:
1.sublimation
example: sand and camphor
2.centrifugation
example:cream from milk
3.evaporation
example:salt from sea water
Sugar dissolves and is spread throughout the glass of water<span>. The </span>sand<span> sinks to the bottom. The sugar-</span>water<span> is a homogeneous mixture while the </span>sand-water<span> is a heterogeneous mixture. Both are mixtures, but only the sugar-</span>water<span> can also be called a </span>solution. i got this from :<span>www.chem4kids.com/files/matter_solution.html

Answer:
A
Explanation:
a vector quantity must have a direction. without a direction the value is called a scalar quantity
ie: velocity is a vector because it is how fast an object moves in a certain direction. speed is a scalar because it is how fast an object moves regardless of direction
PH 1 - 6 = Acids
pH 7 = Neutral
pH 8 - 14 = Bases
An alkaline is a base that is very soluble in water.
Since we know the solution has a ph of 14, it cannot be A, since A is an acid. It can however be B or C. I'd say that the most logical answer would be B, because no testing has been done for other alkaline properties.
Answer:
3203.2 g
Explanation:
Since, Density=Mass/Volume
So,Mass =Density * Volume
= 176 * 18.2
= 3203.2 g
