Answer:
- <em>You can determine through observation that a mixture is a suspension </em><u>from the fact that particles separate and a solid substance is formed at the bottom of the mixture.</u>
Explanation:
<em>Suspensions</em> are heterogenous mixtures where particles settle when times passes.
The partilces in suspensions are not dissolved (solvated by a solvent). The mixtures where the particles are dissolved are solutions. Then, solutions and supensions are different in that the former have the particles solvated and the latter not.
The particles in a solution are molecules or ions. Such solvated particles in a solution are very small; in comparison,the particles on a suspension are larger. Then, the weight of the particles in a suspension makes that they separate from the liquid and settle down.
They did not repeat their tests multiple times.
Reason being is using the same stopwatch doesn’t matter and changing the reactants won’t help, and you without a doubt need more than one person collecting the data so,
They did not repeat their tests multiple times is the answer.
