Question

you notice that the drain in your kitchen sink is clogged, although you did not throw any solids down the drain. you predict it has become clogged because substances dissolved in the water reacted to form a solid, which is called a precipitate. you begin a study in which you will mix various liquid solutions to determine whether a solid will form. based on the results, you determine that it is possible for the substances dissolved in liquid solutions to react to form a solid.
which of the following is the hypothesis of this scenario?
o you mix various liquids to determine whether a solid will form.
o you predict that your sink became clogged because substances dissolved in the water reacted to form a solid.
o you determine that the substances dissolved in liquid solutions can react to form a solid.
o you notice that the drain in your sink is clogged.

Explanation:

A hypothesis is a proposed explanation for a phenomenon. In this scenario, the proposed explanation for the sink - clogging is that substances dissolved in water reacted to form a solid. The other statements are either observations (like noticing the drain is clogged), actions (mixing liquids), or conclusions (determining substances can react to form a solid).

Answer:

You predict that your sink became clogged because substances dissolved in the water reacted to form a solid.
