Question

the more density an object has, the more likely it is to______ in water
○ melt
○ sink
○ freeze
○ float
question 7
in a chemical equation they are found after the arrow:
○ reactants
○ products
○ reagents

Explanation:

1. For the first question: An object sinks in water if its density is greater than water's density ($1\ \text{g/cm}^3$); higher density makes sinking more likely. Melt/freeze relate to temperature, float needs lower density.
2. For Question 7: Chemical equations follow the format $\text{Reactants}

ightarrow \text{Products}$. The arrow points to the substances formed, which are products. Reactants/reagents are before the arrow.

Answer:

1. Sink
2. Products
