Answer: Option (b) is the correct answer.
Explanation:
A compound is defined as the substance in which different atoms chemically combine together in a fixed ratio by mass.
For example, is a compound as here both calcium ion and nitrate ion chemically combine together.
A compound can be broken down into its constituent particles.
Whereas an atom is the smallest particle present in a substance. It is indivisible in nature.
A molecule is a substance that contains either same or different atoms which are chemically combined together.

Answer:
B. The student chose the correct tile, but needs to flip the tile to make the units cancel
Explanation:
Based on the reaction:
2AgNO₃(aq) + Cu(s) → 2Ag(s) + Cu(NO₃)₂ (aq)
<em>2 moles of AgNO₃ react per mole of Cu producing 2 moles of Ag and 1 mole of Cu(NO₃)₂</em>
Thus, if you want to produce 6.75moles of Cu(NO₃)₂ you need:
= 13.50 moles of AgNO₃ are needed
Thus, if you analize the tile shown by the student:
