<span>Made up of particles packed relatively close together, having an indefinite shape but a definite volume</span>
Answer:
<h2>
<u>Suspension.</u></h2>
Explanation:
Since the particles of a suspension are larger than those of solutions and are insoluble, they settle to the bottom of the container over time. Therefore, suspensions need to be shaken to ensure that the solute particles are evenly distributed throughout the mixture.
Answer:
The motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.

Answer is: <span>the acidity of water reduce the mass of seashells.

Balanced chemical reaction:
CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + CO₂(g) + H₂O(l).
Calcium carbonate (CaCO₃) dissolves in hydrochloric acid and gas carbon(IV) oxide is formed.
Calcium carbonate is inorganic salt insoluble in water, but soluble in acidic solutions.
