<h3><u>Answer;</u></h3>

Decomposition of calcium carbonate

CaCO3(s) → CaO(s) + CO2(g)

<h3><u>Explanation;</u></h3>
  • <em><u>Decomposition reactions are types of reaction that occurs when a reactant is broken down into two or more products. </u></em>
  • Decomposition may either be thermal where heat is used to break a reactant or may be catalytic where a catalyst is used to break down a reactant to yield two or more substance, for example decomposition of hydrogen peroxide.
  • <em><u>All metal carbonates decompose to produce a metal oxide and carbon dioxide gas.</u></em>
  • <em><u>Calcium carbonate undergoes thermal decomposition to form calcium oxide and carbon dioxide. </u></em>
  • The equation will be;

CaCO3(s) → CaO(s) + CO2(g)

The equation is balanced as the number of atoms of each element are equal on both side.

Ice fishermen sit on top of frozen lakes in the winter and catch fish in the liquid water below through holes cut in the ice she
melomori [17]

Answer:

This is because below 4°c, water unlike other materials becomes less dense when it's temperature is further lowered.

Explanation:

Due to the unusual nature of water; at about 4°c, the behavior of the density of water in relation to its temperature reverses. This means that water becomes less dense as it becomes colder below 4°c. The colder parts therefore floats to the top of the water body while the warmer part sinks allowing the top to freeze and the remaining body below to remain in its liquid state.

The freezing of the top of the lake alone protects the remaining depth of water from freezing by acting as an insulator and preventing further heat loss from the water to the ambient space. If this had not been the case, and water froze all through, marine lives will freeze to death and it will be more difficult to melt the ice come the next summer.

This behavior is due to the hydrogen bonding of the water molecules.
