<h3>What is an Empire?</h3>
A political unit known as an empire is made up of many different nations and regions that is "often established by conquest and divided into a dominant center and submissive peripheries." By a strict definition, an empire is a sovereign state with an emperor as its head of state; however, not all states with a combined territory under the control of supreme authorities are referred to as empires or ruled by emperors, and not all self-described empires have been recognized as such by historians and contemporaries (the Central African Empire, and some Anglo-Saxon kingdoms in early England being examples).
There have been "brutal and comparatively peaceful, centralized and decentralized, ancient and modern" Empires.

<h3><u>Answer;</u></h3>
At room temperature, the solubility of which solute in water would be most affected by a change in pressure?
<h3><u>Explanation;</u></h3>
- As the pressure on a gas confined above a liquid increases, the solubility of the gas increases in the liquid.
- Carbon dioxide gas is most soluble in water under conditions of high pressure and low temperature.
- The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water is used will be less compared to warm water.
<h3>
Answer:</h3>
81.9 grams
<h3>
Explanation:</h3>
From the question we are given;
- Half-life of C-14 is 5730 years
- Original mass of C-14 (N₀) = 150 grams
- Time taken, t = 5000 years
We are required to determine the mass left after 5000 years
- N = No(1/2)^t/T, where N is the remaining mass, N₀ is the original mass, t is the time taken and T is the half-life.
t/T = 5000 yrs ÷ 5730 yrs
= 0.873
N = 150 g ÷ 0.5^0.873
= 150 g × 0.546
= 81.9 g
Therefore, the mass of C-14 left after 5000 yrs is 81.9 g
