Answer:
<h3>The answer is 0.91 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual volume = 198.2 mL
error = 200 - 198.2 = 1.8
So we have

We have the final answer as
<h3>0.91 %</h3>

Answer:
Phase C - Liquid State
Phase E - Gaseous State 
Explanation:
Usually, in phases of water, we have the following;
When temperature is less than zero, it is said to be in its solid phase as ice.
When temperature is between 0 to 100, we can say it is in the liquid phase as water. 
When temperature is above 100°C, It is said to be in the gaseous phase as vapour. 
From the diagram;
Phase C is the only liquid state because it falls between temperature of 0°C and 100° 
Also, only phase E is in the gaseous phase because the temperature is above 100°C.
 
        
             
        
        
        
Potassium oxide has the antifluorite structure. The antifluorite structure have compounds with the stoichiometry X₂Y, where X is the cation and Y is the anion. In the antifluorite structure <span>positions of the </span>cations<span> and </span>anions<span> are reversed relative to their positions in calcium fluoride.</span>
Potassium ions coordinated to 4 oxide ions, <span>potassium ions are all in the tetrahedral holes.</span>
        
             
        
        
        
The states in which water occur in are ice liquid and gas
