Answer:
h20 is water ash a chemical compound
Explanation:
The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.
<h3>What is conversion factor?</h3>
Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.
Given that quantity of salt solution = 2.50 L
We know that, 1 L = 1.06 qt
Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:
2.50L = 2.50L × 1.06qt/L = 2.65qt
Hence required value is 2.65qt.

Answer:
Empirical formula = S₁Cl₂ = SCl₂
Explanation:
The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.
This compound contains 31.1% sulfur and 68.9% chlorine.
That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.
Convert the mass of each element to moles using the molar mass from the periodic table.
Moles of Sulfur = 
= 0.9699
Moles of Chlorine= 
= 1.9434
Divide each mole value by the smallest number of moles calculated.
Units of sulfur = 
= 1
Units of Chlorine = 
= 2
Empirical formula = S₁Cl₂ = SCl₂
(35/18.02)(6.02kJ)=11.6926 kiloJoules
