Answer:
0.85M
Explanation:
Given parameters:
Mass of CuCl₂ = 400g
Volume of water = 3.5L
Unknown:
Molarity of the solution = ?
Solution:
Molarity is one of the ways of expressing the concentrations of a solution. It is defined as the number of moles per unit volume of a solvent.
Molarity =
To find the number of moles of CuCl₂;
Number of moles =
Molar mass of CuCl₂ = 63.6 + 2(35.5) = 134.6g/mol
Number of moles = = 2.97moles
Molarity = = 0.85M
Here is the answer. Although its chief uses are in the preparation of sulfuric acid, sulfur trioxide, and sulfites, sulfur dioxide also is used as a disinfectant, a refrigerant, a reducing agent, a bleach, and a food preservative, especially in dried fruits.

Since SeO2 dissolves in water to produce selenium acid, it is regarded as an acidic oxide.
The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. 350 °C (662 °F; 623 K). The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. It serves as a catalyst, reagent, oxidizing agent, and antioxidant in lubricating oils. OSHA regulates selenium oxide; thus, it is listed on the Hazardous Substances List. It can be produced chemically by dehydrating selenous acid or chemically by burning selenium in oxygen, nitrogen dioxide, or hydrogen peroxide.
