Answer:
The density of solution is 1.283 g/mL.
Explanation:
Molarity of the KOH before dilution = 
Volume of the solution before dilution = 
Molarity of the KOH after dilution = 
Volume of the solution after dilution = 
(1 mL = 0.001 L)
Mass of 0.2076 moles of KOH:
0.2076 mol × 56 g/mol = 11.6256 g
Mass of KOH is solution = 11.6265 g
Mass of the solution = M
Mass percentage of solution = 30.0% of KOH
M = 38.755 g
Density of the solution , d= 
The density of solution is 1.283 g/mL.
To find out the number of water molecules produced simply use Avogadro’s constant, where 1 mol of any compound is equal to 6.02 x 10^23 molecules of the substance.
Multiply 0.815 to this value.
Answer:
See the explanation below, please.
Explanation:
In redox reactions (oxide reduction) the transfer of electrons between compounds occurs.
In oxidation, electrons are lost (positive charge increases). Example:
Mg ---> Mg2 + + 2 e- (passes from Mg ° to Mg 2+)
On the other hand in the reduction, electrons are gained (negative charge increases or the positive one increases). Example:
Cl2 + 2e- ---> 2 Cl- + 2 e- (passes from Cl ° to Cl-)
Inorganic chemistry studies the chemical compounds in inorganic, or non-living things such as minerals and metals.
