Answer : 42.3 ml of a 0.266 M 
solution are required.
Solution : Given,
Molarity of solution 1 = 0.266 M
Molarity of solution 2 = 0.075 M
Volume of solution 2 = 150 ml = 0.150 L (1 L = 1000 ml)
Formula used :
where,
= Molarity of solution 1
= Molarity of solution 2
= Volume of solution 1
= Volume of solution 2
Now put all the given values in above formula, we get
(1 L = 1000 ml)
Therefore, 42.3 ml of a 0.266 M solution are required.
Oxidation-Reduction Reactions. The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.
Hope I helped :)
Answer:
Explanation:
Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied being so far underground. Therefore, creating what we now know as Slate.
The pair of both compounds that have the same empirical formula are C6H12O6 and HC2H3O2. The answer is letter D. <span>H2O and H2O2, BaSO4 and BaSO3 and FeO and Fe2O3 do not have the same empirical formula.</span>
Given :
Volume of NaCl solution 2.5 L .
Molarity of NaCl solution is 0.070 M .
To Find :
How many moles are present in the solution.
Solution :
Let, n be the number of moles.
We know, molarity is given by :
So,
Therefore, number of moles of NaCl is 0.175 moles.
