Answer:
0.6 Molar
Explanation:
According to the Question,
In 500 mL of water ,
0.2 mol sample of MgCl is present and 0.1 mol of KCl is present.
Thus ,
Concentration of Cl anion in the solution will be the sum of Cl anion concentration from MgCl and KCl.
From MgCl , 0.2 mol of Cl anion will come and 0.1 mol of KCl anion will come ,
Thus , 0.3 mol of Cl anion will come totally .
So, Cl anion concentration will be = 0.6 M
Answer: Thus the value of the equilibrium constant is
Explanation:
Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.
At eqm. conc. (0.20) M (0.25) M (1.20) M
The expression for equilibrium constant for this reaction will be,
The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Thus the value of the equilibrium constant is
Explanation:
oxidation is adding of oxygen and removal of hydrogen.
Reduction means removal of oxygen and addition of hydrogenm
What you would want to do here is dividing mass by density. In fact, density is referred to as a ratio of mass to volume. There is no need for any unit conversion as they are already comparable. So the result should be 105g / 11.3g/ml =9.3ml.
English is not my first language, so sorry for language issues of any kind.
It has bent geometry, which is similar to H2O, with the same angle of 109.5 degrees between 2 single H-S bonds.
