Answer:
11
Explanation:
Moles of KOH =
Volume of water = 10 liters
Concentration of KOH is given by
is strong base so we have the following relation
So, pH of the solution is 11
Let x be the oxidation state of S.
Therefore,
2x + 3(-2) = -2
2x = -2 + 6
2x = 4
x =2.
Hence oxidation state of S is +2.
Hope this helps!
Answer:
K < Mg < P < O
Explanation:
The trend for electronegativity is that it increases as you go up and to the right of the periodic table. If we look at the periodic table, O is more to the right and up of P and the other elements. Then we see that P is more up and right to the other elements. Then we see that Mg is more up and to the right of K. So we get the order of K < Mg < P < O. Hope this helps!
The potential energy of the ball was converted to elastic energy. You can think of it as the mass of the ball being mounted to a spring that compresses when you hit the floor - but there will be some friction (both inside the ball, and particularly between the ball and the floor) which will dissipate energy:
it should be hittin the floor
The presence of unsaturation that is carbon-carbon double or triple bonds can be tested qualitatively by bromine test. In this test, the unknown sample is treated with a small amount of elemental bromine in organic solvent (which is deep brown in color). The disappearance of deep brown color of bromine results due to reaction of bromine with unsaturated sample.
The reaction of eugenol with bromine is given as:
Since the number of atoms of each element in the reactant side is equal to the number of atoms of elements of product side. Thus, the reaction is balanced.
The reaction between eugenol and bromine is shown in the image.
