Answer:
As you cool a matter to absolute zero, their kinetic energy reduces significantly and the molecules slows down and begins to aggregate together. ... As heat is added, the molecules gain more kinetic energy. This shown in their increase motion. When heat is withdrawn, the particles slows down hope this helped
The molar mass if carbon is 12g/mol
Answer:
0.2M NaOh
Explanation:
there are 0.2 mol of NaOH in 8.0 g. (8.0/40) =0.2. Molarity = mol/L = 0.2M.
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.
The Property of A Double Displacement Reaction is that the Element in front of a compound displaces the Other Metal in front of the other Compound. For eg.
BaCl2+Na2SO4=BaSO4+2NaCl
Here Barium, the metal in front of the compound BaCl2 displaces Na, the metal in front of the compound Na2SO4 to form BaSO4 and NaCl.
