The dissociation of sulfurous acid (h2so3) in aqueous solution occurs as follows:
h2so3 > h+ + hso3-
hso3- > h+ + so32-
if .50 moles of sulfurous acid are dissolved to form a 1 l solution, which of the following concentrations will be least at equilibrium?
the answer is by adding the vectors.

the river current is moving with velocity vc=10 km/h in a certain direction relative to the shore. the boat is moving with velocity vb=10 km/h relative to the current, and in the same direction as the current, so the total velocity of the boat relative to the shore will be equal to the sum of the two vectors (because they are in the same direction):
v=vb+vc = 10 km/h + 10 km/h = 20 km/h
petroleum refining or oil refining is a manufacturing method in which crude oil is removed from the ground, molded and purified into valuable products like liquefied petroleum gas (lpg), kerosene, asphalt base, jet fuel, gasoline, heating oil, fuel oils etc. crude oil contains hydrocarbon molecules. refining petroleum refining relates to the method of transforming crude oil into useful products. crude oil is made of hundreds of various hydrocarbon molecules, which are distributed by the method of refining.
answer: e. the negative side of each water molecule is attracted to the positive sides of nearby molecules.
explanation: the high melting point, boiling point, and surface tension of water is due to the strong inter molecular forces of attraction present between the water molecules.
the molecules are bonded through hydrogen bonding which arises due to polarity which is developed due to electronegativity difference between hydrogen and oxygen atoms.
oxygen being more electronegative develops negative charge and hydrogen acquires positive charge, which leads to special kind of dipole dipole forces called as hydrogen bonds.
