answer: the freezing point of water will decrease by 7.44 k.
moles of sugar = 4 moles
mass of water = 1 kg
i = van't hoff factor of sugar = 1
the freezing point of water will decrease by 7.44 k.
i think its theory but im not to sure
we are given a mixture of hydrochloric acid (hcl) and acetic acid . the given mixture is a mixture of strong acid and a weak acid.
strong acid is defined as the acid that can be get completely ionized or dissociated in an aqueous solution. weak acid is defined as the acid which does not dissociate completely in an aqueous solution.
when a mixture of hcl and is titrated against naoh (strong base), strong acid will get neutralized first because it is completely dissociated in the solution and can be easily neutralized.
option a - atoms gain, lose, or share electrons to achieve a full valence shell.
the octet rule is best explained as atoms gain, lose, or share electrons to achieve a full valence shell complete or to attain electronic configuration of noble gases. the main objective to do this is to attain stability. the octet rule is a rule that shows the view that atoms of elements serve to join like that each atom has eight electrons in its valence shell, providing it the same electron configuration as a noble gas.
