Decide the mechanism by which the following alkyl halides will be converted to alcohols by the substitution of the nucleophile, oh-.
r-x + oh- > r-oh + x-
3-bromo-2-methylpentane
1-chloro-2,2-dimethylpropane
1-bromo-1-methylcyclohexane
1-bromo-2-methylcyclohexane

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.

i hoped this , can i get brainliest plzgod bless you

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
