Plants A and B have the same mass, but planet A is half the size of planet B. Which statement correctly explains the weight you would experience on each
planet?
A. You would weigh less on planet A because the distance between
you and the planet's center of gravity would be smaller.
B. You would weigh more on planet A because the distance between
you and the planet's center of gravity would be smaller.
C. You would weigh the same on both planets because the masses
of the planets are the same.
D. You would weigh the same on both planets because your mass
would be the same on both.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the answer is c i believe

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
