Select all of the following that would act to make the value of k become larger. A. The temperature of the reaction is decreased.
B. The reactant has many sites for a successful collision to occur.
C. A catalyst is used which acts to lower the activation energy for the reaction.
D. The mobility of the molecules is decreased so that there are fewer collisions.
E. The reaction is heated.
F. The concentration of the reactant is increased.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
