In the chemical reaction: naoh (s) + h2o → na+ (aq) + oh- (aq), which substance (or substances) is in solution? oa) nat (aq) only ob) oh" (aq) only oc) nat (aq) and oh (aq) od) naoh (s)

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

elements make up everything, and they combine to make compounds.

the answer is c

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.
