Consider the following intermediate chemical equations. What is the enthalpy of the overall chemical reaction?

-999 kJ
-250 kJ
250 kJ
999 kJ

your answer would be “dry”

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.
