In an endothermic reaction, the energy of the surroundings is
than the energy of
the system

THE CORRECT ONE IS THE SECOND ONE WITH THE SIGN IS " = "

Explanation:

THE GIVEN EXPLANATION : Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect. ... When a chemical bond is broken, it is usually accompanied by a release of energy.

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.
