Which of the following is a molecular compound held together by covalent bonds?
(A) CaO (C) FeO
(B) SO3 (D) Li2O

the answer is alpha particles hope i you

the answer is definitely c.

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

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.
