Given the equations below, what is the heat of reaction for the process in which carbon monoxide is formed from its elements? C(s, graphite) + O2(g) → CO2(g), ∆H = –393.5 kJ

CO2(g) → CO(g) + ½O2(g), ∆H = 283.0 kJ

A) –676.5 kJ
B) 110.5 kJ
C) 676.5 kJ
D) –110.5 kJ

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific

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.
