57.1/16 atoms of oxygen combines with 42.9 / 12 atoms of carbon
3.56 atoms of oxygen combines with 3.575 atoms of carbon
one atom of oxygen combines with one atom of carbon
A appears to be CO ( carbon monoxide gas )
2 )
72.7 g of oxygen combines with 27.3 g of carbon
72.7 / 16 atoms of oxygen combines with 27.3 / 12 atoms of carbon

Answer:
9,500J
Explanation:
Distance= 50m
Force = 190N
Energy = Force x distance
= 190 x 50
= 9,500J
