The correct answer is this one: "The amount of energy before and after the explosion depends on the type of reaction." The energy involved in an explosion is that t<span>he amount of energy before and after the explosion depends on the type of reaction, how strong and how weak; how destructive or less destructive.</span>

Explanation:
Answer:
B. 6m/s southeast
Explanation:
velocity= distance / time
= 180/ 30
6m/s southeast
A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 15 carbon atoms, will have 32 hydrogen atoms.
GPE = mgh
Where GPE is gravitational potential energy (J), m is the mass ob the object (kg), g is acceleration due to gravity (m/s²) and h is the height (m)
m = 4 kg
g = 9.8 m/s²
h = 3 m
By substitution,
GPE = 4 kg x 9.8 m/s² x 3 m
= 117.6 J
≈ 118 J
Hence, the answer is D
