Answer:

d.  Atoms are rearranged.

Explanation:

In a chemical reaction, what happens is that atoms are simply rearranged when the process takes place.

According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but atoms are simply rearranged".

Therefore:

  1. Atoms are not created
  2. Atoms are not destroyed
  3. Atoms are simply rearranged.

1. What could be the energy of a flying aeroplane?<br><br> 2. Is work the same as power?
Doss [256]

Explanation:

The total energy of an aircraft flying in the atmosphere can be calculated using equation 1. [2]

E = ½ m v2 + mgh

A Boeing 737-300 has a maximum takeoff weight of 5.65 × 104 kg, a cruise altitude of h = 10,195 m, and cruise speed of 221 m/sec. Inserting these numbers into the above equation, we obtain 7.03 GJ for the energy at cruise conditions. [3] However, the engines mounted onto the wings of the plane are required to provide additional energy per time, power, in order to keep the aircraft flying at a constant altitude and speed

Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.
