Answer:
Kinetic energy is directly proportional to mass
Explanation:
Kinetic energy is directly proportional to the mass of an object and also directly proportional to the square of the velocity of that object:
Notice that if we keep velocity constant and only increase the mass of a object, the kinetic energy of that object would increase, as we've already emphasized the direct relationship between the kinetic energy term and the mass term.
Let's take a simple example: assume that object 1 and object 2 are both moving at the same velocity but object 1 has a much lower mass than object 2. According to the equation, object 1 has lower kinetic energy. This object can then transform all of its kinetic energy into some other form, say, heat the ground. The heat transferred will be significantly lower than by the object 2 moving at the same velocity but having a much greater mass.

Answer:
2C₈H₁₈(g) + 25O₂(g)→16CO₂(g) + 18H₂O
Explanation:
To balance an equation, the moles of one element on one side of the equation should be the same as those on the other side of the equation. This is because (as a law of thermodynamics), in a chemical reaction, the matter is not destroyed nor created - atoms are only rearranged.
Carbon monoxide is produced in an engine
when incomplete combustion happened. In a combustion engine intake valve, it
combines the fuel and air (nitrogen and oxygen) and when spark plug ignites it
pushes the piston downwards. After that piston will push itself upward and
pushes the air that was generated by the combination of those components in the
exhaust valve. This is a repeated cycle which keeps the engine running. In a
perfect combustion process the air being released are carbon dioxide, water and
nitrogen. But when an incorrect ratio of the combination of fuel and air in the
engine is processed, carbon monoxide is being generated.
