Acar experiences a 300 n force to the right from the engine and separate 150 n force due to friction and air resistance to the left.(a) will accelerate to the left (b) will accelerate to the right (c) will not accelerate

(B) Will accelerate to the right.

Explanation:

The force applied to the car is equal to:

F1 = 300N, this force is applied to the right

Opposed to this force, the resistance force of the air is counterclockwise, and is equal to:

F2 = 150N, this force is to the left

The total force to be applied to the car will be equal to:

Ftotal = F1 + F2

Replacing values, we have:

Ftotal = 300N - 150N = 150N

The total force applied to the car will be equal to 150 N, and this force is directed to the right. Consequently, the car will accelerate in that same direction due to the same force (right).

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
