Consider the following equilibrium: 2SO2(g) + O2(g) 2SO3(g) Which of the following is a correct equilibrium expression?
Taya2010 [7]
The correct equilibrium expression would be one that has products over reactants, and to the power of their stoichiometric coefficient. Also, it would not include any liquids or solids.

The equilibrium expression for your balanced reaction is:

aev [14]

Answer:

6080 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of car = 800 Kg

Acceleration (a) of car = 7.6 m/s²

Force (F) =?

The force experienced by the car can be obtained as illustrated below:

Force (F) = mass (m) × acceleration (a)

F = m × a

F = 800 × 7.6

F = 6080 N

Thus, the experience a force of 6080 N
