The acceleration of the car : 2.5 m/s²
<h3>Further explanation</h3>
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
<h3 />
Mass of the car = 1200 kg
Forward force = 3400 N
Friction force = 400 N
The direction of motion of the friction force will be opposite to the forward force, so that both of them can be subtracted to get the value of the net force (net force: combination / sum of all forces acting on an object)
So the acceleration :
The number of moles of carbon dioxide is 0.05 mol.
A molecule of CO2 contains one carbon atom and two oxygen atoms. One mole of CO2 contains one mole of carbon atoms and two moles of oxygen atoms. The mass of one atomic mole of an element equals the atomic mass in grams, and the molecular mass of an element or compound equals the sum of the atomic masses of each type of its constituent atoms.
Therefore, the mass of one mole of a molecule of an element or compound equals its molecular weight in grams. The number of grams in moles depends on the substance you have. To calculate it, find the atomic or molecular mass of the substance and multiply it by the number of moles.

I think your answer would be an Atom because it is referred to as the smallest unit of matter that retains the chemical properties of an element.
I Hope my answer help you :)
Answer:
see below
Explanation:
Swap cations and anions
K2NO3 is not balanced, it is either 2KNO3 or KNO3 and only 2KNO3 works in this case
FeCl2 (aq)+KNO3 (aq) → Fe(NO3)2 (aq) + 2KCL (aq)
