Answer:
Explanation:
The three of them increase from left to right across the periods of the periodic table, and at the same time, they decrease from up to down across the groups of the periodic table.
Ionization Energy is defined as the energy required to remove the atom of an electron.
Electron affinity is defined as the change in energy when electron is added to a negative ion.
Electronegativity is the ability of an atom to attract other atoms to itself.
The Indicator changes color in a titration is Indicator Point

[O2]: There is no change.
[SO3]: There is no change
Explanation:
For an exothermic reaction, increase in temperature decreases the concentration of products and increases the concentration of reactants since increase in temperature shifts the equilibrium position to the left hand side.
Increase in pressure and decrease in volume will shift the equilibrium position towards the right hand side which means more SO3 in the system.
Catalyst increases the rate of forward and reverse reaction simultaneously hence at equilibrium, the concentration of reactants and products remain unchanged.
Answer:
proton and electrons orbit close together around a center nucleus
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 :
