Every action has an equal but opposite reaction.
So, if I push on a door with a force of 5 N, the door will push back on me with a force of 5 N.
Newton's third law states that all forces occur in pairs such that if one object exerts a force on another object, then the second object exerts an equal and opposite force on the first.
Summed up, this means that "For every reaction, there is an equal and opposite reaction."
I hope this helped!
Answer:
False
Explanation:
It is not a chemical change, it is a physical change because the molecules of the bread didn't change, the form of the bread did
1.5 mol H20
2.5 mol H20
O 3.5 mol NO2
O 1.0 mol NO2
Answer:
3.5 moles of NO2.
Explanation:
The balanced equation for the reaction is given below:
3NO2 + H2O —> NO + 2HNO3
Next, we shall determine the excess reactant. This is illustrated below:
From the balanced equation above,
3 moles of NO2 reacted with 1 moles H2O.
Therefore, 6.5 moles of NO2 will react with = (6.5 x 1)/3 = 2.17 moles of H2O.
From the above calculations, we can see that it will take a higher amount i.e 2.17 moles than what was given i.e 1 mole of H2O to react completely with 6.5 moles of NO2.
Therefore, NO2 is the excess reactant and H2O is the limiting reactant.
Next, we shall determine the number of mole of the excess reactant that reacted in the reaction. This is illustrated below:
From the balanced equation above, we can see that 3 moles of NO2 reacted with 1 mole of H2O.
Finally, we shall determine the leftover mole of the excess reactant after the reaction. This is illustrated below:
Given mole of NO2 = 6.5 moles
Reacted mole of NO2 = 3 moles
Leftover mole of NO2 =...?
Leftover mole = Given mole – Reacted mole
Leftover mole of NO2 = 6.5 – 3
Leftover mole of NO2 = 3.5 moles.
Therefore, 3.5 moles of NO2 remained after the reaction.
