Answer:
- We are commonly asked to find the extra reactants in a chemical equation. We can find it after balancing the equation and seeing the amount of moles that are present for each substance.
- Hence in chemistry and thermodynamic reactions it is the extra reactants that are not used up during the combustion process and therefore is excess of a said element.
- There are also limiting reagent which is the substance that limits the amount that can react and can be produced in a chemical reaction

Answer:
G) AC = 12
Step-by-step explanation:
5/10 = (x + 5)/(3x + 3)
15x + 15 = 10x + 50
5x = 35
x = 7
AC = 7 + 5 = 12
Answer:
The resultant velocity of the airplane is 213.41 m/s.
Step-by-step explanation:
Given that,
Velocity of an airplane in east direction, 
Velocity of wind from the north, 
Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.
We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :


v = 213.41 m/s
So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.
