They both ask for an amount of something
Answer:
No mass of HCl could be left over by the chemical reaction because is the limting reactant and it is all consumed.
Explanation:
Our reactants are: HCl and NaOH
Products are: NaCl and H₂O
This is a neutralization reaction that can also be called an acid base reaction, an acid and a base react to produce water and a neutral salt, in this case where we have strong acid and base.
Ratio is 1:1. We convert mass to moles:
35 g . 1 mol / 36.45 g = 0.960 moles of HCl
73 g . 1 mol / 40 g = 1.82 moles of NaOH
As ratio is 1:1, for 0.960 moles of HCl we need 0.960 moles of NaOH and for 1.82 moles of NaOH, we need 1.82 moles of acid.
As we only have 0.960 moles of HCl and we need 1.82 moles, no acid remains after the reaction goes complete. HCl is the limiting reactant, so the acid, it is all consumed.
Answer:
T^2 α r^3
Explanation:
The relationship between the period of revolution of planets and their mean distances from the sun is given by Kepler's third law.
Kepler's laws of planetary motion describe the orbits of objects around the sun.
This third law states that; "the square of the period of revolution of planets are proportional to the cubes of their mean distances from the sun. Hence; T^2 α r^3.
Where;
T = period of revolution of the planets
r = mean distance of the planet from the sun
