Answer:
This is an example of chemical change because the Kool aid dissolved and turned the water red
A mole of an element refers to 6.02e23 atoms so they would have the same amount of atoms
N₂ : limiting reactant
H₂ : excess reactant
<h3>Further e
xplanation</h3>
Given
mass of N₂ = 100 g
mass of H₂ = 100 g
Required
Limiting reactant
Excess reactant
Solution
Reaction
<em>N₂+3H₂⇒2NH₃</em>
mol N₂(MW=28 g/mol) :

mol H₂(MW= 2 g/mol) :

A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactans become a limiting reactants
From the equation, mol ratio N₂ : H₂ = 1 : 3, so :

N₂ becomes a limiting reactant (smaller ratio) and H₂ is the excess reactant
the answer is C.
The PH will initially remain close to 4.76 then decrease quickly when the buffer capacity is exceeded
Mass/volume cause you divide to get density
