Explanation:
While the Arrhenius definition of a base agrees with this statement, the Bronsted-Lowry and Lewis definitions don't. Under Bronsted-Lowry, a base is anything that can accept a proton (ex// NH3). Under lewis, it is anything that can donate an electron (ex// Cl-).
Bases are usually bitter and turn red litmus paper blue, and are slippery.
The number of moles of 
form from 5.0 moles 
is 5 moles.
<h3>What is a limiting reactant?</h3>
Limiting reactants are those reactants that are completely used up in a chemical reaction.
4.0 mol will be completely used since the combining ratio is 1 : 1 : 1.
->
From the chemical equation above, 5.0 moles will yield 5 moles of .

Answer:
0.200L of 0.300 Al(OH)₃ are necessaries
Explanation:
A diprotic acid, H₂X, reacts with aluminium (III) hydroxide, Al(OH)₃ as follows:
3 H₂X + 2 Al(OH)₃ → 6H₂O + Al₂X₃
To solve this question we must find the moles of the H₂X, using the balanced reaction we can find the moles of Al(OH)₃ and its volumen knowing its molar concentration is 0.300M:
<em>Moles H₂X:</em>
0.300L * (0.300mol / L) = 0.0900moles H₂X
<em>Moles Al(OH)₃:</em>
0.0900moles H₂X * (2mol Al(OH)₃ / 3mol H₂X) = 0.0600 moles Al(OH)₃
<em>Volume 0.300M Al(OH)₃:</em>
0.0600 moles Al(OH)₃ * (1L / 0.300moles) =
<h3>0.200L of 0.300 Al(OH)₃ are necessaries</h3>
