Answer:
"2.48 mole" of H₂ are formed. A further explanation is provided below.
Explanation:
The given values are:
Mole of Al,
= 3.22 mole
Mole of HBr,
= 4.96 mole
Now,
(a)
The number of mole of H₂ are:
⇒ 
or,
⇒ 
⇒ 
⇒ 
(b)
The limiting reactant is:
= 
(c)
The excess reactant is:
= 
Reducing the volume of contained gas by one third, while holding temperature constant, causes pressure to D. be increased by one third
The end result will be inaccurate as the concentration of the acid or base being calculated will be more concentrated than it actually is due to the endpoint being surpassed
Periodic table!
The periodic table organizes elements by their chemical properties (mainly through vertical columns known as groups) and increasing atomic number.
Icy water is just water.
It is a compound.
