Answer : The complete net ionic reaction between
and
in an acid solution, can be written as :-
In order to find molarity, you must first find the number of moles that was dissolved.
Now, Moles = Mass ÷ Molar Mass
⇒ Moles of NaCl = 2.922 g ÷ 58.44 g/mol
= 0.05 moles
∴ the Molarity of the NaCl is 0.05 M [Option 1]
HCl is the limiting reactant, and 3.5 mol H2<span> can be formed</span>
Heat energy is absorbed by the substance
B. carbon because it's atomic number is 6
