HCl is the limiting reactant, and 3.5 mol H2<span> can be formed</span>
I would choose C bc if u look at it closely u can notice it goes up steadily and then BANG it decreases a lot
Answer:
Explanation:
Dalton’s Atomic Theory
All elements are composed of tiny indivisible particles called atoms.
All atoms of the same element are identical.
Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).
Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).
Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).
A 25.00 ml sample of hydrochloric acid solution, HCl, is titrated with 0.0512 m NaOH solution. the volume of NaOH solution required is 21.68 ml then the molarity of the HCl solution is 0.044 M .
Calculation ,
Formula used : 
...( i )
Where M is the molarity or concentration and V is the volume in ml .
concentration of hydrochloric acid solution ( 
) = ?
concentration of NaOH ( 
) = 0.0512 M
volume of hydrochloric acid solution ( 
) = 25.00 ml
volume of NaOH ( 
) = 21.68 ml
Putting the value of concentration , volume of both in equation ( i ) we get .
× 25.00 ml = 0.0512 × 21.68 ml
= 0.0512 × 21.68 ml / 25.00 ml= 0.044 M
