Hope this helped
I think the correct answer from the choices listed above is the first option. She concluded that the reaction is an exothermic one because t<span>he reaction released heat. Exothermic is when heat goes out of the system. The opposite is referred to as an endothermic reaction.</span>
Answer: 2.408×10^24 atoms
Explanation:
Applying the formula
No. moles= (no. Of atoms)/Avogadro's number
4 = n/6.02×10^23
no. of atoms= 2.408×10^24 atoms
8.04 mL.
<h3>Explanation</h3>
How many moles of NaOH?
Note the unit:

.
How many moles of HCl?
As seen in the equation, HCl and NaOH reacts at a 1:1 ratio.
.
How many mL of HCl?
