I think the major difference is that 0.5 is exactly equal to a half. The other 0.555555 is equal to a half plus five hundredths plus thousandths plus five ten thousandths plus five hundred thousandths, plus five millionths and so forth; and therefore it is greater than 0.5. In other words 0.555555 is called a recurring decimal.
Direct titration of aspirin with NaOH have a side reaction simply because aspirin is a weak acid
<h3>What is direct titration?</h3>
Direct titration can simply be defined as a type of titration in which a titrant of known concentration and volume is added to a substance in order to analyze it.
As the name implies, it is called direct titration simply because the one approaches the endpoint of the experiment directly.
Furthermore, the significance of direct titration is that it is used to find the quantity of a substance within a solution with chemical reactions.
So therefore, direct titration of aspirin with NaOH have a side reaction simply because aspirin is a weak acid

A chemist reacted 0. 2 moles sodium benzoate with 0. 25 moles of hydrochloric acid. if she generated 22 g benzoic acid, the percent yield is 90%.
Reactant + HCl ------ Product
0.2 mol 0.25 22g
mol
Number of moles of reactant = 0.2mol
Molar mass of product = 122.12g
Number of moles of product = given mass/ molar mass
= 22g/ 122.12 g
= 0.180mol
Percent yield = (number of moles of product/ number of moles of reactant) × 100
= (0.180/0.2) × 100
= 90%
Thus we concluded that the percent yield of the given solution is 90%.

Answer:
A carbon–carbon bond is a covalent bond between two carbon atoms.
Explanation:
Answer: The concentration of the KOH solution is 1.01 M
Explanation:
According to neutralization law:
where,
= basicity of = 1
= acidity of KOH = 1
= concentration of HCl = 3.00 M
= concentration of KOH = ?
= volume of HCl = 35.3 ml
= volume of KOH = 105.0 ml
Putting the values we get:
Thus the concentration of the KOH solution is 1.01 M
