The answer is B) the second group
The complete reaction is as,
4-Aminophenol + Acetic Anhydride → <span>Acetaminophen + Acetic Acid
First of all convert the ml of Acetic anhydrite to grams,
As,
Density = mass / volume
Solving for mass,
mass = Density </span>× Volume
<span>Putting values,
mass = 1.08 g/ml </span>× 5ml
<span>
mass = 5.4 g of acetic anhydride
First Find amount of acetic anhydride required to react completely with 2 g of p-Aminophenol,
As,
109.1 g of p-aminophenol required = 102.1 g of acetic anhydride
so, 2 g of p-aminophenol will require = X g of Acetic Anhydride
Solving for X,
X = (2 g </span>× 102.1 g) ÷ 109.1 g
X = 1.87 g of acetic anhydride is required to be reacted.
But, we are provided with 5.4 g of Acetic Anhydride, means p-aminophenol is the limiting reactant and it controls the formation of product. Now Let's calculate for product,
As,
109.1 g of p-aminophenol produced = 180.2 g of <span>Acetaminophen
So 2.00 g of p-aminophenol will produce = X g of Acetaminophen
Solving for X,
X = (2.00 g </span>× 180.2 g) ÷ 109.1 g
X = 3.30 g of Acetaminophen
Result:
<span>If 2.00g of p-aminophenol reacts with 5.00 ml of acetic anhydride 3.30 g of acetaminophen is made.</span>
The electron-dot formula of the hydrogen chloride HCl is shown in the attached diagram below.
<h3>What is the lewis electron dot diagram?</h3>
A lewis electron dot structure can be used to express the number of bonds, the bonding atoms, and the lone pairs remaining in the atoms in the molecule.
Lines are represented between atoms that are bonded with each other and excess electrons or lone pairs are shown as dot pairs and are placed next to the atoms.
As the valence electrons in the chlorine atom are equal to 7 from the electronic configuration of the chlorine atom. First, the total number of valence electrons in the HCl molecule is 7 + 1 = 8.
A chlorine atom requires only one electron to complete its octet configuration. As the octet completes, the rest of the electrons of Cl are assigned as the lone pairs of the Cl atom. Therefore, the chlorine atom has 3 lone pairs of electrons on it and the hydrogen atom completes its duplet.

First calculate how many moles of O2 you have. O is 16g/mole, so O2 is 32g/mole. 50/32 = 1.5625 moles. 1 mole of any gas at stp is 22.4 liters.
1.5625 × 22.4 = 35 liters.
Its been 15 years since I graduated HS, and I still remember how to do this. Do your own homework next time and in 15 years you may be able to do the same. ;)

The pressure of gas will increase because gaseous state is the final state and even if the heat added is evaporating some more gas is still added. It also depends on the temperature of heat added, if the temperature doesn't change the it's most likely for the pressure to be stable...
Hope it helps
