What can you infer about aspirin’s ester group?
Reil [10]

Answer:

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

  1. carboxylic acid functional group (R-COOH)
  2. ester functional group (R-O-CO-R')
  3. aromatic group (benzene ring)

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

Sulfur dioxide gas, SO2(g), is released from active volcanoes. It reacts in the atmosphere to form sulfur trioxide, SO3(g).
aksik [14]

Explanation:

The reaction given:

2SO2(g) + O2(g) -> 2SO3(g)

A. "The reaction is balanced."

We multiply the sulphur atoms on both sides:

2S -> 2S, ......... 2 sulphur atoms on each side, so balanced.

now oxygen:

2O2+O2 -> 2O3........6 atoms on each side, so also balanced.

This means that the equation is balanced.

B. "When 2 L SO2 react with excess O2, 2 mol SO3 form "

The coefficient of reactant SO2 is 2, so is that of the product.  If we had the same units on either side of the equation (mols, litres, molecules), the statement would have been true.  Since 2L  of SO2 does not contain 2 mol of SO2, so the statement is no longer true.

C. "The coefficients can represent moles, molecules, or liters"

As mentioned in (B) above, we can use moles, molecules or litres (or any other volume unit) to apply to the coefficient and the equation will still be true.  So the statement is true.
