Indicate whether aqueous solutions of each of the following solutes contain only ions, only molecules, or mostly molecules and a few ions:

a. NH4Cl, a strong electrolyte.

b. ethanol, C2H6O, a nonelectrolyte.

c.HCN, hydrocyanic acid, a weak electrolyte.

Short Answer

Expert verified

(parta) The aqueous solution of NH4Clcontains only ions.

(part b) The aqueous solution of C2H6Ocontains only molecules.

(part c) The aqueous solution of Hydrocyanic acid(HCN)contains mostly molecules and a few ions.

Step by step solution

01

Introduction (part a)

One or more particles make up a molecule. If those who comprise and over one particle, the atoms can be identical or dissimilar (a water molecule has two hydrogen atoms and one oxygen atom). Any particle or group of atoms with one or more positively or negatively electrical charges is referred to as an ion.

02

Find the aqueous solutions contains molecules or ions (part a).

Given:

NH4Cl, a strong electrolyte.

The NH4Clsolution is a strong electrolyte. Aqueous NH4Clsolutions are mixed only NH4+and Cl-ions. As just a byproduct, a solubility ofNH4Cl will only comprise ions.

03

Find the aqueous solutions contains molecules or ions (part b).

Given:

Ethanol, C2H6O, a non electrolyte.

Ethanol,C2H6Ois a nonelectrolyte solution. C2H6O aqueous sample containing only molecules. As just a result, a solubility of C2H6O will only contain molecules.

04

Find the aqueous solutions contains molecules or ions (part c).

Given:

(HCN), Hydrocyanic acid, a non-electrolyte.

HCN, or hydrocyanic aid, is a nonelectrolyte. Aqueous HCNsolutions are mixed largely HCNmolecules and a few H+and CN-ions. Therefore, an aqueous solution of HCNwill be mostly molecules with a few ions.

Automobile exhaust is a major cause of air pollution. One pollutant is the gas nitrogen oxide, which forms from nitrogen and oxygen caves in the air of the high temperatures in an automobile engine. Once emitted into the air, nitrogen oxide reacts with oxygen to produce nitrogen dioxide, a reddish brown gas with a sharp, pungent odor that makes up smog. One component of gasoline is heptane. C7H16+a liquid which a density of0.684g/mL. In one year, a typical automobile uses 550galof gasoline and produces 411 of nitrogen oxide. (7.4. 7.8.8.6)

a. Write balanced chemical equations for the production of nitrogen oxide and nitrogen dioxide.

b. If all the nitrogen oxide emitted by one automobile is converted to nitrogen dioxide in the atmosphere, how many kilograms of nitrogen dioxide are produced in one year by a single automobile?

c. Write a balanced chemical equation for the combustion of heptane.

d. Horn many moles of gaseous CO2are produced from the gasoline used by the typical automobile in one year, assuming the gasoline is all heptane?

e. How many liters of carbon dioxide at TP are produced in one year from the gasoline used by the typical automobile?

Tamiflu (oseltamivir), C16H28N2O4 is an antiviral drug used to treat influenza. The preparation of Tamiflu begins with the extraction of shikimic acid from the seedpods of star anise. From 2.6g of star anise, 0.13g of shikimic acid can be obtained and used to produce one capsule containing 75mg of Tamiflu. The usual adult dosage for treatment of influenza is two capsules of Tamiflu daily for 5 days.

a. If black spheres are carbon atoms, white spheres are hydrogen atoms, and red spheres are oxygen atoms, what is the formula of shikimic acid?

b. What is the molar mass of shikimic acid?

c. How many moles of shikimic acid are contained in 130g of shikimic acid?

d. How many capsules containing 75mg of Tamiflu could be produced from 155g of star anise?

e. What is the molar mass of Tamiflu?

f. How many kilograms of Tamiflu would be needed to treat all the people in a city with a population of 500000 if each person consumes two Tamiflu capsules a day for 5 days?
