Short Answer

Expert verified

Part a) As a result, a red blood cell will not alter.

Part b) A red blood cell will crenate as a result.

Part c) As a reaction, hemolysis occurs in a red blood cell.

Part d) As a corollary, a red blood cell will remain unchanged.

Part e) As an outcome, hemolysis occurs in a red blood cell.

Step by step solution

01

Introduction.(Part a)

Depending on the osmotic pressure of the medium in which it is placed, a red blood cell will experience crenation, hemolysis, or no change.

Because there is an equal flow of water in and out of a red blood cell in an isotonic solution, the cell preserves its volume. A solution and a 5%(m/v)glucose solution serve as isotonic solutions.

02

Given data (Part a).

Water rushes into red blood cells when they are placed in a solution, causing them to inflate and burst. Hemolysis is the name for this process. The amount of solute in a hypotonic solution is lower.

Water leaves a red blood cell when it is added to the solution, leading it to shrink. Crenation is the term for this procedure. The amount of solute in a hypertonic solution is higher.

03

Explanation (Part a). 

The form of a red blood cell in isotonic, hypotonic, and hypertonic solutions is depicted in the diagram below:

Isotonicity is defined as a 0.9%(m/v)NaClsolution. As a result, a red blood cell will remain unchanged. As a result, the diagram depicting the form of a red blood cell in a 0.9%(m/v)NaClsolution is

04

Given data (Part b).

(b) In comparison to a 5%(m/v)glucose solution, a 10%(m/v)glucose solution has a larger solute concentration. As a result, a 10%(m/v)glucose solution is hypertonic. A red blood cell will crenate as a result.

05

Explanation (Part b). 

As a result, the diagram depicting the form of a red blood cell in a10%(m/v)glucose solution is.

06

Given data (Part c).

(c) When contrasted to a 0.9%(m/v)NaClsolution, a 0.01%(m/v)NaClanswer has a lower osmotic pressure. As a result, a NaClsolution of 0.01%(m/v)is hypotonic. As a result, hemolysis occurs in a red blood cell.

07

Explanation (Part c).

Therefore, the diagram that represents the shape of a red blood cell when placed in a 0.01%(m/v)NaClsolution is

08

Given data (Part d).

(d) A glucose solution containing 5%(m/v)glucose is isotonic. As a result, a red blood cell will stay unchanged.

09

Explanation (Part d).

As a corollary, the image showing the size of a red blood cell in a 5%(m/v)glucose solution is as follows:

10

Given data (part e).

(e) When opposed to a 5%(m/v)glucose solution, a 1%(m/v)sucrose solution has a lower osmotic pressure. A 1%(m/v)glucose solution is therefore hypotonic. As a result, hemolysis develops in a red blood cell.

11

Explanation (Part e).

As a result, the diagram illustrating the form of a red blood cell in a 1%(m/v)glucose solution is.

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?
