How can people reduce respiratory Diseases & Accidents?

Chemistry
1 answer:
kirill [66]3 years ago
6 0

Respiratory diseases can be prevented. Avoiding exposure to tobacco smoke, home and workplace air pollutants, and respiratory infections can prevent the development of COPD. Smoking is the most common cause of chronic respiratory diseases like COPD. Smoking cessation is the most important part of treatment for smokers diagnosed with chronic respiratory disease. Indoor and outdoor air pollutants cam also cause respiratory problems. Air pollution can irritate, inflame, or destroy lung tissue. Washing hands regularly with soap and water can prevent respiratory infections. It is estimated that hands spread 80 percent of common infectious respiratory diseases like colds and flu. Early detection of respiratory diseases might change disease course and progress. A simple test, called spirometry can be used to measure pulmonary—or lung—function and detect COPD in anyone with breathing problems.

Hope this helps!

What pressure (in atmospheres) does a gas exert when at 385 mm of Hg?
Westkost [7]
To find out the pressure in atm. You must divide 385 by 760. So pressure in atmospheres equals 385/760.

The maximum number of electrons in a single d subshell is:
Iteru [2.4K]

10 electrons

Explanation:

The maximum number of electrons in a single d-subshell is 10 electrons.

The d-sub-orbital used to denote azimuthal or secondary quantum numbers.

The maximum number of electrons in the orbitals of sublevels are:

    two electrons in the s-sublevel, it has one orbital

   

   six electrons in the p-sublevel, it has three orbital

   ten electrons in the d- sublevel, it has five orbitals

   

   fourteen electrons in the f-sublevel, it has seven orbitals

The maximum number of electrons in an orbital is two.

The average adult male has a total blood volume of 5.0 L. After drinking a few beers, he has a BAC of 0.10. What mass of alcohol
stellarik [79]
  B A C ( Blood Alcohol Content ) of 0.10 means that there are 0.10 g of alcohol for every  dl  of blood.
  5 L = 50 dl
  50 * 0.10 g = 5 g
  In his blood is circulating 5 grams of alcohol.

Ammonia NH3 may react with oxygen to form nitrogen gas and water.4NH3 (aq) + 3O2 (g) \rightarrow 2 N2 (g) + 6H2O (l)If 2.15g of
bagirrra123 [75]

Answer:

NH3 is the limiting reactant

The % yield is 36.1 %

Explanation:

<u>Step 1: </u>Data given

Mass of NH3 = 2.15 grams

Mass of O2 = 3.23 grams

Molar mass of NH3 = 17.03 g/mol

Molar mass of O2 = 32 g/mol

volume of N2 produced = 0.550 L

Temperature = 295 K

Pressure = 1.00 atm

<u>Step 2:</u> The balanced equation:

4NH3 (aq) + 3O2 (g) → 2 N2 (g) + 6H2O (l)

<u>Step 3:</u> Calculate moles of NH3

Moles NH3 = Mass NH3 / Molar Mass NH3

Moles NH3 = 2.15 grams / 17.03 g/mol

Moles NH3 = 0.126 moles

<u>Step 4:</u> Calculate moles of O2

Moles O2 = 3.23 grams / 32 g/mol

Moles O2 = 0.101 moles

<u>Step 5: </u>Calculate the limiting reactant

For 4 moles NH3 consumed, we need 3 moles of O2 to produce, 2 moles of N2 and 6 moles of H2O

NH3 is the limiting reactant. It will completely be consumed ( 0.126 moles).

O2 is in excess, there will be 3/4 * 0.126 = 0.0945 moles consumed

There will remain 0.101 - 0.945 = 0.0065 moles of O2

<u>Step 6:</u> Calculate moles of N2

For 4 moles NH3 consumed, we need 3 moles of O2 to produce, 2 moles of N2 and 6 moles of H2O

For 4 moles NH3 , we'll have 2 moles of N2 produced

For 0.126 moles NH3 consumed, we'll have 0.063 moles of N2 produced.

<u>Step 7</u>: Calculate volume of N2 produced

p*V = n*R*T

⇒ with p = the pressure of the gas = 1.00 atm

⇒ with V = the volume = TO BE DETERMINED

⇒ with n = the number of moles N2 = 0.063 moles

⇒ with R = the gasconstant = 0.08206 L*atm/K*mol

⇒ with T = the temperature = 295

V = (nRT)/p

V = (0.063*0.08206*295)/1

V = 1.525 L = theoretical yield

<u>Step 8:</u> Calculate the % yield

% yield = actual yield / theoretical yield

% yield = (0.550 L / 1.525 L)*100%

% yield = 36.1 %
