How do we measure trace gas pollutants in the atmosphere?

Answers

Answer 1

Answer:

We can measure trace gas pollutants in the atmosphere by using machines or equipments that analysis quantitatively. Examples of these are cyclones, electrostatic precipitator, air bags, venture, absorbers, distillers and many more. They manipulate the properties of these gases in order to extract the pollutants from the clean gas.

4Fe + 3O2à 2Fe2O3 is a balanced equation. What is the charge on each iron (Fe) ion in hematite (Fe2O3)?A. +1
B. +2
C. +3
D. +4

Answers

Answer: The correct answer is Option C.

Explanation:

Oxidation state is the number which is assigned to an element when it gains or looses electrons. If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state.

We take the oxidation state of iron atom be 'x'.

Oxidation state of oxygen atom = -2

Evaluating the oxidation state of iron atom in $Fe_2O_3$ :

$2x+3(-2)=0\n\nx=+3$

Hence, the correct answer is Option C.

+3 I would say, in Fe2O3. O3=-6 Fe=+6 balances to 0

Starting with 100 grams of uranium-238, after one half life has gone by, how many grams of uranium-238 will remain?A._12.5 grams
B._25 grams
C._50 grams
D._100 grams

Answers

Answer : The correct option is, (C) 50 grams

Solution :

Formula used :

$a=(a_o)/(2^n)$

where,

a = amount of reactant left after n-half lives = ?

$a_o$ = Initial amount of the reactant = 100 g

n = number of half lives = 1

Putting values in above equation, we get:

$a=(100)/(2^1)$

$a=50g$

Therefore, the amount of uranium-238 remain will be, 50 g

Answer C, 50 grams.
This is because a half life is the time it takes for a sample of an unstable isotope to spontaneously so that half of the original sample remains

While in Europe, if you drive 107km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 39.0mi/gal ? Assume that 1euro=1.26dollars.

Answers

That's a lot of conversions...
107*7 = 749km in one week
749/1.6 = 468.125 miles
468.125/39 = 12.0032051282 gallons of fuel needed
1 gallon = 4.54609 litres
1.1(Cost per litre)*4.54609(Number of litres per gallon)*12.0032051282(Number of gallons needed) = 60.0244158814 euros cost per week
60.0244158814 * 1.26 = 75.6307640105 dollar cost per week
$75.63

Answer:

$ 62.578

Explanation:

Conversion factors:

1 gal = 3.785 L

1.609km = 1 mi

$1.26 = 1 euro

1 week = 7 days

Converting the car’s mileage from mi/gal to km/L

39 mi/gal x 1 gal/3.785L x 1.609km/1 mi = 16.578 km/L

Finding the L required in a day

107 km x 1L/16.578 km = 6.45 L

Finding the euro spent in day

1.10 euro/L x 6.45 L = 7.095 euro/ day

Finding the euro spent in a week and converting it to dollars

7.095 euro/ day x 7 days x $1.26/ 1 euro = $ 62.578
