<u>Answer:</u>

<em>15.36 moles of carbon dioxide are produced when 5.12 mol of propane gas is burned in excess oxygen</em>

<u>Explanation:</u>

The Balanced Chemical equation is :

C_3 H_8 (g) + 5O_2 (g) > 3CO_2 (g) + 4H_2 O(l)

Mole ratio of C_3 H_8:CO_2 is 1 : 3

That is, 1 mole of propane gas produces 3 moles of carbon dioxide gas.

Using mole ratio we can solve this  

5.12mol C_3 H_8  \times \frac {(3mol CO_2)}{(1mol C_3 H_8 )}

=15.36 mol CO_2 is produced.

(Answer)

<u>Please note  :</u>

To convert moles to mass, we multiply by molar mass  

To convert mass to moles, we divide by molar mass

Molar mass is the mass of 1 mole of the substance

For example molar mass of CO_2 is

(12.0+2\times16)=44 g/mol

(we just add the atomic mass of the atoms to get the molar mass of the substance)

ivolga24 [154]

Answer:

1.7 ppm

Explanation:

Original amount N' = 2.6 ppm

time to testing t = 24 hr

final amount N = 2.1 ppm

Using exponential inhibited decay, we have

N = N'e^(-kt)

Where

N is the new reading

N' is the original reading

t is the decay time

k is the decay constant

Substituting, we have

2.1 = 2.6 x e^(-k x 24)

2.1 = 2.6 x e^(-24k)

0.808 = e^(-24k)

We take the natural log of both sides of the equation

Ln 0.808 = Ln (e^(-24k))

-0.213 = - 24k

K = 0.213/24 = 0.00886

After 48 hrs, the reading of free chlorine will be

N = 2.6 x e^(-0.00886 x 48)

N = 2.6 x e^(-0.425)

N = 2.6 x 0.654

N = 1.7 ppm

What form of pollution can lichens be a good indicator of?
Natasha2012 [34]

Answer:

Lichens can be used as air pollution indicators, especially of the concentration of sulphur dioxide in the atmosphere. Lichens are organisms that grow in exposed places such as rocks or tree bark. They need to be very efficient at absorbing water and nutrients to grow there.
