Which gases contribute to the acid rain formation?

1 answer:

4 0

The main chemicals in air pollution that create acid rain are sulfur dioxide (SO2) and nitrogen (NOx). Acid rain usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. this mixture forms a mild solution of sulfuric acid and nitric acid

Zinc reacts with aqueous sulfuric acid to form hydrogen gas: zn(s) h2so4(aq) ? znso4(aq) h2(g) in an experiment, 201 ml of wet h

WINSTONCH [101]

The products of reaction are ZnSO4 and H2. Since ZnSO4 is in aqueous form (aq), therefore only H2 and water vapor contributes to the overall total pressure in the system.
Total Pressure = 764 torr = H2 partial pressure + Water partial pressure
Since Water partial pressure is 26.74 torr so,
H2 partial pressure = 737.26 torr = 0.97 atm

<h3>What is spectrometric method?</h3>

A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.

There are two main techniques used among the various forms of spectrophotometry:
ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.

Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.

At 50.14k a substance has a vapor pressure of 258.9 torr. calculate its heat of vaporization in kj/mol if it has a vapor pressur

gayaneshka [121]

T₁ = 50,14 K.
p₁ = 258,9 torr.
T₂ = 161,2 K.
p₂ = 277,5 torr.
R = 8,314 J/K·mol.
Using Clausius-Clapeyron equation:
ln(p₁/p₂) = - ΔHvap/R · (1/T₁ - 1/T₂).
ln(258,9 torr/277,5 torr) = -ΔHvap/8,314 J/K·mol · (1/50,14 K - 1/161,2 K).
-0,069 = -ΔHvap/8,314 J/K·mol · (0,0199 1/K - 0,0062 1/K).
0,0137·ΔHvap = 0,573 J/mol.
ΔHvap = 41,82 J.
