What is acid rain? Which fossil fuel causes acid rain? What are the chemical reactions that produce the acid?
Ahat [919]

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

When we burn the coal that produce sulfur dioxide .

the molecular weight of the nitrous oxide is 44.013 g/mol. assuming standard temperature and pressure, what would be the volume,
allsm [11]

The volume of the nitrous oxide gas is 1729.3 Liters

<h3>What is the number of moles of gas present in 3.40 kg of nitrous oxide?</h3>

The number of moles of gas present in 3.40 kg of nitrous oxide is determined from the formula below:

Numbers of moles = mass/molar mass

the mass of nitrous oxide = 3.40 kg or 3400 g

the molar mass of nitrous oxide = 44.013 g/mol

Moles of gas = 3400 / 44.013

Moles of gas = 77.25 moles

Using the ideal gas equation to determine the volume of the gas:

PV= nRT

V = nRT/P

where;

  • V is the volume of gas
  • n is the number of moles of gas
  • R is molar Gas constant = 0.082 L.atm/mol/K
  • T is the temperature of the gas

V = 77.25 * 0.082 * 273 / 1

The volume of the gas = 1729.3 Liters

The weather in Europe was unusually warm during the summer of 1995. The TV news reported temperatures as high as 45 degree centi
Tpy6a [65]

Answer : The temperature on the Fahrenheit scale was, 113^oF

Explanation :

The conversion used for the temperature from degree centigrade to Fahrenheit is:

^oF=(^oC\times \frac{9}{5})+32

where,

^oF = temperature in Fahrenheit

^oC = temperature in centigrade

As we are given the temperature in degree centigrade is, 45

Now we have to determine the temperature in Fahrenheit.

^oF=(45^oC\times \frac{9}{5})+32

^oF=113

Therefore, the temperature on the Fahrenheit scale was, 113^oF
