The balanced chemical equations for the two described reactions are to be written. Concept Introduction: Chemical equations having an equal number of atoms of each type on both sides of the equation is known as a balanced chemical equation. The steps to balance chemical equation are: If there is an element that occurs in only one compound on both sides of the equation, balance it first. If there are more than one such element is there, balance metals before non-metals. If the element is present in a free state on both the sides of the equation, balance it last. These elements are balanced by adjusting the coefficients. If coefficients are present in a fraction, convert it into whole numbers by multiplying with the appropriate number.

The world burns approximately 3.7 * 1012 kg of fossil fuel per year. Use the combustion of octane as the representative reaction and determine the mass of carbon dioxide (the most significant greenhouse gas) formed per year. The current concentration of carbon dioxide in the atmosphere is approximately 399 ppm (by volume). By what percentage does the concentration increase each year due to fossil fuel combustion? Approximate the average properties of the entire atmosphere by assuming that the atmosphere extends from sea level to 15 km and that it has an average pressure of 381 torr and average temperature of 275 K. Assume Earth is a perfect sphere with a radius of 6371 km.

The Earth’s atmosphere was mainly composed of ammonia, methane, and water three billion or four billion years ago. What could be the reason why at present ammonia and methane have largely disappeared and water has maintained its concentration? a. Ammonia and methane reacted with each other forming nitrogen, oxygen, and carbon dioxide b. Water vapor in the atmosphere is inert, that is, it does not react with other substances c. Big volume of nitrogen, oxygen, and carbon dioxide was vented out from the Earth’s interior d. Ammonia and methane are more reactive than water

Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.19 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 165-L tank at −45.0°C, what is the final pressure in the tank? (MPa)
