As weather balloons rise from the earths surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperatura is much lower in the upper atmosphere than at sea level. Would this temperatura effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you?

Propane, C3H8, is a hydrocarbon that is commonly used as a fuel. (a) Write a balanced equation for the complete combustion of propane gas. (b) Calculate the volume of air at 25 C and 1.00 atmosphere that is needed to completely combust 25.0 grams of propane. Assume that air is 21.0 percent O2 by volume. (Hint: we will see how to do this calculation in a later chapter on gasesfor now use the information that 1.00 L of air at 25 C and 1.00 atm contains 0.275 g of 2 per liter.) (c) The heat of combustion of propane is 2,219.2 kJ/mol. Calculate the heat of formation, Hf of propane given that Hf of H2O(l)=285.8 kJ/mol and Hf of CO2(g)=393.5 kJ/mol. (d) Assuming that all of the heat released in burning 25.0 grams of propane is transferred to 4.00 kilograms of water, calculate the increase in temperature of the water.
9.72 Although it can be a nuisance when a laptop computer freezes up and needs to be rebooted, we accept that as somewhat inevitable. But clearly the need to occasionally reboot the control system for the power grid would not be acceptable. Use the web to research ways that engineers ensure the reliability of crucial systems like the control infrastructure of the grid, and write a paragraph summarizing the main strategies employed.

Methane, CH4, can be converted to methanol, which, like ethanol, can be used as a fuel. The energy level diagram shown here presents relationships between energies of the fuels and their oxidation products. Use the information in the diagram to answer the following questions. (The energy terms are per mol-rxn.) (a) Which fuel, methanol or methane, yields the most energy per mole when burned? (b) Which fuel yields the most energy per gram when burned? (c) What is the enthalpy change for the conversion of methane to methanol by reaction with O2(g)? (d) Each arrow on the diagram represents a chemical reaction. Write the equation for the reaction that converts methane to methanol.
The molar heat capacity of a diatomic molecule is 29.1 J/K · mol. Assuming the atmosphere contains only nitrogen gas and there is no heat loss, calculate the total heat intake (in kJ) if the atmosphere warms up by 3.0°C during the next 50 years. Given that there are 2.8 x 10²20 moles of diatomic molecule present, how many kilograms of ice (at the North and South Poles) will this quantity of heat melt at 0° C? (The molar heat of fusion of ice is 6.01 kJ/mol.) Total heat intake: × 10 kJ Ice melted: × 10 |kg (Enter your answer in scientific notation.)
Consider the greenhouse gases, CF2Cl2 and CH2CF2. These have the following properties: CF2Cl2: ΔGfo = -491 kJ/mol, atmospheric lifetime = 102 years, ozone depletion potential = 0.73 CH2CF2: ΔGfo = -451 kJ/mol, atmospheric lifetime = 5.4 years, ozone depletion potential = 0.0 Clearly, CH2CF2 is less hazardous in the atmosphere than CF2Cl2. Is it thermodynamically favorable under standard conditions to react CF2Cl2 with H2 gas to convert it to CH2CF2? (ΔGfo = 0 for H2 and Cl2) CF2Cl2 + H2 ⇌ CH2CF2 + Cl2 Justify your answer and calculate the equilibrium constant for this reaction.
Which statement best describes the cause of the Earth's warming in recent decades? Which one is it? 1. Volcanic eruptions have increased in frequency, causing more greenhouse gases to be emitted. 2. The sun has become brighter, causing the planet to absorb more heat. 3. Greenhouse gases like carbon dioxide have increased in concentration. This has prevented some of the radiation that normally leaves the Earth's atmosphere from leaving, causing the temperature l to increase. 4. The species of plant that normally absorb sunlight have undergone genetic mutations, causing them to emit heat rather than absorb it.
