We know that the main contributor to greenhouse effect is water vapor, followed by carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). Added to this list are human-made chlorine- and fluorine-containing solvents and refrigerants whose emissions to the atmosphere are regulated through different global initiatives and laws. Give at least 5 simple ways which you can do at home or even during this pandemic which can help reduce the amount of pollutants in the atmosphere and thus may reduce global warming. Limit your answer up to 5 sentences only.

Which of the following statements correctly describes the formation of the ozone hole over Antarctica during the months of spring? The reaction of CFCS and sunlight releases molecules of ozone; in spring, UV rays cause the ozone molecules to release chlorine atoms, which then react to break apart ozone molecules. The reaction of CFCS and sunlight releases atoms of chlorine; in spring, UV rays cause the CFCS to break down and release chlorine atoms, which then react to break apart ozone molecules. The reaction of CFCS and sunlight releases atoms of chlorine; in spring, UV rays cause the CFCS to break down and release chlorine atoms, which then react to break apart ad- ditional CFC molecules. The reaction of CFCS and sunlight releases atoms of chlorine; in spring, UV rays cause the CFCS to combine, and these newly formed molecules react to break apart ozone molecules.

1. What are the three main types of greenhouse gases, what are their respective characterization factors or global warming potential? 2. What is meant by the efficiency of a solar panel (PV) and what are the implications for a solar farm? 3. How is energy extracted from wind and what are the implications for a wind farm? 4. For a wind turbine, what is the impact of the wind speed on the electricity production and how does the design of the wind turbine dictate its efficiency? What control strategies can be used to optimise the performance of wind turbines? How can energy be extracted geothermally. Explain how geothermal energy can be utilised to contribute towards heat demand and what is the role of co-produced water. 5. 6.

5. Suppose the inputs and outputs to the atmospheric carbon reservoir each year were as shown below. How much carbon would the atmosphere contain in ten years? Atmospheric CO, 800 GtC 69 62 Land plants 610 GtC Fossil fuels 69 4881 GtC Oceanic CO, Soil 38000 GtC 2088 GtC A. 780 GtC B. 790 GtC C. 810 GtC O D. 820 GtC

need help with this question please teacher didn’t explain well

How do chemists know that none of the individual Lewis structures of ozone are not accurate depictions of an ozone molecule, and how is this discrepancy addressed?

If there are 1.5 x 109 cows each "passing" on the average 240. Liters of CH4 (g) per day, in one day if all of that CH4 were to be safely collected and undergo a controlled but complete combustion reaction, how many grams of CO2 would contribute to the Greenhouse effect of the Earth?   You will first need to have the combustion reaction of CH4. Make an assumption that the Temperature of the collected gas is 22.4 L = 1 mol, STP conditions (which it really is not at).

Consider the following chemical reaction which produces nitric oxide from its constituent elements: N2 (g) + O2 (g) → 2 NO (g) ArH= 182.6 kJ/mol If nitrogen and oxygen were mixed and allowed to react under constant pressure conditions, which of the following statements must be true? Select as many answers as applicable however points will be deducted for incorrect guesses. The temperature of the surroundings would increase This is an endothermic reaction ΔΗ = ΔU The temperature of the surroundings would decrease ΔΗ = q

Look at the picture and what type of feedback loop it represents?
