N2 and O2 are the two largest components of the atmosphere by mixing ratio. Explain why they have a global warming potential of zero, while trace gases like CO2 and CH4 have non-zero global warming potentials.

Ancient Romans built often out of bricks and mortar. A key ingredient in their mortar was quicklime (calcium oxide), which they produced by roasting limestone (calcium carbonate). 1. Write a balanced chemical equation, including physical state symbols, for the O-0 decomposition of solid calcium carbonate (CaCO3) into solid calcium oxide and gaseous carbon dioxide. x10 Ar 2. Suppose 86.0L of carbon dioxide gas are produced by this reaction, at a temperature of 230.0 °C and pressure of exactly 1 atm. Calculate the mass of calcium carbonate that must have reacted. Be sure your answer has the correct number of significant digits.

Oxalic acid C2H2O4 is a metabolic product of many molds. Although oxalic acid is toxic to humans if ingested, many plants and vegetables contain significant amounts of oxalic acid or oxalate salts. In solution, oxalic acid can be oxidized by air via the following chemical equation: H2C2O4 (aq) + O2 (g) -> H2O2 (l) + 2 CO2 (g) If a plant metabolized enough oxalic acid to produce 3.2L of CO2​ on a day when the temperature was 29°C and the pressure was 752 mmHg,   a) how many grams of oxalic acid were converted to CO2​? b) Given that air is 2121% oxygen, what volume of air was needed for the oxidation?

The Haber Process, developed by Fritz Haber in 1909, was a revolutionary method for producing ammonia from elemental hydrogen and nitrogen on an industrial scale. Write a balanced equation showing the conversion from elemental nitrogen (N2) and hydrogen (H2) to ammonia (NH3). (Omit states-of-matter from your answer.)

How does CaO or CaCO2 remove SO2 from flue gases?

Give explanation of the correct option and explanation of the incorrect options. Hand written solutions strictly prohibited.

The airbags that protect people in car crashes are inflated by the extremely rapid decomposition of sodium azide, which produces large volumes of nitrogen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (NaN,) into solid sodium and gaseous dinitrogen. alb Ar 2. Suppose 12.0 L of dinitrogen gas are produced by this reaction, at a temperature of 13.0 °C and pressure of exactly 1 atm. Calculate the mass of sodium azide that must have reacted.

Which of the following statements is false concerning the reaction of hydrogen gas and oxygen g below? H₂(g) + O₂(g) → H₂O(); AH = -285.8 kJ Per mole of O2, the change in enthalpy is -571.6 kJ. The value-571.6 kJ pertains to 1 mol of liquid water. O If the equation is multiplied by 2, AH becomes -571.6 kJ. O For the reaction H₂(g) + O2(g) → H₂O(g), AH is not equal to -285.8 kJ. If the equation is reversed, AH becomes +285.8 kJ.

What volume (in mL) of 3.20 M HNO3(aq) needs to be added to excess Na,CO3(s) to generate 4.85 L CO2(g) at standard temperature and pressure (STP)? Provide your answer in decimal notation rounded to the appropriate number of significant figures.
