Coal power plants burn large amounts of coal, C(s), in an O₂(g) atmosphere to generate electricity. The chemical reaction responsible for producing this energy is shown below: C(s) + O₂(g) → CO₂ (g) Determine the mass in grams of CO₂ produced when 1.13E2 metric tons of C(s) are completely burned in an O₂ atmosphere (1 metric ton = 10³ kg = 106 g). Don't include units in your answer

3. Determine the enthalpy change (AH₂) for the final reaction below. a. CO(g) + ½ O₂(g) → CO₂(g) AH, -67.6 kcal b. N₂(g) + O₂(g) →→→ 2NO(g) AH₂ = 43.2 kcal c. CO(g) + NO(g) →→→ CO₂(g) + ¹½ N₂(g) AH₂ = ?

When heated, metal hydroxides decompose to produce a metal oxide and water. Selected the correct balanced equation for the decomposition of calcium hydroxide.     CaOH (s) → CaO2 (s) + H2O (g)     Ca(OH)2 (s) → CaO (s) + H2O (g)     2 CaOH (s) → 2 CaO (s) + H2O (g)     3 Ca(OH)2 (s) → 3 CaO2 (s) + H2O (g)

Ethanol, C,H,O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol. The heat of combustion of 2-methylheptane, C3H18, is 1.306×10³ kcal/mol. How much energy is released during the complete combustion of 482 grams of 2-methylheptane ? kcal Assuming the same efficiency, would 482 grams of ethanol provide more, less, or the same amount of energy as 482 grams of 2- methylheptane v more less the same amount

Based on the balance reaction between iron and oxygen, how many electrons are transferred when 27 g of iron react?    balanced reaction: 4Fe(s)+3O2(g)⟶2Fe2O3(s)

Your lab partner accidentally mixed some sodium chloride with your sample of Epsom salts (MgSO₄･7H₂O). You want to make a standard solution of magnesium ion, and this is the only sample of a magnesium salt you have. To determine the amount of magnesium salt in the mixture, you heat 100.00 g to drive off the water of hydration and find that the anhydrous mixture has a mass of 57.75 g. How many grams of the original salt mixture must you add to 1.000 L of water to make a 0.100 M solution of Mg²⁺ ion?
