Which of the following is a balanced equation for the combustion of ethanol (CH3CH₂OH)?

What mass of CO2 is produced from the combustion of 1 gal of gasoline? The chemical formula of gasoline can be approximated as C8H18. Assume that there are 2801g of gasoline per gallon.

What mass of water is produced from the complete combustion of 4.70*10-3 g of methane?

magnesium oxide can be produced by heating magnesium metal in the presence of oxygen. When 10.1 g of Mg reacts with 10.5 g of O2, 11.9 g of MgO are collected. What is the balanced equation for this reaction, including all states of matter?

The coefficients in a balanced chemical equation provide the mole-to- mole stoichiometry among the reactants and products. The molar mass (in g/mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. Complete combustion of methane When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH₂(g) + O₂(g) →CO₂(g) + H₂O(g) This type of reaction is referred to as a complete combustion reaction. Review Constants Perio Part A What coefficients are needed to balance the equation for the complete combustion of methane? Enter the coefficients in the order CH4, O2, CO2, and H₂O, respectively. Express your answer as four integers, separated by commas (e.g., 1,2,3,4).

Lithium hydroxide solid is used for removing gaseous carbon dioxide exhaled by astronauts in space vehicles. The products formed are lithium carbonate solid and water. Write a balanced equation for this reaction and calculate how many grams of gaseous carbon dioxide are absorbed by 1.50 g of lithium hydroxide solid.

peact Baking soda is often included in recipes to make food rise. When heated, it will produce sodium carbonate, water vapor, and carbon dioxide. Which of the five types of chemical reactions does the equation represent? Provide evidence and reasoning

Balance the following chemical equation and determine the number of moles of Fe(s) produced when 1 moles of Fe2O3 (s) react with excess C(s) to produce Fe(s) and CO₂ (g). Fe2O3(s) + C(s) → Fe(s) + CO₂(g)

For the following reaction, 6.80 grams of water are mixed with excess chlorine gas. The reaction yields 15.1 grams of hydrochloric acid. chlorine (g) + water (1) →→→→hydrochloric acid (aq) + chloric acid (HCIO3) (aq) What is the theoretical yield of hydrochloric acid ? || What is the percent yield of hydrochloric acid ? grams %

There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: →+2Cu2Ss  3O2g + 2Cu2Os  2SO2g In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: →+Cu2Os  Cs + 2Cus  COg Suppose the yield of the first step is 86.%  and the yield of the second step is  64.% . Calculate the mass of copper(I) sulfide required to make  2.0kg  of copper.   Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.
