Can the subscripts in a chemical formula be fractions? Can coefficients in a balanced chemical equation be fractions? Changing the subscripts of chemical can balance the equations mathematically.Why is this unacceptable

Combustion of hydrocarbons such as undecane (C11H24) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid undecane into gaseous carbon dioxide and gaseous water.   2. Suppose 0.310kg of undecane are burned in air at a pressure of exactly 1atm and a temperature of 18.0°C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits. = L

Balance the following chemical reaction. Enter the sum of the balanced coefficients as your answer. Assign "blank" coefficients a value of 1. silver iodide + sodium sulfide → silver sul fide + sodium iodide

What is the mass of the initial sample burned?

Explain the term "limiting reactant". What is an ionic equation? Explain the meaning of "the reaction goes to less than 100% completion".

Ammonia (NH3) is a weak base. Melting point of ammonia is -78 Celsius degrees and boiling point is -33 Celsius degrees. Therefore, pure ammonia appears in gaseous form in room temperature.    a) Preparation of ammonia  Gaseous ammonia (NH3) can be prepared by a reaction where Hydrogen gas  (H2) and Nitrogen gas  (N2) reacts. Write a reaction equation to this reaction. Balance the reaction equation if needed.   b) Behavior of gases Explain the diffusion of gases.   c) Change of temperature The closed container filled with gaseous ammonia is moved from room temperature into a freezer. The temperature on freezer is -35 Celsius degrees. Explain shortly on your own words, what kind of changes does the cooling cause and why.

• Write out the chemical equation for the synthesis of aspirin using ONLY the NAMES of REACTANTS and PRODUCTS!!! (use "+" to separate compounds and "-->" to indicate reactant and product sides of the chemical equation) • Write out the balanced equation for the synthesis of aspirin using chemical formulas: (again use "+" to separate compounds and "-->" to indicate reactant and product sides of the chemical equation, no need for phase labels) • What is the mole ratio of the first reactant and aspirin? What is the mole ratio of the second reactant and aspirin? • Besides aspirin, what its chemical name? The one mentioned in this experiment.

Combustion of hydrocarbons such as nonane (C₂H₂0) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid nonane into gaseous carbon dioxide and gaseous water. C₂H₂0 + 160₂ 9CO₂ + 10H₂0 2. Suppose 0.370 kg of nonane are burned in air at a pressure of exactly 1 atm and a temperature of 13.0 °C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits. OL ローロ X 00 x10
