Provide a balanced chemical equation for the production of the II-IV semiconductor CdS from the reaction of dimethylcadmium [Cd(CH₃)₂] and diethyl sulfide [(C₂H₅)₂S]. The byproducts of the reaction are ethane (C₂H₆) and butane (C₄H₁₀).

An unknown hydrocarbon is composed of only C and H. When 1 volume of the hydrocarbon is combusted with 5 volumes of O₂, this results in the formation of 3 volumes of CO₂ and 4 volumes of water vapor. Determine the formula of the unknown hydrocarbon and write a balanced chemical equation for the reaction.

Esters are organic compounds that are known for their pleasant smell. They can be produced through an organic reaction called the Fischer esterification, where carboxylic acids react with an alcohol to form the ester.

Write the balanced reaction equation for the formation of ethyl hexanoate, an ester with a pineapple-like odor, where R₁ = CH₃CH₂CH₂CH₂CH₂— (pentyl group) and R₂ = CH₃CH₂— (ethyl group).

The following illustration shows a hypothetical reaction between A (green spheres) and B (white spheres):

Which of the following best represents the reaction above?

(a) A₂ + 3 B₂ → 2 AB₃

(b) 3 A₂ + 9 B₂ → 3 AB₃

(c) A + 3 B → AB₃

Balance the following chemical equation: Co(NO₃)₃(aq) + (NH₄)₂CO₃(aq) → Co₂(CO₃)₃(s) + NH₄NO₃(aq)

Calculate the sum of the coefficients for the balanced reaction for the complete combustion of propionic acid, C₃H₆O₂

Write the balanced chemical equation showing the formation of aqueous nitric acid, a component of acid rain, from gaseous nitrogen dioxide, gaseous oxygen, and liquid water. (Note: This is a simplified form of the reaction.)
