Q: What are compounds composed of only two elements called? Read this paragraph and choose the correct option from the provided answers: Binary compounds are compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Choices: - digital compounds - symbiotic compounds - kinetic compounds - binary compounds A:
binary compounds

Q: What are prepared by the oxidation of secondary alcohols? Read this paragraph and choose the correct option from the provided answers: The carbonyl group, a carbon-to-oxygen double bond, is the defining feature ofaldehydes and ketones. In aldehydes at least one bond on the carbonyl group is a carbon-to-hydrogen bond; in ketones, both available bonds on the carbonyl carbon atom are carbon-to-carbon bonds. Aldehydes are synthesized by the oxidation of primary alcohols. The aldehyde can be further oxidized to a carboxylic acid. Ketones are prepared by the oxidation of secondary alcohols. Mild oxidizing agents oxidize aldehydes to carboxylic acids. Ketones are not oxidized by these reagents. A thiol is a compound with an SH functional group. Choices: - protons - more alcohol - ions - ketones A:
ketones

The subclass in which the human species is classified is the placental mammals. Choices: - somatic mammals - marsupial mammals - respiratory mammals - placental mammals A:
placental mammals
