Q:Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?

What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC

Q:What is organic matter?

Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q:Is carbon monoxide an organic gas?

Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.

Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?

Hydrocarbon derivatives of oxygen in the standard conditions are gaseous formaldehyde.

Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?

Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.

Q:Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?

Not a polymer can not be considered a saturated hydrocarbon derivatives. Natural oils contain unsaturated structures

Q:Is the plexiglass intermediate?

Acrylic acid and its ester polymerization of the polymer obtained collectively referred to as acrylic resin, the corresponding plastic collectively referred to as polyacrylic plastic, in which the most widely used polymethyl methacrylate. Poly methyl methacrylate abbreviation for the PMMA , Commonly known as plexiglass, is so far the most transparent synthetic material quality.

Q:The role of aromatic hydrocarbons

Aromatic hydrocarbons referred to as "aromatic hydrocarbons", usually refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed-chain type. With the basic structure of the benzene ring, the history of the early discovery of such compounds have more aromatic flavor, so called these Hydrocarbons are aromatic hydrocarbons, and hydrocarbons that are later found to have no aromatic flavor are also commonly used in this way, such as benzene, naphthalene, etc. The homology of benzene is CnH2n-6 (n≥6).

Q:Compare the difference between London smoke and Los Angeles photochemical smog

Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

Q:Which acid is strong for carboxylic acid and carbonic acid?

Carbonic acid is strong.
