Oxides in a sentence

Chesterman and Lowe, p. 383 Oxides main Oxide minerals are divided into three categories: simple oxides, hydroxides, and multiple oxides.

Also, gas does not produce nitrogen oxides (NOx) and sulfur oxides (SOx) which cause acid rain and air pollution.

Combustion of LNG emits fewer nitrogen oxides and very few soot particles or sulfur oxides.

Examples of oxides The following table gives examples of commonly encountered oxides.

Oxides Curium readily reacts with oxygen forming mostly Cm 2 O 3 and CmO 2 oxides, but the divalent oxide CmO is also known.

The chemical effects of this increase in electronegativity can be seen both in the structures of oxides and halides and in the acidity of oxides and oxoacids.

The clays of a soil are a mixture of the various types of clay, but one type predominates.sfn There are four groups of clay: layer silicates; crystalline chain silicates; metal oxides and hydroxides and oxy-oxides; and amorphous; and allophanes.

They form various types of oxides, such as simple oxides (containing the O 2− ion), peroxides (containing the Omain ion, where there is a single bond between the two oxygen atoms), superoxides (containing the Omain ion), and many others.

This kind of visible air pollution is composed of nitrogen oxides, sulfur oxides, ozone, smoke or particulates among others (less visible pollutants include carbon monoxide, CFCs and radioactive sources).

And the chemistry-based model enabled the researchers to track secondary pollutants, such as ozone, which is formed when nitrogen oxides (NOvolatile organic compounds (VOCs) emissions are exposed to sunlight.

For petrol cars, the required standard is Euro 4 (for nitrogen oxides, or NOx) and for diesel cars, it’s Euro 6 (for both NOx and particulate matter, or PM).

Identify the minerals observed: The Manganese minerals observed are limited to a suite of manganese oxides, hydroxides, carbonates, and silicates.

The magnitude of the effects of nitrogen oxides on lumbar spine BMD would amount to 1.22 per cent annual reductions — nearly double the annual effects of age on any of the anatomical sites evaluated.

They occur as oxides, or “earths” in the old chemical jargon, and they are not really so rare.

A combination of heavy and light rare earth oxides, excluding cerium and yttrium.

Becker provided a detailed overview of the expected impact of the clean car standards, noting significant reductions in nitrogen oxides and particulate matter, which contribute to ozone formation and affect respiratory health.

Gossans are typically rust-coloured oxides and hydroxides of iron and manganese which are derived by weathering oxidation.

Other compounds, including nitrogen oxides, can also harm plants and reduce photosynthesis.

Production areas contain lower head grades and a higher presence of ferrous oxides in the upper levels, which impacted recoveries by approximately 2% in the quarter.

Some of these findings include the discovery of manganese oxides on Mars in 2016, which indicates that higher levels of atmospheric oxygen could have once existed there.
