The composition of resins is highly variable ; each species produces a unique blend of chemicals which can be identified by the use of pyrolysis – gas chromatography – mass spectrometry.

The hydrogen in the gas reacts with carbonate ions from the electrolyte to produce water, carbon dioxide, electrons and small amounts of other chemicals.

In a chemical equation, the state of matter of the chemicals may be shown as ( s ) for solid, ( l ) for liquid, and ( g ) for gas.

Six waves of ARVN tear gas and attack dogs failed to disperse the crowds, and finally brownish-red liquid chemicals were doused on praying protesters, resulting in 67 being hospitalised for chemical injuries.

Altering the gas composition by adding chemicals can lower the hydrate formation temperature and / or delay their formation.

The detonated shell released only a small amount of sarin gas, either because the explosion failed to mix the binary agents properly or because the chemicals inside the shell had degraded significantly with age.

The exports of Algerian products to Greece amounted to $ 89 million in 2001, including mainly oil and oil derivatives, natural gas, inorganic chemicals, iron and steel.

The region also is a hub for chemicals and gas storage near the port of Quintero.

A leak of methyl isocyanate gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people.

In cases where gas or electric heaters cannot be used due to logistical or economical constraints, anti-icing chemicals can be applied to create a barrier between the metal surfaces of the switch and ice.

The types of weapons employed ranged from disabling chemicals, such as tear gas and the severe mustard gas, to lethal agents like phosgene and chlorine.

This instrument is a versatile gas chemical analyzer that was designed to identify and measure chemicals in Titan's atmosphere.

Koch Pipeline Company LP, which owns and operates of pipeline used to transport oil, natural gas liquids and chemicals.

Survivors said the gas at first smelled of sweet apples ; they said people died in a number of ways, suggesting a combination of toxic chemicals ( some of the victims " just dropped dead " while others " died of laughing "; while still others took a few minutes to die, first " burning and blistering " or coughing up green vomit ).

On 12 March 2008, the government of Iraq announced plans to take further legal action against the suppliers of chemicals used in the poison gas attack.

Current research examines the multiple reaction pathways of pyrolysis to understand how to manipulate the formation of pyrolysis ' multiple products ( oil, gas, char, and miscellaneous chemicals ) to enhance the economic value of pyrolysis ; identifying catalysts to manipulate pyrolysis reactions is also a goal of some pyrolysis research.

Initially developed to produce town gas for lighting & cooking in 1800s, this was replaced by electricity and natural gas, it was also used in blast furnaces but the bigger role was played in the production of synthetic chemicals where it has been in use since the 1920s.

For vehicles, the term propellant refers only to chemicals that are stored within the vehicle prior to use, and excludes atmospheric gas or other material that may be collected in operation.

It is engaged in every aspect of the oil, gas, and geothermal energy industries, including exploration and production ; refining, marketing and transport ; chemicals manufacturing and sales ; and power generation.

Output for the chemicals cluster — which cover oil and gas, petrochemicals and specialty chemicals — totaled S $ 66. 5 billion in 2005, an increase of 31 per cent from 2004.

There were no such gas chemicals being made here.

If the combustion takes place using air as the oxygen source, the nitrogen can be added to the equation, as and although it does not react, to show the composition of the flue gas:

It can react with water to produce flammable hydrogen gas.

The oxygen ions then travel through the electrolyte to react with hydrogen gas at the anode.

Use of water in fire fighting should also take into account the hazards of a steam explosion, which may occur when water is used on very hot fires in confined spaces, and of a hydrogen explosion, when substances which react with water, such as certain metals or hot carbon such as coal, charcoal, coke graphite, decompose the water, producing water gas.

Gases dissolve, diffuse, and react according to their partial pressures, and not according to their concentrations in gas mixtures or liquids.

It is also possible for substances to react with water producing ions, e. g., carbon dioxide gas dissolves in water to produce a solution which contains hydronium, carbonate, and hydrogen carbonate ions.

Many solids react readily with reactive gas species like chlorine, iodine, oxygen etc.

When inoculated to a triple sugar iron ( TSI ) slant, they react as follows: K / A, gas -, H2S -.

In the PBR, thousands of pebbles are amassed to create a reactor core, and are cooled by a gas, such as helium, nitrogen or carbon dioxide, which does not react chemically with the fuel elements.

These acidulants all react with baking soda quickly, meaning that retention of gas bubbles was dependent on batter viscosity and that it was critical for the batter to be baked before the gas escaped.

Nevertheless, nitrogen gas does react with the alkali metal lithium to form compound lithium nitride ( Li < sub > 3 </ sub > N ), even under ordinary conditions.

In addition to aluminium, lye ( sodium hydroxide ) may also react with magnesium, zinc ( galvanized ), tin, chromium, brass, and bronze to produce hydrogen gas and is therefore dangerous.

Silage gas contains nitric oxide ( NO ), which will react with oxygen ( O < sub > 2 </ sub >) in the air to form nitrogen dioxide ( NO < sub > 2 </ sub >), which is toxic.

The term inert gas is context-dependent because nitrogen gas and several of the noble gases can be made to react under certain conditions.

When a voltage is applied to the porous electrode attached to the membrane, the moisture on the anode side ( dehumidifying side ) dissociates into hydrogen ions ( H +) and oxygen: the hydrogen ions migrate through membrane to be discharged on the cathode ( moisture discharging ) side where they react with oxygen in the air, resulting in water molecules ( gas ), being discharged.

These catalysts are not active for NO < sub > x </ sub > reduction because any reductant present would react first with the high concentration of O < sub > 2 </ sub > in diesel exhaust gas.

* Catalytic upgrading of gas by use of hydrogen to react with tarry vapors in the gas

This is necessary to ensure that the blast furnace charge remains porous enough to allow heated gas to pass through and react with the pelletized ore.

Also, the sudden and dramatic reduction in overpressure on the remaining gas charged molten rock in the magma chamber caused it to react by immediately exploding into a super-heated mix of liberated gases and various grades of pulverized and often frothy lava known as a pyroclastic flow.

Acid chlorides evolve hydrochloric acid gas upon contact with atmospheric moisture, are corrosive, react vigorously with water and other nucleophiles ( sometimes dangerously ); they are easily quenched by other nucleophiles besides the desired alcohol ; their most common synthesis routes involve the evolution of toxic carbon monoxide or sulfur dioxide gases ( depending on the synthesis process used ).

The grinding chamber can also be filled with an inert shield gas that does not react with the material being ground, to prevent oxidation or explosive reactions that could occur with ambient air inside the mill.
