Review of Short Phrases and Links

Heating

  1. The heating or chilling effects associated with exothermic or endothermic reactions can positively or negatively affect theoperation of the reaction zone. (Web site)

Steam

Mixed

  1. Mixed with water it causes an exothermic reaction. (Web site)

Steps

Vigorous

  1. Forms a vigorous, highly exothermic reaction. (Web site)
  2. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.

Violent

  1. POCI 3 and water, when combined, will form hydrochloric acid and will produce a violent, exothermic reaction. (Web site)
  2. The reaction is notably more violent than that of lithium or sodium with water, and is sufficiently exothermic that the evolved hydrogen gas ignites. (Web site)

Explosion

  1. The reaction is highly exothermic, and can lead to an explosion.

Cooling

  1. The halogenation reaction is mildly exothermic and heating or cooling may be employed to facilitate appropriate reaction temperature control.

Addition

  1. After addition of 115g anhydrous K2CO3 and 125g methyl iodide, the solution came to reflux due to an exothermic reaction. (Web site)

Case

  1. In some case, the nitrogen is expected to act as a dilution gas since the reaction is exothermic. (Web site)

Formation

  1. The formation of a solution is favoured if the balance in terms of energy change between the two steps is exothermic.

Polymerization

  1. Since the polymerization reaction is exothermic, these blowing agents volatilize into a gas during the reaction process.

Air

  1. Our example reaction is exothermic, which we already know from everyday experience, since burning gas in air gives off heat. (Web site)

Exhaust System

  1. As such, under some conditions, there may be an exothermic reaction in the exhaust which generates heat in the exhaust system. (Web site)

Oxygen

  1. Solid-oxide fuel cells produce exothermic heat from the recombination of the oxygen and hydrogen. (Web site)
  2. Oxidation Burning in oxygen, normally highly exothermic (heat releasing), but also any increase in oxidisation state, (i.e.

Fuel Cell

  1. This is particularly challenging as the 2H 2 + O 2 - 2H 2 O reaction is highly exothermic, so a large quantity of heat is generated within the fuel cell. (Web site)

Place

  1. Although the overall hydrogenation reaction is exothermic, a high activation energy prevents it from taking place under normal conditions. (Web site)

Favourable

  1. An exothermic reaction is more favourable and thus more likely to occur.

Thermal Energy

  1. In addition to the thermal energy that may be released by an exothermic reaction, the reaction mixture can be appropriately heated. (Web site)

Binding Energy

  1. We found that the formation of the complex is exothermic and its binding energy is extremely large. (Web site)

Combustion

  1. If we go back to combustion and the formation of water, it is also an exothermic reaction of nature loosely analogous to fusion. (Web site)

Combustion Process

  1. AIR was used to lower exhaust emissions by injecting warm, fresh air into the combustion process to create an exothermic reaction.

Chemical Reactions

  1. The first group consists of devices using endothermic or exothermic chemical reactions for producing a chilling effect or a heating effect respectively. (Web site)
  2. As in chemical reactions, nuclear reactions can either be exothermic (i.e. (Web site)
  3. Chemical reactions are either endothermic or exothermic. (Web site)
