An
exothermic reaction ensues with darkening of mixture and completed almost immediately as confirmed by TLC.
By changing the composition, the reactivity, the heat and the chemistry of the
exothermic reaction changed.
The product of the Prater number, which is positive for
exothermic reactions, and the intrapellet Damkohler number essentially represents a ratio of the rate of thermal energy generation due to chemical reaction relative to the rate of thermal conduction (i.
The torrential rain caused some water to seep into a perforated drum which caused an
exothermic reaction,' said Bill Gough, of West Midlands Fire Service.
Binder material is removed via evaporation and
exothermic reaction, rather than with potentially hazardous solvents.
During curing the
exothermic reaction may raise the temperature by about 80 [degrees]C, depending upon the amount of hardener used.
And unlike methyl methacrylate, hydroxyapatite cement causes no
exothermic reaction during the setting phase.
HotHands packets contain a mixture of powdered iron, salt water, activated charcoal and vermiculite, which cause a heat-producing
exothermic reaction when exposed to air.
The resulting
exothermic reaction consistently generates temperatures in excess of 155 degrees, thereby destroying pathogens.
Localized heating and rapid quenching of this highly
exothermic reaction prevents damage to the catalyst surface which, in conventional regeneration processes, is usually caused by prolonged exposure to high temperatures.
The reaction of the sugars' carmelization generates its own heat in the form of an
exothermic reaction.
The alkalinity of cement is due to the
exothermic reaction of calcium oxide with water, which forms calcium hydroxide.
