WebbAcetone absorbs about ____ times its own weight in acetylene. a. 14 c. 34b. 24 d. 44 _B___ 39. The withdrawal rate of gas from a cylinder should not exceed ____ of the total cylinder capacity per hour. a. one-tenth c. one-fifth b. one-seventh d. one-third. _A___40. If more than one torch is to be used with a cylinder, the draw rates of the tips ... The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically. For example, the oxidative rusting of iron under Earth's atmosphere is a slow reaction that can take many y…

WebbDetonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough. Especially for little studied explosives there may be ... WebbThe order of reactivity from fastest to slowest is: combustion, photosynthesis, rusting, weathering. How did you decide which reaction was the fastest and which was the slowest? Answers could include mention of the fact that coal and paper burn fast, whereas rocks do not disappear overnight. can build muscle without supplements

WebbSolution. Activation energies are calculated by subtracting the reactant energy from the transition state energy. diagram (a): E a = 32 kJ − 6 kJ = 26 kJ diagram (b): E a = 20 kJ − 6 kJ = 14 kJ. The catalyzed reaction is the one with lesser activation energy, in this case represented by diagram b. Webbof combustion processes, the temperature in the zone of chemical reactions is high. In this case, the delivery of the oxidizing agent is, as a rule, the slowest process, just which … Webb1 feb. 2013 · The combustion characteristics can be analysed by combustion indicators like max. in-cylinder pressure (Pmax), heat release rate (HRR), combustion duration (CD) and ignition delay (ID). fishing marine warehouse
