Can chemical reactions be reversed? How do you write half reactions? How does mass change during a chemical reaction? Balance the following reaction using any method. Show work. How to tell if a reaction is redox How is an exothermic reaction indicated in an equation?
At even "low" hypersonic speeds (Mach 5-10), air molecules ionize into electrified and chemically reactive plasma, producing exothermic (heat-releasing) reactions that add to already monstrous frictional heat [sources: Fletcher; NASA]. To make it from New York to Los Angeles in 12 minutes ...
Catastrophic failures include thermal runaway events, which can occur when heat generated within a cell triggers an exothermic reaction, releasing more heat and driving further exothermic reactions. When the rate of heat generation exceeds the rate of rejection, the thermal runaway proceeds, which ca...
An exothermic reaction releases energy. At times, it is difficult to remember the difference. Answer and Explanation: The prefixes of the words help one to remember which is which. Thermionic is related to heat, like thermal underwear.You also can remember that that......
How do machines make work easier? Machines: Work is calculated by multiplying the force by the distance. There are two different kinds of machines: simple and complex machines. Simple machines include the pulley, lever and wedge, to name a few. Complex machines include two or more simple mach...
check to see if the motor/compressor has a capacitor; this component is located in a housing on the top of the motor. Capacitors store electricity, even when the power to the unit is turned off. Before you do any work on a capacitor-type refrigerator or freezer, you must discharge the ...
Could you help me by explaining how chemical reactions produce energy and how they cause increases in pressure? Is it beacuse they are exothermic and something to do with bond enthalpies? Thanx :)Crystal Logged Donaldson Tan Editor, New Asia Republic ...
Is esterification reaction exothermic or endothermic? Esterification process can be classified asexothermic reactionwhere in every reaction; a few amount of heat will be released to the surrounding. Hence it is a quite simple reaction; the study on heat releases should not be exceptional. ...
