Why are exothermic reactions useful? Why are mycorrhizae important? Why is the water molecule so important to organisms? Why is deuterium used in NMR? Why is chemistry important in the study of biology? Why is the queen bee so important?
Exothermic reactions are reactions that realese energy while a chemical reaction takes place. Energy will be released in the form of heat, transferring energy to its surroundings. Most exothermic reactions are spontaneous, but some other require certain conditions in order to trigger. One clear ...
Which actions are evidence that a chemical reaction has occurred choose all that apply? Evidence of a chemical change Change of odor. Change of color (for example, silver to reddish-brown when iron rusts). Change in temperature or energy, such as the production (exothermic) or loss (endother...
It’s more effective than conventional carbons; catalytic activity promotes a variety of chemical reactions It has a faster chemical reaction means less carbon and smaller equipment Non-Impregnated carbon eliminates worries about exothermic reaction, ignition temperature and toxic disposal ...

Why are chemical reactions useful? Why is the bicarbonate in blood an effective buffer when its pKa is 6.1, while the pH of the blood is 7.4? Why do redox reactions occur? Why does NaCl dissolve in water? Why are exothermic reactions useful?
Why are methane and air used in a lime kiln? Why is explosion of fireworks a chemical change? Why does carbon dioxide not obey Charles's law? Why is air combusted in a rocket engine? Why are combustion reactions of fossil fuels so exothermic?
Given that formation of a bond between two atoms is exothermic and accompanied by an entropy decrease, explain why all chemical compounds decompose into individual atoms if heated to a high enough tem A chemical reaction is mo...
If the electronegativity values between two atoms are comparable, they may still form chemical bonds to increase the stability of theirvalence electronshell. These atoms usually form covalent bonds. You can look up electronegativity values for each atom to compare them and decide whether an atom wil...
Fire is hot because thermal energy (heat) is released when chemical bonds are broken and formed during acombustionreaction. Combustion turns fuel and oxygen into carbon dioxide and water.Energy isrequired to start the reaction, breaking bonds in the fuel and between oxygenatoms, but much more en...
