Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions Example : C(g)+O(2)(g)rarr CO(2)+ Heat Energy Reactions that absorb energy or require energy in order to proceed are called endothermic reacti
A chemical reaction where the energy required for bond breakage is less than the energy required for bond formation, resulting in release of energy during the reaction is known as an exothermic reaction. e.g. : CaO+H(2)OtoCa(OH)(2)+"energy". A chemic
Do catabolic pathways release energy? What is the purpose of stage 3 catabolic pathway? What is the major catabolic reaction in biomolecules? What are the three catabolic pathways? What is the biological definition of energy? What phase is catabolic anabolism?
Where does the energy come from that is needed for an endothermic reaction? Is hairspray a liquid or gas? 2.98 g of a gas (20.6 g mol^{-1}) was dissolved in liquid water in a calorimeter with a calorimeter constant of What are some physical changes that are p...
How is the rate of reaction measured for an enzyme? Why is water used in heating systems to warm houses in cold climate? Why do reactants become hotter during exothermic reactions when they are losing energy and why do reactants become colder when they are gaining energy in endothermic reac...
Is the phase change of gas to liquid endothermic or exothermic? Explain. Which of these physical changes would require energy from the surroundings? a. Cooling down hot water to room temperature. b. Freezing a liquid to solid. c....
Explain how a chemical reaction can either release energy or store energy. Why does the electronegativity decrease from top to bottom as a trend in the periodic table? Why is the plasma membrane so important to operation of cells? Is a single molecule of oxygen ( O_2 ) held together...
An increase in temperature will affect vapor pressure by: (a) decreasing the density of the gas molecules, making them lighter and easier to move around (b) increasing the average kinetic energy of the molecules, making them move faster and collide more ( Hydrocarbons rele...
