Is lightning exothermic or endothermic? How is all this related to a zero-order reaction?
Lighting is a exothermic reaction ,
For example a match box stick - at burn less energy absorbed from surrounding environment and more energy release ,so its exothermic reaction
Is lightning exothermic or endothermic? How is all this related to a zero-order reaction?
Is the following reaction endothermic or exothermic?
please help will greatly appreciate
Is the following reaction endothermic or exothermic ? CH4 (g) + O2 (g) + CO2(g) + H20 (g) + energy endothermic, energy is given off by the reaction AH = (+) value exothermic, energy is absorbed by the reaction exothermic, energy is given off by the reaction endothermic, energy is absorbed by the reaction
Which of the following is true regarding endothermic and exothermic reactions? a reaction which releases energy is exothermic areaction which absorbs energy is endothermic in an exothermic reaction, heat is released in an endothermic reaction, heat is absorbed all of the above are true Oonly a andc are true only b and d are true
