The table shows the thermodynamic data for a reaction. Thermodynamic Data Energy of the Reactants Energy of the Products Activat
ion Energy 160 kJ 370 kJ 260 kJ Which of the following statements explains if the reaction is endothermic or exothermic? The activation energy is lower than the change in enthalpy, so it is an exothermic reaction. The activation energy is higher than the change in enthalpy, so it is an endothermic reaction. The change in enthalpy is −210 kJ, so it is an exothermic reaction. The change in enthalpy is +210 kJ, so it is an endothermic reaction.
Bed frame is metal so it is able to be sturdy and hold up cleaning agents are mettaliods some contain boron to control strength of bleach , and removing stains plotting soil is non metal it is rich with nitrogen which is good for plants
