ΔΗ, ΔΗ, AHxn V Which of the following statements is true? The overall chemical reaction is exothermic. o There are two intermediate reactions in this system. The third intermediate reaction is endothermic. O The longest arrow represents the overall chemical reaction. Mail this and return GILBERT

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

May someone me with these science questions

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.
