The enthalpy of formation has a negative sign, which means that the reaction is exothermic. In other words, when ethanol is formed, heat is released to the surroundings as a by-product. The reaction for the formation of ethanol is written below:
<em>C₂H₄ + H₂O → C₂H₅OH</em>
Answer:
Answer is B
Hope I helped
If you are in TCAH use the study guide for the answers!!!
F = MA A = change in velocity Constant velocity = no change in velocity = Zero acceleration Ignoring friction, 5 kg * 0 m/s^2 = 0 N Therefore, there is no force (0 N) required to keep the object in motion if the surface friction is ignored.
I hope my answer has come to your help.
