Draw a physical model that shows the reaction of zinc metal and hydrochloric acid (hydrogen chloride). Zinc + Hydrochloric Acid → Zinc Chloride and Hydrogen Gas

Zn + 2HCl → ZnCl2 + H2

Be sure to label your model to clearly show how you are representing the atoms, how they are rearranged and that mass is conserved in the reaction.

I don't need it drawn, if you can just explain to me the reaction and what happens i can draw it. Please?

try answer.com that works for me

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
