Pls help! I'll give brainliest! 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?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? a. the balloons both rise. the cold balloon is larger than the warm balloon. b. the balloons rise at the same rate. both balloons are the same size. c. the warm balloon expands and rises. the cold balloon shrinks and sinks. d. the cold balloon expands and rises. the warm balloon shrinks and sinks.

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3
