Explanation / Answer

Q1.

From your list;

zinc will reac tiwth HCl to form Zn2+ ions, or ZnCl2(aq)

Q2.

complete balance

Zn(s) + 2HCl(aq) --> H2(g) + ZnCl2(aq)

Q3.

6M > 1M so

expect more bubble formation as it is concentrated

Rate of time --> should be proportional

since it is mos tlikely 1st order, then

Rate 6M = k*[HCl] --> 6x than Rate 1M

the reaction gets faster --> for that of 6M

which states that the rate is directly proportional to the concentration of HCl

Surface area:

The powdered Zn has higher surface area, than the sheet of Zn

therefore,

expect more bubbles in th epowder.

The rate of reaction will be faster, therefore

Use powdered zinc + Concentrated acid
