For the following procedure, write a balanced chemical equation for each reaction. Make sure you include the state of matter (s,aq,g,l) and the type of reaction (decomposition, synthesis, single displacement, double displacement, combustion).

Reaction 1
a. Dip one end of a Q-tip in CONCENTRATED hydrochloric acid.
b. Dip one end of a second Q-tip in CONCENTRAED ammonium hydroxide solution.
c. Record initial observations. Caution: Do not observe reaction close to your eyes.
d. Bring the Q-tips close to one another BUT do not let them touch.
e. After you record your observations, flush with water, wrap in a paper towel, and throw in the trash can.

Reaction 2
a. Place a small piece of potato to a small beaker. PLEASE DO NOT WRITE “POTATO” AS A
REACTANT! There is an enzyme in the potato that acts as a catalyst – do research at home to
determine what this enzyme is!
b. Cover the potato with 3% hydrogen peroxide in the beaker.
c. Clean up your station – decant the solution and throw solid contents of beaker into garbage can,
rinse the beaker. Be sure lab table is clean.

Reaction 1
a. Dip one end of a Q-tip in CONCENTRATED hydrochloric acid.

b. Dip one end of a second Q-tip in CONCENTRAED ammonium hydroxide solution.

c. Record initial observations. Caution: Do not observe reaction close to your eyes.

When one end of a Q-tip is dipped into concentrated hydrochloric acid : producing hydrogen chloride gas.

HCl (aq) ==> HCl (g)
while a second one is dipped into concentrated aqueous ammonia : producing ammonia gas.

NH₃(aq) ==> NH₃(g)

d. Bring the Q-tips close to one another BUT do not let them touch.
e. After you record your observations, flush with water, wrap in a paper towel, and throw in the trash can.

HCl (g) + NH₃(g) ==> NH₄Cl (s) : Synthesis reaction.

b. Cover the potato with 3% hydrogen peroxide in the beaker

Potato contains catalase enzyme.
.
This enzyme catalase work to perform decomposition of peroxide (H₂O₂) .

2 H₂O₂ (aq) ===> 2 H₂O (l) + O₂ (g) : Decomposition reaction.
