IPC Unit 4 Practice Test questions well
answered graded A+
H2 + S + O2 - correct answer ✔✔Choose the correct answer based on the reaction.
What are the products?
H2SO4(aq) --> H2(aq) + S(s) + O2(aq)
Covalent - correct answer ✔✔A bond formed when two atoms share their valence electrons to
form a compound is a(n) ________________________ bond.
Blowing on a fire increases the concentration of oxygen and increases the reaction rate. -
correct answer ✔✔Burning wood is a chemical reaction that requires oxygen. Sometimes
people start a fire by lighting paper with a match and then blowing gently on the lit paper.
Blowing on the lit paper helps the reaction rate, or fire, go faster. Blowing on the lit paper
moves more air, which contains oxygen, over the reaction site.
Which statement is true about why this works?
Synthesis - correct answer ✔✔Choose the correct reaction type for the following.
1O2 + 1H2 --> 2H2O
Beryllium Chloride - correct answer ✔✔Name the compound.
BeCl2
Oxidized - correct answer ✔✔A substance that loses electrons and becomes more positive is

________________________ is neither created nor destroyed during a chemical reaction.
Increasing the Surface Area - correct answer ✔✔Which of these factors increases the rate of a
reaction?
Ionic Bond - correct answer ✔✔Which type of bond will cesium (Cs) and selenium (Se) form?
Ionic - correct answer ✔✔A bond that is formed when there is a force of attraction between the
opposite charges of ions is a(n) ________________________ bond.
