HELP FAST + explain PLZ! The combustion of propane, CH3CH2CH3, proceeds according to the following chemical reaction: CH3CH2CH3 + 5O2 → 3CO2 +4H2O. What are the parent shapes of the two product molecules? The order does not matter. A) linear and octahedral

B) trigonal pyramidal and linear

C) trigonal pyramidal and tetrahedral

D) bent and tetrahedral

E) tetrahedral and linear

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
