To get the average of your answer
Chemical properties can only be analyzed by putting the substance through a chemical reaction, such as combustion.
Physical properties can be analyzed without altering the substance chemically. With that in mind:
Boiling point: physical
Density: physical
Ductility: physical
Heat of combustion: chemical
I gotchuuuuu it’s Isotopes
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.
<u>Switch the 3 and the 4</u>, this change must made to the coefficients to balance this equation.
Now, the correct balance equation is C₃H₈ + 5 O₂ → 3 CO₂ + 4H₂O
This method of balancing chemical equations involves assigning algebraic variables as stoichiometric coefficients to each species in the unbalanced chemical equation.
