Answer:
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
Explanation:
Answer:
- blue-black PHYSICAL PROPERTY
- crystalline PHYSICAL PROPERTY
- solid PHYSICAL PROPERTY
- sublimes to a violet-colored gas PHYSICAL PROPERTY
- reacts with aluminum and many other metals CHEMICAL PROPERTY
Explanation:
Chemical properties are visible through chemical reactions, in which the chemical identity changes to form new substances. On the other hand, physical properties are evident without a change in the identity of a substance.

<em>Which of these five properties are physical and which are chemical?</em>
- blue-black PHYSICAL PROPERTY
- crystalline PHYSICAL PROPERTY
- solid PHYSICAL PROPERTY
- sublimes to a violet-colored gas PHYSICAL PROPERTY
- reacts with aluminum and many other metals CHEMICAL PROPERTY
Answer:
The calculations is shown in the attached file.
Explanation:
- The concept of dipole moment is applied here. the size of the dipole moment is given by multiplying the size of the charge by the distance apart.
- For simpler molecules, the sizes of the dipole moments are approximately proportional to the difference between the electronegativities of the atoms. Dipole moments are usually measured in debyes (D).
Dipole moments (μ) = q x r
The detailed calculation is shown in the attachment.
Depends if the reaction is endo or exo thermic
Endothermic reaction
Increasing the temperature will shift the equilibrium to the right-hand side of the equilibrium. to oppose the change in temperature.
Exothermic reaction
Increasing the temperature will shift the equilibrium to the left-hand side of the equilibrium. to oppose the change in temperature.
