8.) If 396 g of Carbon Dioxide (CO2) are produced, what mass of Oxygen

Chemistry
1 answer:
KengaRu [80]3 years ago
3 0

Answer:

480 g of oxygen.

Explanation:

C3H8 + 5O2 --->  3CO2 + 4H2O

Using the molar masses:

3*12 + 6*16 g of CO2 were formed from 10*16 g O2

132g  g CO2 from 160 g O2

1g CO2 from (160/132) g O2

396 g from (160/132) * 396

= 480 g of oxygen.

A. Explain, in terms of particles, why NaCl(s) does not conduct electricity.
yawa3891 [41]

Answer:

Ionic bonds hold charged particles in solid NaCl together, such that they are unable to move or conduct electricity.

Explanation:

Consider an electric current that flows through a conductor: charge moves in a uniform direction from one end of the conductor towards the other.

Thus, there are two conditions for a substance to conduct electricity:

  • The substance shall contain charged particles, and
  • These charged particles shall be free to move across the substance.

A conductor of electricity shall meet both requirements.

Now, consider the structure of solid NaCl \rm NaCl\;(s). NaCl is an ionic compound. It contains an ocean of oppositely charged ions:

  • Positive \rm Na^{+} ions, and
  • Negative \rm Cl^{-} ions.

Ions carry charge. Thus, solid NaCl contains charged particles and satisfies the first condition.

Inside solid NaCl \rm NaCl\;(s), electrostatic attractions ("ionic bonds") between the oppositely charged ions hold these ions in rigid ionic lattices. These ions are unable to move relative to each other. As a result, they cannot flow through the solid to conduct electricity. Under solid state, NaCl is unable to satisfy the second condition.

As a side note, melting NaCl into a liquid breaks the ionic bonds and free the ions from the lattice. Liquid NaCl is a conductor of electricity.

How do isotopes of an atom differ? how are they the same?
otez555 [7]

Answer: Isotopes of an atom are different because they have different atomic masses and different number of neutrons within their nucleus. They are the same since they will always have the same atomic number/number of protons in their nucleus.
