Answer:
see explanation
Explanation:
The Lewis structure of a substance is otherwise known as its dot electron structure. It gives an immediate picture of the bonding and number of electron pairs in the molecule. The diagram shows only the valence electrons on each of the bonding atoms in the molecule and how they combine to form the molecule under consideration.
The correct Lewis structure for CO2 is shown in the image attached. CO2 has 16 valence electrons. This can be verified by counting the number of dots in the image attached.
Answer:
B
Explanation:
Condensation happens when there is a drop in temperature. As the heat decreases, the speed that molecules move also decreases. Furthermore, as a gas turns into a liquid, the molecules become more packed together, making the volume decrease, and the shape to become more defined.
If a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced. Details about number of moles can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated as follows:
The following chemical equation was given as follows:
C3H8 + 502 = 3CO2 + 4H₂O
1 mole of C3H8 produced 3 moles of carbon dioxide
Hence, 3.53 moles of C3H8 will produce 3.53 × 3 = 10.59 moles of CO2.
Therefore, if a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced.

C. It has mass and volume
Explanation:
Every atom of an element has mass and volume. Mass is the amount of substance it contains this is usually a function of their subatomic particles.
The bulk of the mass of an atom is concentrated in the nucleus where we have protons and neutrons. Electrons do not really add much to the mass of an atom.
Atoms also have specific volume.
- The reason for our selection is that atoms are the smallest particle of matter.
- Matter is anything that has weight and occupies space.
- Since it is matter, it must have specific weight and volume
