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:
1) all matter is made up of atoms and molecules 2) these tiny particles are always in motion; the higher the temp. the faster they move 3) at the same temp., heavier particles move more slowly then small particles
Explanation:
Start with Unbalanced Equation and balance it, so...
C7H16+O2--->CO2+H2O
There are 7 C atoms on the left-hand side, so we need 7 C atoms on the right-hand side. Add a 7 in front of the CO2...7CO2+H2O on right side now.
We have fixed 16 H atoms on the left-hand side, so we need 16 H atoms on the right-hand side. Add an 8 in front of H2O to make 16 (8x2)...7CO2+8H2O on right side now.
There are 22 O atoms on the right-hand side: 14 from the CO2 and 8 from the H2O. Add an 11 in front of the O2 on the left side to make 22 (11x2).
Every formula now has a fixed coefficient. You should have a balanced equation of...
C7H16+11O2--->7CO2+8H2O
