Answer: C
Explanation:
Put electron pairs about each atom such that there are 8 electrons around each atom (octet rule), with the exception of H, which is only surrounded by 2 electrons. Sometimes it's necessary to form double and triple bonds. Only C, N, O, P and S (rarely Cl) will form multiple bonds. Draw the Lewis dot structure for CF4.
Answer:
Polar Zones - Coldest Temperature
Temperate Zones - Moderate Temperature
Tropical Zones - Hottest Temperature
Explanation:
The closer you are to the Equator, the hotter it gets, as the sun hits the middle of the Earth the most. At the poles, the sun hits it there the least, so it is the coldest. In between, we would have a mild between hot and cold.
*Remember that the Earth is at a tilt, and that is why we have seasons and why the Equator is so hot and the Poles are so cold.
Most young children already have plenty of energy without the need for coffee to sustain them throughout the day, so at least until they are 12 years old, it's best to avoid giving your kids coffee if possible
Answer: The basicity of the salt anion
Explanation:
All the weak acid is neutralized at the equivalence point and transferred to its conjugate base (number of moles of H+ = increased number of moles of OH–). Therefore the solution produced is weakly alkaline and the pH of the equivalence point will be greater than 7.
