You just look at what vertical row that silicon is, and every element that is in the same vertical row as silicon will have the same lewis dot structure...and this applyes for most elements on the periodic table of elements.
- C, Ge,Sn, Pb:
all these elements are in the same column, and therefore have the same number of valence electrons
Answer:
1. more slowly than
2. larger than
3. weaker
Explanation:
Acetone molecules are bonded by very weak intermolecular forces when compared to that of the hydrogen bond between water molecules. This makes it very easy for acetone molecules to vaporize easily into its gaseous state, much more faster than water molecules (since the acetone molecules need a lesser amount of energy to break these bonds). Also, the boiling point of liquid acetone is much lower than that of water, meaning that it has a higher vapor pressure than that of water.

I believe this would be an exothermic reaction, As time increases, the temperature goes up meaning the heat from the system is going into the surroundings. Which indicates an exothermic reaction.
