Lol this is so late but...

1.) Sodium hydroxide because when diluted it creates a precipitate when coming in contact with calcium ions
2.) Chloramine vapors are created
3a.) Scarlet kingsnake
3b.) idk if this is right but the scarlet kingsnake stripes are equally sized while the eastern coral snake has a smaller yellow border around the larger red and black stripes

Mostly right - 3b I was more thinking about the different stripe color patterns (red touch yellow, kill a fellow, red touch black, friend of Jack).
Anyways, your turn!

2. If a salt solutions contains 96% salt, and is a volume of 46mL, how much water would need to be added to make it 43%?
3. What is the most electronegative element on the periodic table?
