Answer:
111.15 g are required to prepare 500 ml of a 3 M solution
Explanation:
In a 3 M solution of Ca(OH)₂ there are 3 moles of Ca(OH)₂ per liter solution. In 500 ml of this solution, there will be (3 mol/2) 1.5 mol Ca(OH)₂.
Since 1 mol of Ca(OH)₂ has a mass of 74.1 g, 1.5 mol will have a mass of
(1.5 mol Ca(OH)₂ *(74.1 g / 1 mol)) 111.15 g. This mass of Ca(OH)₂ is required to prepare the 500 ml 3 M solution.
First off, you should be looking at the whole world, not just the northeastern US. Are other regions warming? Can you provide proof that simply because the northeast received a lot of snow and low temperatures, climate change is not a viable theory?

Sodium chloride as we know is table salt which we usually used in our food as condiments. However, the individual components that makes them are highly dangerous. Sodium is a very reactive metal that upon contact with water or air, they become explosive. Chlorine, a gas, is very poisonous and was one of the most lethal weapons used during ww2. But when they are formed to become sodium chloride, the properties have completely changed and hence are different from sodium and chlorine properties.
