Answer:
156.4g K
Explanation:
I'm not sure if it is correct but I think it should be this
What do we know so far?: 2K + 1Cl2 -> 2KCl, 2 mol of Cl2
What are we looking for?: #g of K
What is the ratio of K to Cl2?: 2:1
Set up equation: 2molCl2 x 
Cancel unwanted units: 2 x 
Answer we got: 2 x 2mol K = 4mol K
Converting moles to grams: 4 x 39.1 (molar mass of K) = 156.4g K
Substances that exist in solution almost completely as ions are called strong electrolytes. Therefore, the answer is C.
1 mole is 6.02x 10^23 molecules
3 * 6.02*10^23 =1.806*10^24 molecules
Answer:
The elements in the periodic table are arranged in order of increasing atomic number.
