You need to list the elements but remember that fluorine has the highest electronegativity out of the entire periodic table
The compound that is formed is: MgI2
Answer:
334.2× 10²³ molecules
Explanation:
Given data:
Mass of water = 1 Kg ( 1000 g )
Number of molecules = ?
Solution:
Number of moles of water:
Number of moles = mass/ molar mass
Number of moles = 1000 g/ 18 g/mol
Number of moles = 55.5 mol
1 mole contain 6.022× 10²³ molecules
55.5 mol×6.022× 10²³ molecules
334.2× 10²³ molecules
Correct answer is:
,,Atoms can react together, be separated from each other, or be rearranged via chemical reactions. "
