A chemist performs the synthesis of sodium chloride from its
2016年4月16日 · We have 2 mol of sodium metal to start; clearly we need the 1 mole of Cl_2(g). "Moles of sodium "=(46.0*g)/(22.9*g*mol^-1)=2*mol. Given your equation, clearly we need the ONE mole of Cl_2 gas. What is the mass of this quantity of chlorine? It is fact that all of the elemental gases EXCEPT for the Noble Gases are diatomic: N_2, O_2, F_2, Cl_2. Of course, …
How many unpaired electrons are in chloroform? | Socratic
2015年8月15日 · There are 18 unpaired electrons in a molecule of chloroform, "CHCl"_3". Each chlorine atom has 7 valence electrons. One of those electrons will bond with the central carbon atom. This will leave a total of six unpaired electrons on each chlorine atom. Therefore, there is a total of 18 unpaired electrons.
How do I calculate the number of chloride ions in a solution?
2017年3月6日 · Here's how you can do that. Your strategy here will be to use the molarity and volume of the solutions to figure out how many moles of salt were dissolved to make the solution. Once you know that, you can use the chemical formula of the salt to figure out how many moles of chloride anions, "Cl"^(-), will be produced in each solution. I'll show you how to solve points A) …
