In [Cu(NH 3 ) 4 ] 2+ , the subscript 4 indicates which of the following?

Hey everyone welcome back. So let's get started with this video. So who they want us to identify? Which statement is not true. Okay, so let's read a a formula unit is the empirical formula of any ionic or Covalin network solid compound. Okay, so then a formula unit represents the smallest whole number ratios that exists between ions. Which is literally what an empirical formula is. Two. So then this one is going to be true. Let's look at me, structural formulas, identify the location of chemicals, chemical bonds between the atoms of a molecule. Okay, so then structural formulas, they will give us the arrangement of atoms in a molecule. Then they will identify the location chemical bonds between the items. So then B is true. It's a cat C. The stereo chemical formula shows the orientation of the bonds and non bonded valence electrons. Okay, so then stereo chemical formula, this is basically a three D representation of a molecule as it has wedges and dotted lines and they will show the orientation but they do not show valence electrons because valence electrons, that is basically a lewis structure. So because Finance electrons are for lewis structure and the stereo chemical formula will not show this. This is what this one is going to be false because stereo chemical formulas do not show valence electrons. Okay, let's get D The empirical formula of a compound is the simplest whole number ratio. Adams President of compound. Once again, yes because it's the smallest whole number ratio. So D is true. And then the molecular formula uses chemical symbols to indicate that types of atoms, followed by sub scripts to show the number of atoms in each type of molecule. So this one is true because it's literally the formula of a molecule. So it's telling you what it's composed of. So this one is true. So then the only one that is not true is going to be C. Because stereo chemical formulas do not show valence electrons. Okay, Thank you for watching. I hope this helped. And I'll see you in the next video.
