Explanation:

Carbocation Carbanion 1. The central carbon atom is +vely charged. 1. The central carbon atom is -vely charged. 2. It is an electron deficient species. 2. It is an electron rich species. 3. The central carbon atom possesses six electrons in its outermost shell. 3. The central carbon atom possesses eight electrons in its outermost

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
