Group 1 metals all have one outer electron, which is responisble for their properties. As you go down the group:
Write the equation and balance it. CH4 + 2O2 --> CO2 + 2H2O Assign the enthalpies of formation and the sign of the energy value with the corresponding molecule (Will demonstrate my technique if needed)...
Ethane is a symmetric molecule, therefore both groups of hydrogens occur in the same region and not in two different regions (for example chloroethane would have two different regions). Using the n+1 rule...
Sigma bonds form as a result of end on overlap of orbitals (pp, ss or sp) along the axis between two atoms' nuclei. Pi bonds form because of parallel overlap between p orbitals. A sigma bond forms a singl...
With the first electron affinity, the chlorine atom is one electron from a full octet ( and is a neutral species). When you add an electron to the chlorine, the negatively charged electron is electrostati...
