1) Chemical formulas can be written as empirical formulas, molecular formulas, or structural formulas. Explain why these different forms of molecular expression are necessary. Chemical formula of a compound can be explained by the following forms - An Empirical formula gives the simplest, whole-number ratio of atoms in a compound. A Molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A Structural formula indicates the bonding arrangement of the atoms in the molecule. 1) Chemical formulas can be written as empirical formulas, molecular formulas, or structural formulas.

1. An instructor gave you direction to construct a model of CH3CH2Br molecule by following the Experimental Procedure section of your     experiment. First you will need to find the number of valence electrons in  CH3CH2Br. The number of valence electrons in an atom of     an element is said to be equal to the last digit in the group number of that element in the Periodic Table. Thus, what Groups are C, H, and Br in? 2.An instructor gave you direction to construct a model of CH3CH2Br molecule by following the Experimental Procedure section  of your experiment. First you will need to find the number of valence electrons in  CH3CH2Br. The number of valence electrons in an atom of an element is said to be equal to the last digit in the group number of that element in the Periodic Table.      The model consisted of balls and sticks.  A ball has holes in it that represent how many bonds an atom can form.   What kind of ball do you think should you use for the C atom and H atom? 3.An…
