Write a chemical formula for each molecular model. (See Appendix IIA for color codes.)
Hey guys, so in this question we're trying to write the chemical formula based on the drawing that they provided, now the rule is that if it's shaded in the color black it represents the carbon atom, if it's shaded in the color gray it represents the hydrogen atom, so now that we know what color represents which atom the next step is to count the number of the shaded atoms, let's focus on the Carbon, how many atoms are shaded in the color black? Just one, which is in the center right over here so that means you only have 1 carbon atom, OK? Next how many are shaded in the color grey? We have 1 2 3 4, so that means we have 4 hydrogen atoms, the way we write that is going to put hydrogen and number 4 at the bottom, OK? The reason we don't put 1 with the Carbon is because the 1 is imaginary, OK? So you never write it it's just known that it's there so the formula for this is going to be CH4 so once again the color black represents the carbon atoms and the color grey represents the hydrogen atom, OK? See you guys soon.
