Formaldehyde is an organic compound. Each molecule includes two hydrogen (H) atoms, one oxygen (O) atom, and one carbon (C) atom. Below are the dot structures for each of these elements. At left, a purple circle labeled H surrounded by two concentric circles, the inner with nothing on it, the outer with 1 small green spheres. In center, a purple circle labeled O surrounded by two concentric circles, the inner with 2 small green spheres, the outer with 6 small green spheres. At right, a purple circle labeled C surrounded by two concentric circles, the inner with 2 small green spheres, the outer with 4 small green spheres.
Which diagram shows how the covalent bonds most likely form in a formaldehyde molecule?

C connected above and below to H's by 1 line each. C also connected by two lines to O, which has 2 dots each above and below.

C connected above and below to H's by 1 line each. C also connected by three lines to O, which has 2 dots each above and below.

O connected above and below to H's by 1 line each. O also connected by two lines to C, which has 2 dots above.

O connected above and below to H's by 1 line each. O also connected by two lines to C, which has 2 dots each above and below.

Actual ingredients of lab (the cookies i am actually making) 1/2 cup sugar 1/2 cup brown sugar 1 1/3 stick margarine 1 egg 1/2 tsp salt 1 tsp vanilla 1/2 tsp baking soda 1 1/2 cup flour 1 1/3 cup chocolate chip can you answer the questions below ? discussion 1. suppose you are given the following amounts of ingredients: 1 dozen eggs 24 tsp. of vanilla 1 lb. (82 tsp.) of salt 1 lb. (84 tsp.) of baking soda 3 cups of chocolate chips 5 lb. (11 cups) of sugar 2 lb. (4 cups) of brown sugar 1 lb. (4 sticks) of margarine a. for each ingredient, calculate how many cookies could be prepared if all of that ingredient were consumed. (for example, the recipe shows that using 1 egg- with the right amounts of the other ingredients- yields 24 cookies. how many cookies can you make if the recipe is increased proportionately for 12 eggs? ) b. to determine the limiting reactant for the new ingredients list, identify which ingredient will result in the fewest number of cookies. c. what is the maximum number of cookies that can be produced from the new amounts of ingredients?
