There are several different models that represent compounds. One type of model is shown. 3 C's connected in a line by 2 black lines. The first and third C's each have 3 H's connected to them by a single black line each. The middle C has 2 H's connected to it by a single black line each. What type of model is shown? a structural formula a chemical formula a space-filling model a ball-and-stick model

Answer:
There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of dimethyl ether, a useful organic solvent, is prepared in two steps. in the first step, carbon dioxide and hydrogen react to form methanol and water: (g) (g) (l) (l) in the second step, methanol reacts to form dimethyl ether and water: (l) (g) (l) calculate the net change in enthalpy for the formation of one mole of dimethyl ether from carbon dioxide and hydrogen from these reactions. round your answer to the nearest .f several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: (s) (g) (g) (s) in the second step, acetylene, carbon dioxide and water react to form acrylic acid: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest .
