1. When you are underwater, sounds that you hear from above the water sound much quieter than when you are not underwater. Draw a diagram of the reflection and transmission of sound waves that shows why this might be the case.

Explanation:

the water make it sound different then above water

hop this helps

CO + 2 H2 → CH3OH 
 find # of mols in each reactants, 

152500 g CO x 1 mol CO / 28.01g CO = 5444 mol CO 

24500 g H2 x 1 mol H2 / 2.02 g H2 = 12129 mol H2 

mol ratio between CO and H2 is 1:2, which means each mol of production of CH3OH need 1 mol of CO and 2 mol of H. 

H2 is enough to produce 6064 mols of CH3OH but there are only 5444mol of CO. 

5444 mol CH3OH x molar mass of CH3OH / 1 mol CH3OH 

= 174371 g = 174.4 kg
