IV. CH2OH-CH2-CH3

V. CHOO-CH3

VI. CH3-COOH

46. Ethanol

47. Propyl ethanoate

48. Propan 1-Ol

49. Propanoic acid

50. Ethanoic acid

51. Methyl methanoate

Question related to above)

For each of the waters provided, identify the alcohol and the carboxylic acid that reacted

52. Methyl propanoate (-)+ (-)

53. Ethyl methanoate(-) +(-)

Here's what I get  

Explanation:

1. Names

I.   CH₃-CH₂-COOH              = 49. propanoic acid

II.  CH₃-CH₂-OH                    = 46. ethanol

III. CH₃-COO-CH₂-CH₂-CH₃ = 47. propyl ethanoate

IV. H-O-CH₂-CH₂-CH₃         = 48. propan-1-ol

V.  H-COO-CH₃                    = 51. methyl methanoate

VI. CH₃-COOH                      = 50. ethanoic acid

2. Precursors

52. methyl propionate  ⇒ methanol + propanoic acid

53.   ethyl methanoate ⇒    ethanol + methanoic acid

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
