Answer: it is c

Explanation:

Islands can also be formed when continental plates collide. When they collide they push land up creating an underwater mountain that goes above land. This land, when surrounded by water, is called an island. Another way an island land form can be made is through deposits of sand that came from erosion. have a great day! :3

andriy [413]

Answer:

It would take 12 hours.

Explanation:

It takes 24 hours to move from point A back to it's position. So if it goes half way you divide by two and you get 12. So it would be B.

If a chemical reaction such as photosynthesis begins with 6 atoms of carbon C , how many atoms of carbon C should be in the prod
pochemuha
B. 6 atoms of carbon C
I would think this is the answer, because one can't just delete or add atoms; otherwise, the equation would be unbalanced. This also abides with the Law of Conservation of Mass.

Plus, I also came to that conclusion because if we look at the net equation of photosynthesis:
6C O_{2} + 6H_{2}O ––> C_{6}H_{12}O_{6} + 6O_{2}
The number of Carbon atoms is 6 on both the reagent's side and the product's side.

The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0 % yield. How many grams would be pro
zepelin [54]

7.66g of ethyl butyrate is produced.

The reaction is

CH₃CH₂CH₂COOH + CH₃CH₂OH ----> CH₃CH₂CH₂COOCH₂CH₃

  • The molar mass of butanoic acid is 88.11g/mol
  • We have 7.45g of butanoic acid
  • The moles of butanoic acid we have is 7.45/88.11 = 0.0845 mol
  • If the yield is 100%,  1 mole of butanoic acid gives 1 mole of ethyl butyrate
  • But the reaction yield is 78%
  • 1 mole of butanoic acid gives 0.78 mole of ethyl butyrate

From 0.0845 mol of butanoic acid we get 0.78 x 0.0845 = 0.66 mol of ethyl butyrate.

The molar mass of ethyl butyrate is 116.16g/mol

So 0.66 x 116.16 = 7.66g

7.66g of ethyl butyrate is produced.
