Chemistry
1 answer:
klasskru [66]3 years ago

Answer:

A. Theoretical yield = 3.51g

B. %yield = 75%

Explanation:

The balanced equation for the reaction is given below:

C2H4 + 3O2 —> 2CO2 + 2H2O

Molar Mass of O2 = 16 x 2 = 32g/mol

Mass of O2 from the balanced equation = 3 x 32 = 96

Molar Mass of H20 = (2x1) + 16 = 18g/mol

Mass of H2O from the balanced equation = 2 x 18 = 36g

A. From the equation,

96g of O2 produced 36g of H2O

Therefore, 9.35g of O2 will produce = (9.35 x 36)/96 = 3.51g of H2O

Therefore,theoretical yield of water (H2O) = 3.51g

B. Theoretical yield = 3.51

Actual yield = 2.63g

%yield =?

%yield = Actual yield/Theoretical yield x 100

%yield = 2.63/3.51

%yield = 75%

What is the function of the phytoplankton in the ocean ecosystem
Nitella [24]

Phytoplankton is a type of micro algae. This creature is similar to the other plants in the ocean biome. But what makes it special is the fact that it is the main produce in the food web. The plant is so small that it is impossible to see it with the naked eye.
