(Yield Problem)
alex41 [277]

Answer:

Percent Yield Fe  =  82.5%

Explanation:

The actual yield is the value produced after an experiment is conducted. The theoretical yield is the value calculated using the balanced chemical equation and atomic/molar masses.

To find the percent yield of iron (Fe), you need to (1) convert grams Al to moles Al (via atomic mass), then (2) convert moles Al to moles Fe (via mole-to-mole ratio from equation coefficients), then (3) convert moles Fe to grams Fe (via atomic mass), and then (4) calculate the percent yield. It is important to arrange the ratios in a way that allows for the cancellation of units. The final answer should have 3 sig figs to reflect the sig figs of the given values.

Atomic Mass (Mg): 24.305 g/mol

Atomic Mass (Fe): 55.845 g/mol

3 Mg + 2 FeCl₃ -----> 2 Fe + 3 MgCl₂

20.5 g Mg           1 mole              2 moles Fe            55.845 g
-----------------  x  -----------------  x  ----------------------  x  -----------------  =  
                           24.305 g           3 moles Mg             1 mole

=  31.4 g Fe

                                     Actual Yield
Percent Yield  =  ----------------------------------  x  100%
                                 Theoretical Yield

                               25.9 g Fe
Percent Yield  =  --------------------  x  100%
                               31.4 g Fe

Percent Yield  =  82.5%

A. what is the hybridization of the central atom in cse2?
elixir [45]

The orbital hybridization of the central carbon atom in CSe2 is sp.

In chemical bonding, atomic orbitals may be combined to form appropriate hybrid orbitals suitable for bonding. The orbitals that combine during hybridization must be close enough in energy.

In the compound Cse2, carbon is the central atom bonded to two selenium atoms. The carbon atom in CSe2 is sp hybridized.

1)Which of the following changes would decrease the rate at which a solid solute dissolves in a liquid solvent? (3 points)
Diano4ka-milaya [45]

Answer:

The first one is B, "Decreasing surface area."

Explanation:

This is because greater the surface area exposed, the more collisions that occur between the solvent and solute. I also just took the test myself and got it correct.

At the end of the last lesson, you learned there was not enough carbon dioxide in the biodome air, which led to a decrease in en
lakkis [162]

There may be too many plants present or too few animals in the biodome hence the decrease in carbon dioxide .

<h3>What is a biodome?</h3>

The term biodome refers to an artificially buit ecosystem. We must recall that an ecosystem is a self sustaining unit in which materials and energy are exchanged.

If there is less carbon dioxide in the biodome then it means that there are too many plants present or too few animals in the biodome.
