Answer:
The percentage yield is 80.36% (see calculations in attachment).
Explanation:
The theoretical yield of the reaction is the <u>amount of product that would result if all the limiting reagent reacted.</u> The theoretical yield is calculated using the balanced equation.
In practice, the actual yield, or the <u>amount of product actually obtained from a reaction</u>, is almost always less than the theoretical yield.
To determine how efficient this reaction is, we need to calculate the percent yield, which describes the <u>proportion of the actual yield to the theoretical yield.</u> It is calculated as follows:

First we need to make sure that the equation is properly balanced. In the question they provide the balanced equation.
Since water is in excess, we calculate the theoretical yield using PCl₃.
Answer:
quartz and olivine
Explanation:
According to my research on studies made by different geologists on Bowen's reaction series, it is known that crystal settling should result in the magma being separated in lower layers rich in the early-formed quartz and olivine minerals.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
A is the answer. Chemical changes happen when atomic bonds are broken or created during chemical reactions. Hence, in this case, it involve changes to molecular structure.
- Change in states are physical changes.
- When salts are dissolved in water, you can use Distillation to separate them. Distillation is a physical change as well.
- Dissolving is just physical change.
