Answer:
Y = 62.5%
Explanation:
Hello there!
In this case, for the given chemical reaction whereby carbon dioxide is produced in excess oxygen, it is firstly necessary to calculate the theoretical yield of the former throughout the reacted 10 grams of carbon monoxide:
Finally, given the actual yield of the CO2-product, we can calculate the percent yield as shown below:
Best regards!
Answer:
The answer is
<h2>126.58 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
<h3>
</h3>
From the question
mass of alcohol = 100 g
density = 0.79 g/mL
The volume is
We have the final answer as
<h3>126.58 mL</h3>
Hope this helps you
<span>a.the nearest 1 ml
1 mL is much more precise than 100 mL because 1 mL is a very small and precise unit of measurement</span>
Answer:
1) P₄ + 5O₂ → P₄O₁₀ redox reaction
2) P₄O₁₀ + 6H₂O → 4H₃PO₄ acid-base reaction
3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄ precipitation reaction
Explanation:
The reactions that take place in the <u>electric furnace method</u> are:
1) P₄ + 5O₂ → P₄O₁₀
This is a redox reaction, because the oxidation state of the reactants is changed.
2) P₄O₁₀ + 6H₂O → 4H₃PO₄
This is an acid-base reaction, because there's an exchange of H⁺ species.
The reaction that takes place in the <u>wet process</u> is:
3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄
This is an precipitation reaction, because a precipitate (a solid phase in a liquid phase) is formed.
