3. Suppose you wanted to design an experiment to test the composition of a mixture that includes sodium phenoxide (NaC6H5O). You
Liula [17]

Answer:

21.5mL of a 0.100M HCl are required

Explanation:

The sodium phenoxide reacts with HCl to produce phenol and NaCl in a 1:1 reaction.

To solve this question we need to find the moles of sodium phenoxide. These moles = Moles of HCl required to reach equivalence point and, with the concentration, we can find the needed volume as follows:

<em>Mass NaC6H5O:</em>

1.000g * 25% = 0.250g NaC6H5O

<em>Moles NaC6H5O -116.09g/mol-</em>

0.250g NaC6H5O * (1mol/116.09g) = 2.154x10⁻³ moles = Moles of HCl required

<em>Volume 0.100M HCl:</em>

2.154x10⁻³ moles HCl * (1L/0.100mol) = 0.0215L =

<h3>21.5mL of a 0.100M HCl are required</h3>

When 32.5g of carbon is heated with silicone dioxide, 28.8 g of carbon monoxide is produced. What is the percent yield of carbon
Anvisha [2.4K]

Answer:

Percent yield of carbon monoxide is approximately 38%.

Explanation:

Given reaction : C + SiO₂ → Si + CO

On balancing it : 2C + SiO₂ → Si + 2CO

⇒ 2 mole of carbon produces 2 mole of carbon monoxide

or 2×12=24 g of carbon produces 2×(12+16)=56 g of carbon monoxide

⇒ Expected yield of carbon monoxide when 32.5g of carbon is heated with silicon dioxide is 32.5×\frac{56}{24}

⇒ Expected yield = \frac{455}{6} = 75.8 g

Actual yield is given as 28.8 g

⇒ The percent yield of carbon monoxide = \frac{Actual\ yield}{Expected\ yield}×100

= \frac{28.8}{75.8}×100

≅<u>38%</u>
