A reaction was performed in which 0.55 g of 2‑naphthol was reacted with a slight excess of allyl bromide to make 0.59 g of allyl

2‑naphthyl ether. Calculate the theoretical yield and percent yield for this reaction. Allyl bromide has a density of 1.40 g/mL .

Answer:

  • Theoretical yield = 0.7028 g
  • Percent yield = 83.95%

Explanation:

The reaction that takes places is:

  • C₁₀H₈O + C₃H₅Br → C₁₃H₁₂O + HBr

The<u> theoretical yield</u> is calculated when assuming that <em>all of the limiting reactant transformed into the product</em>:

  • 0.55 g naphthol ÷ 144gNaphthol/mol * \frac{1molAllyl-Naphthyl Ether}{1molNaphthol} * 184 gEther/mol = 0.7028 g

The <u>percent yield</u> is calculated using the theoretical yield and the experimental yield:

  • 0.59g / 0.7028 g * 100% = 83.95%

What is the difference between ionic compund and covalent compound​
sleet_krkn [62]

A covalent bond is formed between two non-metals that have similar electronegativities.

An <em>i</em><em>o</em><em>n</em><em>i</em><em>c</em><em> </em><em>b</em><em>o</em><em>n</em><em>d</em> is formed between a metal and a non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.

The fuel used to power the booster rockets on
Effectus [21]

Answer:

746 moles of H2O are been produced from 373 moles of Al.

Explanation:

For every 3 moles of aluminum, you get 6 moles of H2O (double). Therefore, every 373 moles of Al, you will get double as well, that is 746 m.

Explain how you would convert the moles of a compound to the made (grams) of the same compound<br>​
Oduvanchick [21]

Answer:

see notes below

Explanation:

The mole is the mass of substance containing 1 Avogadro's Number of particles. That is, 1 mole substance = 1 formula weight. For elements, 1 mole weight is equal to the atomic weight expressed as grams. For molecules, 1 mole weight is equal to the molecular weight expressed as grams.

1 mole = 1 formula weight

<u>Moles to Grams and Grams to Moles</u>

Grams => Moles

Given grams, moles = mass given / formula weight

*Ask the question => How many formula weights are there in the given mass? => Results is always moles.

Moles => Grams

Given moles,  grams = moles given X formula weight

*Summary

Grams to Moles => divide by formula weight

Moles to Grams => multiply by formula weight
