Answer:
ethane=c2h6
ethyne=c2h2
ethene=c2h6
Explanation:
ethane has single bond between carbon atoms(it is alkane.) ethyne has triple bond between carbon atoms(it is alkyne) ethene has double bond between carbon atoms (it is alkene)
The percent yield of indigo : 79.6%
<h3>Further explanation</h3>
Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
2C₁₀H₁₁NO₄ + 2H₂O → C₁₆H₁₀N₂O₂ + 2C₂H₄O₂ + 4H₂O
Actual yield = 1.87 g
Theoretical yield = 2.35 g
The percent yield of indigo :
According to Balance chemical equation,
N₂ + 3 H₂ → 2 NH₃
1 mole of Nitrogen reacts with 3 moles of Hydrogen to produce 2 mole of Ammonia.
It is known that i mole of any gas at standard temperature and pressure occupies 22.4 L of Volume. So, we can also say,
22.4 L (1 × 22.4) of Nitrogen gas (in question it is taken in excess) reacts with 67.2 L (22.4 × 3) of Hydrogen gas to produce 44.8 L (22.4 × 2) of Ammonia.
Result:
44.8 L is the correct answer.
The answer is 1.48 x 10^8. This is because 148 million is represented as 148 000 000 and it takes 8 decimal places to make it 1.48. Hope this helps!
