This rock is balanced by roots on the ground that are very strong
Answer:
Percent yield = 90.5%
Explanation:
Given data:
Mass of carbon dioxide = 500 g
Mass of water = excess
Actual yield of carbonic acid = 640 g
Percent yield = ?
Solution:
Balanced chemical equation:
CO₂ + H₂O → H₂CO₃
Number of moles of carbon dioxide
Number of moles = Mass / molar mass
Number of moles = 500 g/ 44 g/mol
Number of moles = 11.4 mol
Now we will compare the moles of H₂CO₃ with CO₂.
CO₂ : H₂CO₃
1 : 1
11.4 : 11.4
Mass of carbonic acid:
Mass = number of moles × molar mass
Mass = 11.4 mol × 62.03 g/mol
Mass = 707.14 g
Percent yield:
Percent yield = actual yield / theoretical yield × 100
Percent yield = 640 g/ 707.14 g × 100
Percent yield = 90.5%
<span>In the sentence "The first animal cloned by nuclear transfer was a _____ named Dolly", the word that correctly completes the sentence is sheep. A sheep named Dolly is the first animal cloned from an adult somatic cell by nuclear transfer. She was cloned at the Roslin Institute of the University of Edinburgh, Scotland, in 1996. There she died in 2003.</span>
