Answer:
Radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold the nucleus together due to an excess of either protons or neutrons.
Hope this helps!
Answer:
The correct option is: protons; electrons
Explanation:
The electron transport chain contains a series of biomolecules that are involved in the transfer of electrons by redox reactions.
This process involves the transfer of electrons from an <u>electron donor molecule to an electron acceptor molecule</u>, resulting in the <u>release of energy.</u> Some amount of this energy is then used in <u>pumping the protons across the biological membrane.</u>
Answer: Percent yield = 88%
Explanation:
Given data:
Mass of C₇H₆O₃ = 200.0 g
Actual yield of aspirin = 231 g
Percent yield = ?
Solution:
Chemical equation:
C₇H₆O₃ + C₄H₆O₃ → C₉H₈O₄ + C₂H₄O₂
Number of moles of aspirin:
Number of moles = mass/molar mass
Number of moles = 200.0 g/ 138.12 g/mol
Number of moles = 1.45 mol
Now we will compare the moles of aspirin with C₇H₆O₃.
C₇H₆O₃ : C₉H₈O₄
1 : 1
1.45 : 1.45
Theoretical yield of aspirin:
Mass = number of moles × molar mass
Mass = 1.45 g × 180.158 g/mol
Mass = 261.23 g
Percent yield:
Percent yield =( actual yield / theoretical yield )× 100
Percent yield = (231 g/ 261.23 g)× 100
Percent yield = 0.88 × 100
Percent yield = 88%
