Answer:
Charge is caused by a flow of electrons, since electrons are around the nucleus they can be lost or gained by atoms. When an atom gets charged, it gains a charge, that is, it gains an electron. Since electrons are negatively charged, when an atom gains one, it also becomes negatively charged.
Answer:
47.47 g of CO₂ is the amount formed.
Explanation:
The reaction is:
2C₆H₅COOH(aq) + 15O₂(g) → 14CO₂(g) + 6H₂O(l)
Let's apply the formula for the percent yield
Percent yield of reaction = (Produced yield/Theoretical yield) . 100
First of all we convert the moles of CO₂ to mass: 1.30 mol . 44 g /1 mol = 57.2 g. So now, we replace:
(Produced yield / 57.2 g ). 100 = 83
Produced yield / 57.2 g = 83 / 100
Produced yield / 57.2 g = 0.83
Produced yield = 0.83 . 57.2g → 47.47 g of CO₂
Answer:
low-spin complexes contain the maximum number of unpaired electrons.
Explanation:
In the crystal field theory, the magnitude of crystal field splitting and the pairing energy determines whether a complex will be low spin or high spin.
Low spin complexes often have greater magnitude of crystal field splitting energy than low spin complexes.
High spin complexes have maximum number of unpaired electrons(most of the electrons are unpaired) while low spin complexes have a minimum number of unpaired electrons in a complex(most of the electrons are paired).
The answer is 3.10 because it's still the same amount moles of iron.
