Answer:
the % yield is 82%
Explanation:
Given the data in the question,
we know that;
Molar mass of benzil is 210.23 g·mol−1
Molar mass of dibenzyl ketone is 210.27 g·mol−1
Molar mass of tetraphenylcyclopentadienone is 384.5 g·mol−1
Now,
2.0 g benzil = 2 g / 210.23 g·mol−1 = 0.0095 mole
2.2 g dibenzyl ketone = 2.2 / 210.27 = 0.0105 mole
3.0 g of tetraphenylcyclopentadienone = 3 / 384.5 = 0.0078 mole
Now, the limiting reagent is benzil. 0.0095 mole can reacts wiyh 0.0095 mole of dibenzyl ketone
percentage yield = ( 0.0078 mole / 0.0095 mole ) × 100%
= 0.82 × 100%
= 82%
Therefore, the % yield is 82%
There are questions about the external validity of the results because single-subject experiments frequently only involve a small number of subjects.
<h3>What is experimentation with a single subject?</h3>
A type of quantitative research known as single-subject studies includes closely examining each participant's behavior in a small sample size. It should be noted that the phrase "single-subject" does not necessarily suggest that only one participant is being examined; rather, it usually refers to a group of two to ten.
<h3>What does a single-subject research design aim to achieve?</h3>
Single subject research design is a sort of research methodology that involves monitoring a single phenomena repeatedly over time (often a behavior), and it is typically used to test interventions.
<h3>What features distinguish single-subject studies?</h3>
Changes on the DV can be measured using data gathered before, during, and after the intervention.

Answer:
54 electrons
Explanation:
I(iodine) has 7 electrons on the last level, so it can take 1 more electrons.
I- also shows that 1 additional electron was added. (I^-1)
I (iodine) has 53 electrons.
So, I- will have 54 electrons.
<span>Contrails are clouds formed when water vapor condenses and freezes around small particles (aerosols) that exist in aircraft exhaust. Some of that water vapor comes from the air around the plane; and, some is added by the exhaust of the aircraft.</span>Aug 5, 2016
Answer:
10 molecular orbitals
Explanation:
The number of atomic orbitals combined to form a molecule is the same number if molecular orbitals that will be found in the molecule. Hence, the number of orbitals are conserved. Some of these orbitals will be bonding molecular orbitals while others will be anti bonding molecular orbitals.
