Answer: Option (a) is correct.
Explanation:
A person with less skills needs to work more or practice more on his abilities in order to improve their athletic ability to build a stronger team.
Over encouragement to lesser skilled person can lead to the development of over confidence. As after over encouragement, the less skilled person can have the illusion of knowing each and everything which is not true for anyone.
As no one is perfect, therefore, over-encouraging lesser skilled players can lead to embarrassment.
For example,
"Which of the following molecules is expected to have one or more unpaired electrons? Check all that apply.
O2-
F2+
N22-
O22-"
Any help would be appreciated. ...?
To determine unpaired electrons, look at the valence electrons in an ion's molecule, accounting for extra or absent electrons due to the ion's charge. For instance, O2- and F2+ have one unpaired electron, but N22- is not a valid ion, and O22- electrons are all paired.
To determine if a molecular ion will have one or more unpaired electrons, we need to look at the number of valence electrons in the molecule and take into account any extra or absent electrons due to the charge of the ion.
For example, O2- has 12 + 1 = 13 valence electrons (6 from each oxygen atom and 1 extra due to the negative charge). It requires 14 for all the electrons to be paired (2 in each oxygen's inner shell and 4 bonds or lone pairs in the outer shell), thus there is one unpaired electron in O2-.
However, in F2+, there are only 13 electrons because one electron is lost due to the positive charge. Like oxygen, fluorine also prefers to have 7 electrons in its outer shell, so there are also unpaired electrons in F2+.
N22- doesn’t exist because nitrogen normally forms triple bond and doesn’t need or want to take extra electrons, so this molecular ion is not valid.
O22- has 14 + 2 = 16 valence electrons and this total number of valence electrons is an even number, which indicates all the electrons are paired.

b. the absorption of energy.
c. no energy change.
Answer:
The correct answer is option a. the removal of energy.
Explanation:
Hello!
Let's solve this!
Freezing is a process by which a lot of heat is lost, this loss of heat leads to a loss of energy as well. It means that energy is eliminated so that heat loss occurs.
Therefore the correct answer is option a. the removal of energy.
Answer:
False
Explanation:
Rainforests are very important for global oxygen movement, but they are not the main element for oxygen movement.
Seaweed is the real lung of the world, it is primarily responsible for the global movement of oxygen as it produces more oxygen through photosynthesis than it needs in breathing, and the excess is released into the environment. Rainforests release much less oxygen into the atmosphere worldwide, as most of the gas produced is consumed in the forests themselves. However, rainforests are extremely important and should not be destroyed.
Calorimeter is used for calculating specific heat capacities of a substance.
We can use the calorimeter in order to compare the specific heat capacities of a substance because calorimeter is a device which is used for measuring the heat produced during a mechanical, electrical or chemical reaction. This device has the ability to calculate the heat capacity of materials.
The heat released from the sample is absorbed by the water, which results in an increase in temperature. This calorimeter detect this increase in temperature and provides us information so we can conclude that calorimeter is used for calculating specific heat capacities of a substance.
