See explanation
Explanation:
When left to stand, a solution of Iron II chloride is converted to Iron III chloride by oxidation in air.
The Iron III chloride is composed of weak field ligands in its coordination sphere. These weak field ligands mostly occur in a high spin configuration hence, the central iron atom can be converted from Fe[(H20)6]^2+ .2Cl^-(high spin d6) to Fe^3+[(H20)6]^3+ .3Cl^-(high spin d5).

what kinds of bonds are found in a sample of H2O(s)?
Answer:
a covalent bond? is that what you mean?
Explanation:
If you could show work
We need to balance the equation
[tex]\sf \bullet\quad H_2 + O_2 \longrightarrow H_2O [/tex]
By adding 2 moles of [tex]\sf H_2 [/tex] on the both sides
[tex]\sf \bullet \quad 2H_2+O_2 \xrightarrow{\;By\:balancing\;} H_2O[/tex]
Hence, balanced !
Kelle & Jenn are at a pool. Kelle is standing on the high diving board while Jenn is standing on the low diving board. Assuming the difference in weight/mass is negligible, which of the following statements accurately describes this relationship?
A. Kelle has a greater potential energy than Jenn.
B. Jenn & Kelle have equal potential energies.
C. Jenn has a greater potential energy than Kelle.
D. Kelle has a greater kinetic energy than Jenn.
Answer:
A. Kelle has a greater potential energy than Jenn.
Explanation:
We need to apply the kinetic energy equation here to solve this problem: P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
The problem tells us, however, that mass/weight is negligible; therefore, the only thing that really matters here is the height. Kelle is higher up, so she would have a greater potential energy than Jenn, who is lower.
what is a chemical change? and what is a physical change?
In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
A chemical change is a change where something new can be formed and normally can not be changed back. Examples of a chemical change are precipitates being formed, gases being formed, quick temperature change rust, bubbling, foaming, burning, etc. A physical change is a change where nothing new is formed and normally can be changed back. For example you painted a wooden block red. If you want, you can always change the color again. Nothing chemically or permanantly happened to it. More examples of a physical change are; color change, change of state, luster, shape, size, hardeness, etc.

Drag the tiles to the correct boxes to complete the pairs.
Match the genetic mutations with their names.
Answer:
See below!
Explanation:
Translocation ⇒ CCGGTT + TTAGGC = CCGGTA + GTTGGC
A translocation is a change in location between two chromsomes.
Inversion ⇒ CTTAAT = TAATTC
An inversion is when a gene is flipped.
Deletion ⇒ CGAGGTT = CGTT
A deletion is when a part of gene is deleted.
Duplication ⇒ ATTCGG = ATTCGGATTCGG
A duplication is when a gene is duplicated.
Insertion ⇒ CTTAAT = CTTAACGCT
An insertion is when nucleotide bases are inserted into a gene.
Substitution ⇒ CGAT = CTAT
A substitution is when part of a gene is replaced with a different base pair.
What does supersaturated mean?
A.The solvent is holding as much solute as it can
B.The solvent can hold more solute
C.There is more solute than the solvent can hold
Explanation:
There is more solute than the solvent can hold (C).
It may be harmful when people compete to see who can hold their breath the longest underwater. Without oxygen, brain cells *
Answer: Without oxygen, brain cells cannot make enough ATP.
Explanation:
Hypoxia is a condition that occurs due to low levels of oxygen. In conditions such as holding of breath for a long period of time, the oxygen carrying haemoglobin ( oxyhaemoglobin) breaks down, releasing oxygen to the body tissues, which constantly consumes oxygen keeping the levels low.
In the presence of decreased oxygen supply, autoregulatory mechanisms that control the blood flow to the brain by adjusting the diameter of the arterioles fails. The consequent rapid decrease in the cerebral blood supply leads to hypoxia and lack of glucose( decreased ATP production). If severe hypoxia is sustained for more than a few minutes, this could lead to irreversible brain damage.
Therefore, It may be harmful when people compete to see who can hold their breath the longest underwater.
Without oxygen, brain cells die as a result of the cells being unable to
metabolize glucose.
The brain is an important organ that controls almost all the activities that
takes place in the body. They have cells which converts the glucose to
energy which is needed for day to day activities.
When there is no oxygen, glucose isn't metabolized and energy is deficient.
The brain cells won't be able to function and then causes its cells to die
thereby resulting in brain damage.

There will be positive acceleration
d.
Velocity will change, but not acceleration
Answer:
There will be negative acceleration.
Explanation:
I majored in Physics
Answer:
A. There will be no change
Explanation:
Velocity is defined as the directional speed of an object in motion. Balanced forces do not result in any change in motion. Thus, there would be no change in velocity.
Please help me answer Question 1.
Answer:
9 moles of oxygen are produced from 6 moles of potassium chlorate.
Explanation:
Given data:
Number of moles of KClO₃ = 6 mol
Number of moles of oxygen produced = ?
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
now we will compare the moles of KClO₃ and O₂.
KClO₃ : O₂
2 : 3
6 : 3/2×6 = 9
Thus, 9 moles of oxygen are produced from 6 moles of potassium chlorate.
