The elements should be label as follows yellow = OH, blue = Fe, green = Ba, red = Cl
The mix between aqueous barium hydroxide and aqueous iron chloride leads to barium chloride and iron hydroxide. This reaction is shown below:
Ba(OH)2 + FeCl3 → BaCl2 + Fe(OH)3Moreover, in these products, the iron hydroxide will form a solid substance that precipitates in the bottom of the container, while the barium chloride is more likely to maintain its liquid state.
According to this, the substance in the bottom is the iron hydroxide or Fe (OH)2, and in this, the yellow dots represent the Hydroxide or OH, while the blue dots are the Iron considering there in iron hydroxide there are two molecules of OH for each molecule of iron.
On the other hand, at the top, there is the barium chloride or BaCl2. This means the green dots are the Barium and the red ones are the Chlorine as there should be more Chlorine particles than Barium ones

Which of the following resources can be obtained from the hydrosphere?
What particles would you find in a nucleus of an atom
Answer:
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

Drag electrons back and forth until the molecule of oxygen (O2) is stable. Click Check to confirm your molecule is stable. How many pairs of shared electrons are there in a stable molecule of oxygen?
Answer:
2 pairs (4 electrons)
Explanation:
In a molecule of oxygen there are 2 oxygen atoms. There are 6 electrons in the outer shells of oxygen atoms. When 2 oxygen atoms form a covalent bond they share their electrons. In a diagram this would be represented by the overlap of the two circles representing the outer shells of both oxygen atoms. If each oxygen atom 'puts forward' 2 electrons into the centre, then 4 will be shared overall for each atom, making both atoms have full outer shells of 8 electrons each. 4 electrons make 2 pairs, hence the answer.
Is each ion stable? Explain.
Answer:
By satisfying the duet rule or the octet rule, ions are more stable.
Explanation:
Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable.
The octet rule states that an atom is most stable when there are eight electrons in its valence shell. Atoms with less than eight electrons tend to satisfy the duet rule, having two electrons in their valence shell. By satisfying the duet rule or the octet rule, ions are more stable.

Explain why you would want to keep some, but not all, receipts as part of your financial records.
Answer:
Explanation:
Let's try and figure out the ones you don't keep.
Receipts from the dollar tree. You can't return what you bought and you only paid a dollar. It's not worth it.
Food receipts. You can't return it and unless you want to itemize what you spend / month and on what, they don't serve any purpose.
Now figure out which ones you would want to keep
1. Anything pertaining to medical perscriptions. I don't know how it works in the United States, but in Canada we are allowed to deduct only medications with a DIN number.
2 Anything that you would use for travelling that is not for pleasure (ie it is a business expense). So if you are a salesman and your territory is from A to B you would deduct meals, mileages, motels if you must stay away from home
3 In the states some tax receipts are deductible, so you might want to save those.
Which of the following sets of quantum numbers is not allowed?
A.) n=3, l=2, ml=-2
B.) n=4, l=3, ml=-3
C.) n=2, l=1, ml=-1
D.) n=2.5, l=0, ml=0
E.) n=3, l=2, ml=-1
Answer:
D) n = 2.5, ℓ = 0, mℓ = 0
Explanation:
According to the rules governing acceptable quantum numbers, the value for n must be an integer. Therefore, the set {n = 2.5, ℓ = 0, mℓ = 0} is not allowed.

Which statement best explains why mass is not conserved in a nuclear change?
Some of the products have less mass than the reactants.
Some of the reactants are not used.
Some of the atoms are lost in the reaction.
Some of the matter is converted to energy.
The statement that best explains why mass is not conserved in a nuclear change is that; "some of the matter is converted to energy".
In a nuclear reaction, mass is converted to energy. This is the energy that is given out when a new nuclide is formed during a nuclear reaction.
Generally, the scheme of a nuclear reaction is; Parent nucleus + Bombarding particle -------> Daughter nuclei + product particles + energy. This energy is obtained when mass is lost from left toi right in the reaction.
Hence, the correct answer is; some of the matter is converted to energy".
