Draw arrows for all of the attractive and repulsive forces between the negatively charged electrons and positively charged protons in these atoms. Make sure your arrows clearly show the difference between attractive and repulsive forces. Note that the particles without a charge label are neutral.

Answers

Answer:

Attraction

(e-) ---> <--- (H+)

Repulsion:

<---(e-) (e-)-->

Neutral:

(e-)       (Helium)

Explanation:

Accordingly to coulomb's law:

In the attraction, the hydrogen without an electron has a positive charge and needs to be fulfilled with a negative charge found in an eletron.

In the repulsion, both electrons has the same charge and repulse each other.

In the neutral case, the Helium is highly stable therefore the electron is not attracted.

A supercontinent is a landmass that consists of an aggregate mass of entire earth lithospheric landmasses. Pangaea was the last supercontinent that split about 200 million years ago.

The German geologist Alfred Wegener gave numerous pieces of evidence to support his theory of continental drift. These theories include fossil records, glacial chains, coal despites. In some places, he has also mentioned the presence of a similar climate type.

Two piles of heavy boxes must be lifted onto a shelf. Each pile has 20 boxes and each box is the same size and weight. Tom and Claudia are each responsible for a pile. Tom lifts each box straight up from the pile to the shelf. Claudia places a long, gradual ramp that leads from the pile to the shelf. She pushes each box up the ramp until it rests on the shelf.

(Tom used more force.)

Simply because we see Claudia used a shortcut. Tom uses more physical force than Claudia, since Claudia only had to push the boxes into there required shelves.

Use the information below to explain why the atomic radius decreases down a group.

Answers

Answer:

Detail is given below

Explanation:

Atomic radii trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

In A we can see that there is one positive charge and force of attraction is 2.30×10⁻⁸ N and distance is 0.10 nm

In B we can see that negative charge is further away from nucleus because of greater distance thus force of attraction will be less. 0.58×10⁻⁸ N

In C this distance further increases and force also goes in decreasing 0.26×10⁻⁸ N.

What is the chemical formula for the limiting reactant in the reaction shown? Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

Answers

1. What is the chemical formula for the limiting reactant in the reaction shown?

Answer: NO

2. Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

Answer: 2NO + 2H2 —-> 2H2O + N2

Taking into account the definition of limiting reagent and balanced reaction, you get:

NO is the limiting reagent.The balanced reaction is 2 NO +  2 H₂ → 2 H₂O + 1 N₂What is the chemical formula for the limiting reactant in the reaction shown?

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

The reagent in excess will be the one that is not completely exhausted during the reaction, that is, they are those that are partially consumed, "excess" amount of that reagent. This is because the amount of product obtained from the reaction will always depend on the amount of limiting reagent in the reaction.

In this case, you can see that you have two reactants: NO and H₂. Having 4 moles of NO and 5 moles of H₂, you can see that no moles of NO are present in the products, but there is 1 mole of H₂.

This indicates that NO is the limiting reagent, since it is completely consumed, while there is 1 mole of H₂ in excess.

In summary, NO is the limiting reagent.

Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

Taking into account that the reagents are in stoichiometric proportions when the reagents are combined with each other without any of them,  you can observe that the chemical equation is:

4 NO +  4 H₂ → 4 H₂O + 2 N₂

Dividing by 2 to get the lowest whole-number coefficients, the balanced chemical reaction is:

2 NO +  2 H₂ → 2 H₂O + 1 N₂

You have a graduated cylinder with 10 mL of water in it.
You add 300 g of lead weights, and the volume of the
water rises to 40 mL. What is the density of the lead?

Answers

Answer:

The answer is 10 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 300 g

volume = final volume of water - initial volume of water

volume = 40 - 10 = 30 mL

We have

[tex]density = \frac{300}{30} = \frac{30}{3} \\ [/tex]

We have the final answer as

10 g/mL

Answers

Each atom/element has an electron configuration

The electron configuration shows the energy level of the electron

Each electron configuration has 4 quantum numbers, namely n, l, ml, and ms

n = the principall = the angular momentum / azimuthal ml = the magnetic ms = the electron-spin

We make an example of the element Mg which is in group 2 with the atomic number 12

Electron configuration of Mg: [Ne] 3s² or 1s² 2s² 2p⁶ 3s²

if Mg removes 2 electrons then Mg will form a positive ion (cation) Mg²⁺

This cation is included in the monatomic ion because it is formed from one element (in contrast to the polyatomic ion, which is formed from two or more elements such as SO₄²⁻, ClO₃⁻)

Electron configuration of Mg²⁺ : 1s² 2s² 2p⁶

So atoms can be positively or negatively charged depending on removing or attracting electrons

HELPPPPPText (for the second one)The captains needed to keep the slaves in acceptable physical condition if they were to be sold at high prices, so each morning after breakfast the slaves were danced on deck, in order to give them exercise. Still shackled together, the men were forced to jump up and down until often the flesh of their ankles was raw and bleeding from the iron chains from which bound them together. The women and children, who were free of such bonds were better able to dance to the rhythm that was pounded out on an African drum or iron kettle, sometimes with the accompaniment of a fiddle or African banjo played by a crew member. The slaves, otherwise kept miserable in the tween decks, enjoyed this dancing, as it was their only form of physical recreation during the entire day. Each day at sunset the slaves would be placed back below deck to rest in the misery and filth that was the tween decks. QUESTION:2. What does this text reveal about the first Africans to be brought to North America?Text (for the third question)During the morning exercises members of the crew roved about the deck carrying whips and would beat those slaves who refused to dance. Although most whips were made only of simple rope, the wicked cat-o-nine-tails was used aboard many slavers.

During the storms the blacks were forced to remain below deck all day and night. The holds were dark, filthy, slimy, and they stank of death. The tween decks were often full not only with slaves, both living and dead, but also with blood, vomit, urine, and human waste. Also during periods of inclement weather the slaves were not fed as usual. They were often forced to scrounge for small crumbs and pieces of spoiled food and drink from stagnant puddles of extremely pure water.QUESTION:5. What does this text reveal about the first Africans to be brought to North America?TEXT (for the sixth question)During the periods of good weather, the slaves would be brought up on deck in the morning. At this time the men would be shackled together with iron chains, while the women and children would be allowed to roam about on deck. At about nine o clock in the morning they were given their first meal of the day. Interestingly, slaves from different sections along the West African coast would often be fed different meals. Those from the Northern part of the Guinea coast would be fed boiled rice, millet, or cornmeal. Slaves from the Bight of Biafra had stewed yams, and those from still farther south in the Congo River region would be fed starchy manioc, cassava flour, or banana-like fruits. Sometimes a few lumps of raw meat would be thrown in with their food to keep them healthy. It was also at this time in the morning that the slaves were given their daily ration of a half-pint of water in a small pan, called a pannikin.In the late afternoon came the slaves second and only other meal of the day. Sometimes it was the same as their first, but most captains were not that humane. The afternoon meal usually consisted of horse beans, very large beans which are used to feed horses.
