In general, a molecule's electron pairs will take on a structure that maximizes theirs from one another.

Even charges repel one another, whereas dissimilar charges attract H₂O, for instance, containing two pairs of lone electrons but taking on an angular form.

Sand ridges, like the Lake Wales Ridge, were created during dry times from sediments that had been transported by ocean currents and deposited to form islands.

Latitude, land and water distribution, dominant winds, hurricanes, pressure systems, and ocean currents are the main variables that influence Florida's climate.

Therefore, as glaciers retreated throughout cooling cycles, sea levels dropped and Florida occasionally doubled in size.

Using your understanding of activation energy, explain why a piece of paper sitting in a 70° F room does not ignite/burn/react even though there is plenty of oxygen to go around (the cellulose of paper can react with oxygen to form carbon dioxide and water).

Answers

Activation energy is required so reactants can move together, overcome forces of repulsion, and start breaking bonds.

What is activation energy?

The minimum amount of energy that is needed to activate atoms or molecules to a condition in which they can undergo a chemical transformation or physical transport.

The activation energy of this chemical reaction is high that it will not start at room temperature. This is why a source of heat is required to start the fire: the “energy barrier” must be overcome before the reaction can proceed further.

In any chemical reaction, existing chemical bonds should be broken before new bonds formation. The breaking of chemical bonds requires an input of energy. In some reactions, the thermal energy at room temperature is enough to break the bonds.

In other cases, the thermal energy at room temperature does NOT give enough energy to break the needed bonds (by facilitating sufficiently energetic molecular collisions) to get the reaction started.

What is the Molar volume ?

The molar volume of a gas is the volume of one mole of a gas at STP.

At STP, one mole (6.02×10²³ particles) of any gas occupies a volume of 22.4 L

Therefore,

If 1 mole of any gas occupies 22.4 L of volume at STP

Then, X mole of gas occupies 7 L of Volume at STP

Now,

Let's equate both the above conditions ;

X / 7 L = 1 / 22.4 L

  X      = 1/ 22.4 L x 7 L

When 50.5 g iron(III) oxide reacts with carbon monoxide, 32.2 g iron is produced. What is the percent yield of the reaction?
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)


Answers

Taking into account definition of percent yield, the percent yield for the reaction is 91.17%.

Reaction stoichiometry

In first place, the balanced reaction is:

Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Fe₂O₃: 1 mole CO: 3 moles Fe: 2 moles CO₂: 3 moles

The molar mass of the compounds is:

Fe₂O₃: 159.7 g/moleCO: 28 g/moleFe: 55.85 g/moleCO₂: 44 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Fe₂O₃: 1 mole ×159.7 g/mole= 159.7 grams CO: 3 moles ×28 g/mole= 84 gramsFe: 2 moles ×55.85 g/mole= 111.7 gramsCO₂: 3 moles ×44 g/mole= 132 gramsMass of Fe formed

The following rule of three can be applied: if by reaction stoichiometry 159.7 grams of Fe₂O₃ form 111.7 grams of Fe, 50.5 grams of Fe₂O₃ form how much mass of Fe?

[tex]mass of Fe=\frac{50.5 grams of Fe_{2} O_{3} x111.7 grams of Fe}{159.7 grams of Fe_{2} O_{3}}[/tex]

mass of Fe= 35.32 grams

Then, 35.32 grams of Fe can be produced from 50.5 g iron(III) oxide.

Percent yield

The percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.

The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:

[tex]percent yield=\frac{actual yield}{theorical yield}x100[/tex]

where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.

Percent yield for the reaction in this case

In this case, you know:

actual yield= 32.2 gramstheorical yield= 35.32 grams

Replacing in the definition of percent yields:

[tex]percent yield=\frac{32.2grams}{35.32grams}x100[/tex]

Solving:

percent yield= 91.17%

What is a photon?

A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.

We need to find the number of photons emitted per second.

So we have E = hc ÷ λ

= (6.6 x [tex]10^-(^3^4^)[/tex]x 3 x [tex]10^8[/tex] m/s) ÷ 6.78 x [tex]10^(^-^7^)[/tex]nm

The Bohr model is a simplistic means of explaining the placement of the subatomic particles of the elements of the periodic table.

The Bohr model arrangement of electrons follows the same pattern as the periodic table.

2 elements in the first row, and 2 electrons in the first orbit.

8 elements in the second row, and 8 electrons in the second orbit.

• Both A and B will be chemically unreactive.

Answers

Answer:

The answer is "B will give up two electrons to form bonds".

Explanation:

To first solve this multiple choice question, we need to identify the Atoms, A and B.

We can do this by looking at their amount of electrons.

For instance,

A = Neon = 10 Electrons

B = Magnesium = 12 Electrons

With this information we can then look at both elements charges to see what they need to form a bond.

In this case Neon doesn't want to form a bond, since they're in a complete octet, however Magnesium does not have a complete octet. So, it wants to give up two electrons to form a bond (2+ charge shows us that).

This then shows us that Option 2, "B will give up two electrons to form bonds" is correct.

The molecule is polar if one of the requirements is met; else, it is nonpolar. The oxygen atom is a terminal atom because it surrounds the sulfur atom, which is the center element in the SO2 molecule's Lewis structure. In this molecule, there are two terminal oxygen atoms.

Empirical formula of the Cyclopropane = C[tex]H_{2}[/tex]

Molecular formula  of the Cyclopropane = [tex]C_{3} H_{6}[/tex]

Cyclopropane is a cyclic compound having 3 carbon atoms in a ring.

As we know carbon is having 4 valency, that means it can form 4 bonds with other atoms.

In case of cyclopropane each carbon atom is attached with 2 carbon atoms in a ring, so 2 valency of each carbon atom is used in a ring formation.

The remaining 2 valency are satisfied by hydrogen atoms.

Here, 3 carbons are there so 6 hydrogens are used to satisfy their valency.

An empirical formula is a simple representation of ratio of the atoms present, while a molecular formula is a detailed representation of the total number of atom.

So here, carbon and hydrogen ratio is 1:2 , from this the Empirical formula of the Cyclopropane became C[tex]H_{2}[/tex]

And the molecular formula of  the Cyclopropane is [tex]C_{3} H_{6}[/tex].

Bret is planning a long hike. He figures that he will need at least 0.75 liters of water for each hour on the trail. He also wants to have 1.8 liters of water in reserve at all times. If he can only carry 9 liters of water maximum, how many hours can he hike? I begged my little brother to clean his filthy half of the room we shared. He did nothing. I yelled that I didn't want to live in a pigsty. This, too, had no effect.

However, nomanufacturing plant is perfect and so there might be slight errors. For example, Sam's SplendidSoda company has verified that the amount of soda in their cans has a normal distribution witha mean of 12 ounces and a standard deviation of 0.7 ounces. Although this is made up, it's notcompletely divorced from the truth.1. You open a can of Sam's and realize there are only 11.6 oz in the can. What is theprobability that a single can will contain 11.6 ounces or less of soda? (2 points)2. Troubled by the under-filled soda, you decide to empty out all the cans in a six pack of Sam'sSoda and find that the mean amount of soda in all the cans is 11.6 ounces. What is theprobability that six pack will have a mean of 11.6 ounces or less of soda? (2 points)3. Not satisfied with the information you figured out in #2, you take a case (36 cans) andempty out all the cans of Sam's Soda and find that the mean amount of soda in all the cans is11.6 ounces. What is the probability that case will have a mean of 11.6 ounces or less of soda?(2 points)4. Draw three normal distributions on the same set of axes or with the same scale to showhow the probabilities decrease from one can to six cans to 36 cans even though we're lookingat "less than 11.6 ounces."
