arrange the bromine-containing compounds cabr2, br2, asbr3, cbr4 in order of increasing normal boiling point.

Answers

Answer:

Br2, CBr4, AsBr3, CaBr2. this is the increasing order of boiling point

The arrangement of given compound in the increasing order of normal boiling point is Br₂ < CBr₄ < AsBr₃ < CaBr₂.

What is normal boiling point?

Norma boiling point of any liquid is that point where the vapor pressure is equal to the standard sea level atmospheric pressure.

And boiling point is directly proportional to the strength of bond which is present between the atoms of any compound.

As we know that ionic bond is the strongest bond and in CaBr₂ ionic bond is present so the boiling point of this compound will be highest.In AsBr₃, bromine is more electronegative than arsenic and arsenic also have one lone pair on it so some dipole moment develope in it and then this compound will have boiling point less than CaBr₂.CBr₄ is a covalent compound as in this compound bromine is present which is more electronegative but overall dipole moment of this compound is zero.Br₂ is also a covalent molecule and it has no dipole moment in it and have minimun boiling point among all compounds.

So, correct order will be Br₂ < CBr₄ < AsBr₃ < CaBr₂.

Why does atomic radii decrease as you move from the left to right across the period

Answers

Answer:

This is because, within a period or family of elements, all electrons are added to the same shell.

When we move from left to right across the periodic table, we can see that the atomic radii keeps decreasing. This is because, as you move from left to right, the nucleus gains protons. The atomic number increases and hence the valence electron will feel more attracted towards the nucleus & the atomic radii will decrease.

why is it impossible to have an undiscovered element that would fit between sodium and magnesuim

Answers

Answer:

Sodium has 11 protons and Magnesium has 12. The way that the periodic table is set up doesn't allow for any elements to be in between. The element would have to have 11.5 protons, which is impossible

Structure of periodic table is designed in a way that successive elements have difference of 1 electron and proton as sodium and magnesium have 11 and 12 protons respectively there is no space for any other element.

What is periodic table?

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.

The more impressive the tail of a male peacock, the higher its chances of finding a mate. Female peacocks choose mates based on the color of the feathers and the overall physical prowess of the animal. However, a genetic mutation called leucism can produce a peacock with only white feathers. This mutation causes the inability of pigment to be deposited into their feathers which results in a white appearance. What would you infer to be the fitness of the white peacock? Choose ALL that apply.
A) The females will equally choose the brightly colored and white peacocks as mates.
B) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, making them desirable mates.
C) If females choose the brightest males as partners, the ones without the impressive tails will be less likely to mate and reproduce.
D) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, causing them to be selectively bred for their unique trait.
E) The peacocks with colored tails will be picked over the white peacocks as mates, causing the peacocks with the white mutation to die out of the population over time

Answers

Leucism is a genetic mutation caused by an alteration of a nucleotide. The less brightly colored tails of the peacock will have less chance to mate.

What is selection?

Selection is the natural process in which the organism with better trait quality is preferred and selected over another species. They are fit to survive in an altered condition.

The genetic mutation can lead to speciation and selection of the fittest organisms. The type of behavior selection results in the preference of the partners based on the mating and reproducing capabilities.

Therefore, option C. the peacock without impressive tails will be less likely to mate and reproduce.

Answers

The enthalpy of reaction for the decomposition of calcium carbonate is 177.4  KJ/mole .

We know that the enthalpy of reaction can be obtained from the enthalpy of formation of the reactants and that of the products using the formula;

ΔHrxn = ΔHf (products) - ΔHf (reactants)

The heat of formation of the species are as follows;

ΔHf (CaCO3(s)) = −1206.9 KJ/mol

ΔHf (CaO(s)) =  - 636 KJ/mole

ΔHf (CO2(g)) = -393.5  KJ/mole

ΔHrxn = [( -393.5  KJ/mole ) + ( - 636 KJ/mole)] - [ −1206.9 KJ/mol]

Moles of Cu present = 19.0 g Cu x 1 mole Cu/63.55 g = 0.2990 moles Cu
Moles AgNO3 = 125 g AgNO3 x 1 mole AgNO3/169.9 g = 0.7357 moles AgNO3
Which reactant is limiting? It will be Cu because the mole ratio is 2 AgNO3 to 1 Cu and there is more than enough AgNO3. Thus, amount of Ag formed will depend on moles of Cu (0.2990)
Moles of Ag formed = 0.2990 moles Cu x 2 moles Ag/mole Cu = 0.598 moles Ag

The balanced equation for this process is shown below. 3H2 N2 Right arrow. 2NH3 The molar mass of NH3 is 17. 03 g/mol. The molar mass of H2 is 2. 0158 g/mol. In a particular reaction, 0. 575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures? 0. 1 0. 102 0. 10209 0. 1021.

Answers

Answer:

B

Explanation:

We are given that ammonia can be produced from hydrogen gas and nitrogen gas according to the equation:

[tex]\displaystyle 3\text{H$_2$} + \text{N$_2$} \longrightarrow 2\text{NH$_3$}[/tex]

We want to determine the mass of hydrogen gas that must have reacted if 0.575 g of NH₃ was produced.

To do so, we can convert from grams of NH₃ to moles of NH₃, moles of NH₃ to moles of H₂, and moles of H₂ to grams of H₂.

We are given that the molar masses of NH₃ and H₂ are 17.03 g/mol and 2.0158 g/mol, respectively.

From the equation, we can see that two moles of NH₃ is produced from every three moles of H₂.

With the initial value, perform dimensional analysis:

[tex]\displaystyle \begin{aligned} 0.575\text{ g NH$_3$}& \cdot \frac{1\text{ mol NH$_3$}}{17.03\text{ g NH$_3$}} \cdot\frac{3\text{ mol H$_2$}}{2\text{ mol NH$_3$}} \cdot \frac{2.0158\text{ g H$_2$}}{1\text{ mol H$_2$}} \\ \\ & = 0.102\text{ g H$_2$}\end{aligned}[/tex]

*Assuming 100% efficiency.

Our final answer should have three significant figures. (The first term has three, the second term has four (the one is exact), the third term is exact, and the fourth term has five. Hence, the product should have only three.)

In conclusion, our answer is B.

what is the mass of 3.0 x x times 10^23 atoms of neon?

Answers

Answer:

10.09 grams

Explanation:

First you need to know the number of moles you are dealing with.

If you know that each mole has 6.022x10²³ of something (in this case of atoms), you can divide 3x10²³ atoms of neons by 6.022x10²³ to obtain the number of moles.

You have 0.5 moles of Neon, so then by the periodic table, you see that the molar mass of neon is 20.18g/mol, so by each mole you have 20.18 grams of neon. Multiply 20.18 grams by 0.5 moles and you got 10.09 grams of Neon
