in three to five sentences, predict the bonding activity between phosphorus and chlorine. why do you think they would bond that way?​

Answers

Answer 1

The bonding activity that occurs between phosphorus and chlorine is Covalent Bonding

Covalent bonding is an interaction between two atomic elements that share electrons between themselves.

In Phosphorus Pentachlorine PCl₅, covalent bonding occurs between Phosphorus and Chlorine.

This is because, Phosphorus is the central atom that is attached to 5 different chlorine atoms, each chlorine atom needs one electron each to complete its octet rule and since phosphorus has five valence electrons in its outermost shell, it shares it with each of the chlorine atoms.

How many moles of AgCl can form from 6.5 moles of Ag and abundant HCl in the equation: 2Ag + 2HCl -> 2AgCl + H2

Answers

6.5 moles of AgCl can be formed from 6.5 moles of Ag.

STOICHIOMETRY:

According to this question, silver reacts with hydrochloric acid to form silver chloride and hydrogen gas as follows:

2Ag + 2HCl → 2AgCl + H2

Based on this balanced equation, 2 moles of silver (Ag) produces 2 moles of silver chloride (AgCl).

This means that 6.5 moles of Ag will produce (6.5 × 2)/2 = 6.5 moles of AgCl.

Calculate the density of sulfur dioxide gas (SO2) at 147°C and 29.9 kPa.

Answers

The density of the gas is obtained as  0.55 g/L.

We can find the density of the gas using the relation;

PM = dRT

P = pressure of the gas

M = molar mass of the gas

d = density of the gas

R = gas constant

T = temperature

Now;

P = 29.9 kPa

R = 8.314 L·kPa mol·K.

T =  147°C + 273 = 420 K

d = ?

M = 64 g/mol

Substituting values;

d = PM/RT

d =  29.9 kPa ×  64 g/mol/ 8.314 L·kPa mol-1K-1 420 K

d = 1913.6/3491.88

Calculating Heat during Phase Changes

question below in photo :)

Answers

Answer:

Q1= 9.42

Q2= 227 KJ

Q3= 31.4 KJ

Qt=269 KJ

Explanation:

First you have to find the heat needed to make ice at a temperature of -45 C to pass to a temperature of 0 C.

You're given the formula so all you have to do is replace by the data you're given (remember to make the Celsius, Kelvin by adding 273.15 to the Celsius since the magnitudes of temperature they're giving you in the constants are the Kelvin)

Q1= (2.093 J/gxK)(100 g)(45 K)

Q1=9418.5 J

Q1=9.4185 KJ≈9.42 Kj(you're asked to give your answer in KJ)

You know have to find the energy needed to liquify the ice, in other words you need to use the enthalpy of fusion to determine the energy that's being used, and since you have 100 grams of water, you only need to find the number of moles present in 100 grams of water by dividing the number of grams by the molar mass of water (18 g/mol) and then replace in the equation.

Q2=(5.56 mol)(40.7 KJ/mol)

Q2=227 KJ

You know have to find the energy needed to raise the temperature of water from 0 C to 75 C. You do the same thing as you did in the first step:

Q3=(4.184 J/gxK)(100 g/)(75K)

Q3=31380 J

Q3=31.38 KJ≈31.4 KJ

For the final step, you only add the Qs of each step:

9.42KJ+227KJ+31.4KJ= 267.82 KJ ≈ 267.8 KJ

Why do you use these procedures?

Well, you could simply have made a unique equation at first sight that involved the changes of temperature from -45 C to 75 C, but you have a phase change in the middle. Phase change keep temperature constant but they require heat from the surroundings in order to, in the case of ice, break the bonds that keep the molecules tight together.

This heat required from the surroundings is the Enthalpy of phase change, in this case enthalpy of fusion.

3.How many moles of CO2 gas are in a 101.25 L container filled with CO2 gas?


4.What is the mass of 13.7 moles of N2 gas?


5.How many moles are in 78.5 molecules of CaCO3?

Answers

Answer:

1) Molar mass of NaOH can be calculated by taking the atomic mass values in the periodic table. Na (Sodium) = 22.98g/mol, O (Oxygen) = 16g/mol, H (Hydrogen) = 1.01g/mol

Add all the the mass values together for NaOH's molar mass, so (22.98 + 16 + 1.01) = 39.99 or round it to 40g/mol

2) To find the atoms from the moles, you just multiply Avogadro's number (6.02 x 10^23) by the moles.

So 3.35 x (6.02 x 10^23) = 2.0167 x 10^24 atoms are in 3.35 moles of aluminum

3) If the question is asking under standard temperature and pressure, we know that if we divide the volume by the molar volume of a gas (which is 22.7 in standard temperature and pressure), we can get the moles.  

So 101.25L / 22.7 = 4.46 mol

4) We know that to find the moles, it is the mass divided by the molar mass. If we rearrange the equation to solve for mass, we have to multiply the moles by the molar mass to get there.

Nitrogen's (N) molar mass on the periodic table is 14g/mol, but since Nitrogen is a diatomic element, it would be N2 by itself. So multiply 14 by 2, which will give you 28g/mol. N2's molar mass is 28g/mol.

Now you multiply 13.7 moles by 28g/mol, which will give you 383.6g

5) Now here I think you may have wrote the question wrong. Molecules would be at a way higher number than just 78.5, so I'm first just going to assume you meant 78.5g.

To get the moles from mass, you divide the mass of the compound by its molar mass. Molar mass of CaCO3 can be just calculated using the atomic mass values for each element in the compound (Ca is 40.07g/mol, C is 14g/mol, O3 would be 16 x 3 g/mol or just 48g/mol) and then adding them all together (40.07 + 14 + 48 = 102.07) which would give us 102.7g/mol.

Now, just divide the mass 78.5g by the molar mass 102.7g/mol

78.5/102.7 = 0.764 moles

Now on the offchance that you were actually referring to molecules, and you accidentally typed a different number doing this, you can find out the moles from the molecules by just dividing the number of molecules you have with avogadro's number (6.02 x 10^23)

So it would look something like this:

molecules of CaCO3 / 6.02 x 10^23

Determine the mass of O(2-) ions in 3 mol of alumina (Al2O3). Molar mass of O = 16)

Answers

Considering the rule of three and molar mass of O, the mass of O²⁻ ions in 3 mol of alumina Al₂O₃ is 96 grams.

By multiplying the number of moles by the subscripts next to each atom, you get the amount of each element present in the compound. IIf the same atom appears more than once in the compound, you must add its amounts.

So, in 1 mole of Al₂O₃, you have 2 ions of O²⁻.

Then you can apply the following rule of three: if 1 mole of the compound contains 2 ions of O²⁻, 3 moles of the compound contains how many ions of O²⁻?

[tex]amount of ions of O^{2-} =\frac{3 moles of Al_{2} O_{3} x2 ions of O^{2-}}{1mole of Al_{2} O_{3} }[/tex]

amount of ions of O²⁻= 6 ions

Being the molar mass of O 16 g/mole, this is the amount of mass that a substance contains in one mole, then the mass of O²⁻ can be calculated as:

6 x 16 g/mole= 96 grams

Finally, the mass of O²⁻ ions in 3 mol of alumina Al₂O₃ is 96 grams.
