metallic bonding in a group three metal

Answers

Answer 1

Answer: In a pure metal, there are atoms that are surrounded by free moving valence electrons in which they move from one part of metal to another part . There for we can conclude that pure metals are held together by things called metallic bonds and due to attraction between the mobile valence electrons and the positively charged metal ions.

Explanation:

Answer 2

The ability to be drawn into thin sheet is called malleability. The ability to be drawn into thin wires is called ductility. Therefore, the metallic bonds is between metals and metals.

What is metallic bonding?

Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions.

Covalent bonds are not strong bond. They can not have malleability and ductility. Ionic bonds are very strong bond. These are too not malleable or ductile. Lewis structure is used to show valence electron of every element in a molecule so, it has nothing to do with malleability and ductility. Due to metallic bonding, there is high melting and boiling point.

Therefore, the metallic bonds is between metals and metals.

Answer:

By their properties ;)

Explanation:

[tex]\Large \boxed{\sf by \ their \ properties}[/tex]

Every element has a set of particular characteristics. Each has a unique atomic and mass number because they contain a different ratio of protons and neutrons. The number of protons in an element mirrors the element's atomic number. The mass number equals the sum of the element's protons and neutrons.

According to increasing atomic numbers, chemical elements get organized. Periods and groups are the names of the horizontal rows and vertical columns, respectively. The chemical characteristics of elements within the same group are comparable due to their similar valency and number of outer electrons.

Answers

The equilibrium constant of the reaction is 0.042.

The reaction equation is given as;

PCl5(g) ⇄ PCl3(g) + Cl2 (g)

Recall that this equation shows the decomposition of phosphorus pentachloride.

We have the following equilibrium concentrations;

[PCI5]= 0.0095 M

[PCI3] = 0.020

[CI2] = 0.020 M

The equilibrium constant, K is obtained from;

K =  [PCI3]  [CI2]/[PCI5]

K = [0.020]^2/[0.0095]

K = 0.042

If 12.7 grams of hydrogen reacted with an unknown amount of oxygen, how many grams of water would be produced? (Write a balanced equation and show your work under the equation)

Answers

Answer:

    2H2    +   1 O2   ------>    2H2O

m = 12.7g                              m = ?

Get the number of moles for Hydrogen gas (H2) by dividing the mass by the molar mass (1.01g/mol as listed in the periodic table for its atomic mass)

12.7/1.01 = 12.57 mol of H2

Now use the mole to mole ratio of Hydrogen gas (H2) and water (H2O).

From the balanced equation, we can see that 2 mol of H2 gives us 2 mol of H2O. Since both of the ratios are equal (2:2), the moles we have for hydrogen gas is the same as the moles we get for water.

12.57 mol of H2O

Now that we have the amount of mol for H2O produced in this reaction, we can convert it to grams by multiplying the moles by the molar mass.

Molar mass of H2O = (1.01 x 2) + (16) = 18.02g/mol

12.57 x 18.02 = 226.5g (rounded)

Therefore 226.5g of water will be produced in this reaction

According to law of conservation of mass and stoichiometry, 114.3 g of water are produced if 12.7 grams of hydrogen reacted with an unknown amount of oxygen.

What is law of conservation of mass?

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

2 H₂ + O₂[tex]\rightarrow[/tex] 2 H₂O,according to this equation,4 g hydrogen reacts with 32 g oxygen to give 36 g water, thus 12.7 g of hydrogen will produce 12.7×36/4=114.3 g water and hence for this amount of water to be formed  12.7 g of hydrogen reacts with 101.6 g of oxygen which is obtained as 114.3-12.7=101.6 g

Thus, 114.3 g of water is produced.

How many grams of water are needed to absorb 456 J if its temperature goes from 22.7 to 98.3 Celsius?

Answers

The mass of water needed to absorb 456 J is 1.44 g

We'll begin by calculating the change in the temperature of the water.

Initial temperature of water (T₁) = 22.7 °C

Final temperature (T₂) = 98.3 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 98.3 – 22.7

ΔT = 75.6 °C

Finally, we shall determine the mass of the water

Heat absorbed (Q) = 456 J

Change in temperature (ΔT) = 75.6 °C

Specific heat capacity of water (C) = 4.184 J/gºC

Mass of water (M) =?

Q = MCΔT

456 = M × 4.184 × 75.6

456 = M × 316.3104

Divide both side by 316.3104

M = 456 / 316.3104

M = 1.44 g

Therefore, the mass of the water is 1.44 g

A solution is prepared by dissolving 15.0 g of table salt in 70.0g of water. Find(a) the mass percent of solute and (b) the mass percent of solvent. ​

Answers

Answer:

[(15g NaCl/(70+15)]*100 = % NaCl

{(70g H2O/(70+15)]*100 = % H2O

Explanation:

A solution is prepared by dissolving 15.0 g of table salt in 70.0g of water. (a) The mass percent of solute is 17.64 % and (b) The mass percent of solvent is 82.35 %.

How to calculate the Mass percent of solute ?

Mass percentage = [tex]\frac{\text{Mass of solute}}{\text{Mass of solute + Mass of solvent}}[/tex]  × 100

How to calculate the Mass percent of solvent ?

Mass percentage = [tex]\frac{\text{Mass of solvent}}{\text{Mass of solute + Mass of solvent}}[/tex] × 100

Here,

Mass of solute (table salt) = 15.0 g

Mass of solvent (water) = 70.0 g

(a) The mass percent of solute

Put the value in above formula we get

Mass percentage = [tex]\frac{\text{Mass of solute}}{\text{Mass of solute + Mass of solvent}}[/tex] × 100

                             = [tex]\frac{15}{15 + 70}[/tex] × 100

                             = [tex]\frac{15}{85}[/tex]  × 100

                             = 17.64 %

(b) The mass percent of solvent

Mass percentage = [tex]\frac{\text{Mass of solvent}}{\text{Mass of solute + Mass of solvent}}[/tex] × 100

                             = [tex]\frac{70}{15 + 70} \times 100[/tex]

                             = [tex]\frac{70}{85} \times 100[/tex]

                             = 82.35 %

Thus, we can say that (a) The mass percent of solute is 17.64 % and (b)  The mass percent of solvent is 82.35 %.

a vessel contains 66 g co2 and 16 g o2 at a pressure of 10.0 atm. what is the partial pressure of co2?

Answers

This question is providing the masses of carbon dioxide and oxygen gases at 10.0 atm as 66 g and 16 g respectively, and is asking for the partial pressure of the former which turns out to be 7.50 atm after doing the math.

Thus, we can start solving this problem with the Dalton's law approach, in order to make a relationship for the total pressure, partial pressure and mole fraction, which means we must first determine the mole fraction of carbon dioxide gas in the mixture as shown below:

[tex]x_{CO_2}=\frac{n_{CO_2}}{n_{CO_2}+n_{O_2}}[/tex]

Next, we calculate the moles of both gases by dividing the grams over the molar masses:

[tex]n_{CO_2}=\frac{66g}{44.01g/mol} =1.50mol\\\\n_{O_2}=\frac{16g}{32g/mol} =0.5mol[/tex]

Then, the mole fraction of carbon dioxide as the required one by plugging in the previously calculated moles:

[tex]x_{CO_2}=\frac{1.5}{1.5+0.5}=0.75[/tex]

Finally, we use the definition of the Dalton's law to calculate the partial pressure of carbon dioxide gas in the binary mixture:

[tex]P_{CO_2}=x_{CO_2}P\\\\P_{CO_2}=0.75*10.0atm\\\\P_{CO_2}=7.50 atm[/tex]
