which properties of a system would determine whether vacancy or interstitial diffusion is more likely?

Answers

The size of the particles decides whether vacancy or interstitial diffusion is more likely.

In vacancy diffusion, the atoms moves in a particular direction and the vacancies are filled and new vacancies are created on the places of the atoms.

While in Interstitial diffusion, the atoms moves inside the lattice of the structure of the crystals.

Interstitial diffusion is faster than vacancy diffusion because it is easier to move inside the lattice, and if the size of the atom is small, it will prefer interstitial diffusion over vacancy diffusion. So, smaller the size of the atoms, faster is the rate of interstitial diffusion.

if 9.65 g of nacl reacts with excesses of the other reactants and 4.11 g of nahco3 is isolated, what is the percent yield of the reaction?

Answers

The percent yield of the reaction  is  28.60 %

The first step for this problem is to convert the given 10.0 grams of NaCl to moles using the molar mass of NaCl:

9.65 g of NaCl = 9.65/58.5

                        = 0.165 moles of NaCl

Next, we look at the balanced reaction equation and determine how many moles of NaHCO3 we could potentially make without 0.165  moles of NaCl (this is called the "theoretical yield"):

0.165 moles NaCl × 1 mol NaHCO₃/1 mol NaCl

                            = 0.165 moles of NaHCO₃

Next, we convert the 0.165  moles of NaHCO3 theoretical yield to grams so that we can compare this to our "actual yield" of 4.11 grams:

0.165 moles of NaHCO₃ × 84 gtrams/1 mole

                        = 13.86 grams of  NaHCO₃

Finally, we compare our theoretical yield of 13.86 grams to our actual yield of 4.11 grams and multiply by 100 to get our percent yield:

4.11 grams / 14.37 grams × 100 = 28.60 %

Answers

A chemistry graduate student combines 3.90 grams of potassium and 12.7 grams of iodine to form potassium iodide. according to the law of conservation of mass, potassium iodide should be formed after the reaction is complete is 16.70 g.

According to the law of conservation mass, in a chemical reaction mass can neither be created nor destroyed.

According to the law, mass of the reactant is always equal to the mass of product, because in a chemical reaction, mass can neither be created nor destroyed.

The balanced chemical reaction is -

2 K      +       I₂    →      2 KI

3.90 g  +   12.7 g   =   16.70 g

16.70 g                  =   16.70 g

Therefore, when the reaction proceeds to completion, 16.70 g product is obtained as the sum of reactants is 16.70 g and according to law of conservation of mass, mass is neither created nor destroyed but it only converts from one form to another form.

Elements that have an intermediate number of valence electrons will behave more like metals if they are?

Answers

Elements that have an intermediate number of valence electrons will behave more like metals if they are lower in group .

What is metal ?

In chemical processes, metals frequently lose electrons. In chemical reactions, nonmetals pick up electrons. When they are lower in the group and higher in the group, elements with an intermediate amount of valence electrons behave more like metals and less like nonmetals, respectively. They will act as metalloids if they are in the middle.

The elements that make up the periodic table are metals, nonmetals, and metalloids. Metals tend to lose electrons in chemical reactions because they are electropositive.

Because of the weak nucleus-based attraction, lesser elements can easily lose electrons from the valence shell.

What are valence electrons ?

The amount of electrons an atom must gain or lose in order to achieve the electrical configuration of the nearby noble gas or inert gas is known as valence. "Valence electrons" are described as "non-filled electrons in the outer shells."

Because they have higher energy than the electrons in inner orbits, valence electrons participate in chemical reactions. A specific element's chemical characteristics, such as its valence or valency and the ability to form bonds with other elements, can also be determined by the quantity of valence electrons that are present. It also provides us with information on the quantity of unpaired electrons, the number of atoms that can participate, and how easily the atoms can make bonds.

explain the difference in boiling points between water and methane in terms of intermolecular forces present​

Answers

Answer: Water has a higher boiling point than methane. Water has a higher boiling point because water molecules have hydrogen bonds, which means MUCH STRONGER intermolecular forces, than methane.

Methane and water have different boiling points. Because water molecules have hydrogen bonds, which equate to much stronger intermolecular interactions than methane, water has a higher boiling point than methane.

What is the boiling point?

The temperature at which a liquid's vapor pressure matches the pressure surrounding the liquid is known as the boiling point of that substance.

An O-H bond has a bigger bond dipole than a C-H bond because oxygen is more electronegative than carbon. As a result, there is a stronger force of attraction between two water molecules than between two methane molecules.

Therefore, the boiling points of water and methane are dissimilar. Water has a greater boiling point than methane because water molecules have hydrogen bonds, which translate to far stronger intermolecular interactions.

A sample of gas occupies a volume of 450.0 mL at 740 mm Hg and 16°C. Determine the volume of this
sample at 760 mm Hg and 37°C.

Answers

The volume of this sample at 760 mm Hg and 37°C is 474.92 mL.

How to calculate volume?

We know that,

PV = nRT, the fundamental law of ideal gas.

Where P is the gas's pressure in atmospheres.

The gas's volume in L is denoted by V.

n is the number of moles of the gas in a mole.

The general gas constant is R.

The gas's temperature is T in Kelvins.

If n is constant and (P, V, and T) have two different values:

P1V1T2 = P2V2T1

P1 is 740 mmHg, V1 is 450 mL, and T1 is 16 °C plus 273 K.

P2 equals 760 mmHg, V2 is??? mL, and T2 is 37 °C plus 273 K, or 310 K.

V2 = P1V1T2/P2T1 = (740 mmHg), 450 mL, 310 K), and 760 mmHg, 286 K) = 474.92 mL, respectively.

Which of the following pairs of elements would you expect to form a polar
covalent bond?
N and P
S and S
Ba and S
B and H

Answers

N and P pairs of elements would you expect to form a polar covalent bond.

What is a covalent bond ?

A covalent bond is formed when two atoms exchange one or more pairs of electrons. The two nucleus are concurrently drawing these electrons to them. When the difference between both the electronegativity values of two atoms is too tiny for a transfer of electrons to actually occur to create ions, a covalent bond is formed.

How are covalent bonds represented?

Covalent bonds between atoms in a Lewis structure are shown as a single line connecting the two atoms, which corresponds to the chemical symbol for the element. Diatomic molecules including hydrogen, nitrogen, fluorine, chlorine, bromine, iodine, and astatine are the principal sources of covalent bonding.
