Gas --> separated particles, usually a great amount away from each other

Liquids --> particles are closer together but not always touching

Solids --> particles are solidly packed together, not one is distant

hope this helped, have a fantastic night/day/morning :)

One mole of silver has a mass of 107.9 grams. Approximately how many atoms of silver are present in one mole of silver?

irga5000 [103]

Answer:

The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.

Explanation:

Step 1: Data given

Mass of 1 mole silver = 107.9 grams

Step 2: Calculate the number of atoms in 1 mole of silver

To calculate the number of atoms in 1 mole, we multiply the number of Avogadro by the number of moles

Number of atoms = 1 mol * 6.022 *10^23 atoms/ mol

Number of atoms = 6.022 * 10^23 atoms

Since the number of Avogadro says there are 6.022 * 10^23 atoms per 1 mole. The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.

Which of these statements about alloys and intermetallic compounds is false? Which of these statements about alloys and intermet

Black_prince [1.1K]

The statement that is an alloy is just another word for a chemical compound of fixed composition that is made of two or more metals is false.

An alloy refers to the mixture of the elements in which the parent element is the metal. An alloy is produced by the amalgamation of any element, that is, metal or non-metal to better the feature of the parent metal. The whole components in the alloy are combined to produce a mixture of fixed composition, but not a chemical compound, and it is not essential that the elements involved are metals. Thus, the mentioned statement is false.

Consider the molecules: scl2, f2, cs2, cf4, and brcl. select the choice where the bonds of the molecules are arranged in order o

elena-s [515]

The polarity of a bond depends on the difference in electronegativities of the atoms involved in bonding. Greater this difference, greater is the polarity

1) In SCl2 we have the S-Cl bond

Electronegativity values: S = 2.5, Cl = 3

Difference = 3.0 -2.5 = 0.5

2) In F2 we have the F-F bond

Electronegativity value: F = 4.0

Difference = 4.0-4.0 = 0

3) In CS2 we have the C-S bond

Electronegativity value: C = 2.5, S = 2.5

Difference = 2.5 -2.5 = 0

4) In CF4 we have the C-F bond

Electronegativity values: C = 2.5, F = 4.0

Difference = 4.0 -2.5 = 1.5

5) In BrCl we have the Br-Cl bond

Electronegativity values: Br = 2.8, Cl = 3

Difference = 3.0 -2.8 = 0.2

Therefore, the increasing order of polarity is

F2 = CS2 < BrCl < SCl2 < CF4

I just started learning about kinetic molecular theory, and I’m not sure how to answer the question circled below

lions [1.4K]

Answer : The value of 'R' is $0.0821\text{ L atm }mol^{-1}K^{-1}$

Solution : Given,

At STP conditions,

Pressure = 1 atm

Temperature = 273 K

Number of moles = 1 mole

Volume = 22.4 L

Formula used : $R=\frac{PV}{nT}$

where,

R = Gas constant

P = pressure of gas

T = temperature of gas

V = volume of gas

n = number of moles of gas

Now put all the given values in this formula, we get the values of 'R'.

$R=\frac{(1atm)\times (22.4L)}{(1mole)\times (273K)}$

$R=0.0821\text{ L atm }mol^{-1}K^{-1}$

Therefore, the value of 'R' is $0.0821\text{ L atm }mol^{-1}K^{-1}$ .
