Inter molecular forces are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions. Some include Hydrogen bonds and and Metallic bonding.

Intermolecular forces are the forces that happen between molecules. Just like an interstate is a highway that goes between different states, intermolecular forces are forces are forces between different molecules.

Hydrogen bonds are the strongest of the intermolecular forces.

The new volume of the bag will be 789.5 mL.

Explanation:

As per the Charles law, at constant pressure the volume of the gas is directly related to its temperature in Kelvin (K). That is as the temperature increases, the gas expands and vice-versa.

$$\frac{V1}{T1} = \frac{V2}{T2}\\$

V1 = 250 ml

V2 = ?

T1 = 19° C

T2 = 60° C

Now we have to rewrite the equation to get the new volume as,

V2 = $$\frac{V1T2}{T1}$

= $$\frac{250\times60}{19}$

= 789.47 ≈ 789.5 ml.

So the new volume of the bag will be 789.5 mL.

Is table salt, NaCl, a typical ionic compound? Explain.

romanna [79]

Yes because Na is a metal and Cl is a nonmental, so they criss cross charges, as Na is 2+ and Cl is 2-, 2+ indicates that Na gives AWAY electrons to Cl and the 2- on Cl indicates it receiving electrons. NaCl is table salt and forms a crystal lattice structure, which is why salt is solid at room temperature.

sa solution is made by dissolving 26.42 g of (NH4)2SO4 in enough H2O to make 50.00 mL of solution. what is the molarity of the s

krok68 [10]

The answer is 0.2 M.

Molarity is a measure of the concentration of solute in a solution

c = n ÷V
c - concentration of solute,
n - number of moles of solute
V - volume of solution

We know:

V = 50.00 mL = 0.05 L

c = ?

n = ?

Let's calculate concentration:

c = m/(V * Mr)

The molar mass of (NH4)2SO4 is the sum of atomic masses (Ar) of its elements):
Mr ((NH4)2SO4) = 2Ar(N) + 8 Ar(H) + Ar(S) + 4Ar(O)
= 2 * 14 + 8 * 1 + 32 + 4 * 16 =
= 28 + 8 + 32 + 64 =
= 132 g/mol

c = 26.42 g/ (0.05 L * 132g /mol) =26.42 g/ 6.6 L*g/mol = 4 mol/L = 4 M

Now, calculate molarity:
c = n ÷V
n = c * V
n = 4 mol/L * 0.05 L
n = 0.2 mol
