Answer:

The answer to your question is below

Explanation:

Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.

                    Kind of elements         Difference of electronegativity     Bond

a) MgO         Metal - Nonmetal                3.44 -  1.31 = 2.13                     Ionic

b) SrCl₂        Metal -Nonmetal                  3.16 - 0.95 = 2.21                    Ionic

c) O₃             Nonmetal- Nonmetal          3.44 - 3.44 = 0                      Covalent

d) CH₄O       Nonmetal-Nonmetal           3.44 - 2.55 = 0.89                Covalent

   Carbon, Hydrogen and oxygen are nonmetals

2) Silver coins can conduct electricity.

A sample of gas at 301 Kelvin and 1.5 atmospheres has a density of 3.90 g/L. What is the molar mass of this gas? Show all of the
meriva
PV = nRTP is pressure, V is volume in L, n is number of moles, R is the gas constant,and T is temperature in K

(1.5 atm)(1 L) = (n)(.08206)(301K)

n = .06 moles in one liter

If there are 3.9 grams in .06 moles then

1/.06 x 3.9 = 64.2 grams per mol

What is the molarity of a 250.0 milliliter aqueous solution of sodium hydroxide that contains 15.5 grams of solute
tensa zangetsu [6.8K]

There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. The concentration of the solution is calculated as follows:

 <span> </span><span>Molarity = 15.5 g NaOH (1 mol NaOH / 40 g NaOH)  / .250 L solution</span>

<span>Molarity = 1.55 M</span>

Which forces are intramolecular and which intermolecular?
AleksAgata [21]

Butter won't melt in a fridge because of intermolecular tensions. While the bonds inside of the fat molecules are unbroken, the attractions between the fat molecules are weaker.

What intermolecular forces are present in butter?

The intermolecular forces known as London dispersion forces are the weakest and are most prominent in hydrocarbons. Due to the fact that butter molecules are hydrocarbons, London dispersion forces do exist between them.

How do intermolecular forces affect melting?

More energy is required to stop the attraction between these molecules as the intermolecular forces become more powerful. Because of this, rising intermolecular forces are accompanied with rising melting points.

Which forces are intramolecular and which are intermolecular?

Intramolecular forces are those that hold atoms together within molecules. The forces that hold molecules together are known as intermolecular forces.
