Answer:

The answer to your question is

a) 212.7 g

b) 110 g

Explanation:

a) Mass of three moles of Chlorine

Atomic weight of Chlorine = 35.45 g but chlorine is a diatomic molecule then the atomic weight = 2(35.45) g = 70.9 g

70.9 g of Cl₂ --------------- 1 mol

x --------------- 3 moles

x = 3(70.9)/1

x = 212.7 g

b) mass of one mole of K₂S

Molecular mass = (39 x 2) + (32 x 1)

= 78 + 32

= 110 g

110 g of K₂S ---------------- 1 mol

Why would two poles of different magnets attract each other?

Kruka [31]

When two magnets are brought near each other, like poles repel; opposite poles attract. When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.

For each of the following choose the variable that will be more favorable in solution formation. A) Weak or Strong Solvent inter

Deffense [45]

Based on factors affecting solution formation;

Strong solvent-solute intermolecular forces favors solution formation.
Increase in entropy favours solution formation
Decrease in enthalpy favours solution formation

<h3>What is a solution?</h3>

A solution is a substance formed when a substance known as solute dissolves in another substance know as solvent.

Factors that affect solution formation include:

strength of intermolecular forces between solute and solvent
entropy
enthalpy

Strong solvent-solute intermolecular forces favors solution formation.

Increase in entropy favours solution formation

Decrease in enthalpy favours solution formation.

The American Heart Association recommends to eat no more than 2,301mg of sodium per day. Convert the mass of

castortr0y [4]

The mass of 2,301 grams of sodium in ounces is 0.0811757609 ounces.

The amount of sodium recommended by American heart association is 2301 mg. This limit should not be crossed in a day.

We have to convert Mass of sodium from mg to ounces.

We know,

1 ounce = 28.3459 grams.

We also know,

1 gram = 1000 milligrams.

So,

28.3459 grams = 28.3459 x 1000 milligrams.

28.3459 grams = 28345.9 milligrams.

1 ounce = 28345.9 mg.

1 mg = 1/28345.9 ounces

Weight of sodium 2301mg in ounces,

2301mg = 2301/28345.9 ounces

Dividing till last significant figure,

2301 mg = 0.0811757609 ounces.

Mass of sodium in ounces is 0.0811757609.

Despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided, you should be

navik [9.2K]

Answer:

G<0, spontanteous

H<0, from equation

S>0, gas to solid

Explanation:

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. Despite its name, silica gel is a solid. It is a chemically inert, highly porous, amorphous form of SiO2. Water vapor readily adsorbs onto the surface of silica gel, so it acts as a desiccant. Despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided, you should be able to make an educated guess about the thermodynamic characteristics of the process. Predict the signs of ΔG, ΔH, and ΔS.
