Describe the three steps of solution formation. be sure to include the details regarding the dissolving of the substance

Chemistry

Elza [17]3 years ago

The three steps involve;

Step 1: Separation/expansion of the solute particles

Step 2: Separation/expansion of the solvent particles

Step 3; Combining the solute and solvent particles


The first two steps are usually endothermic. Step 3, nonetheless, can be either exothermic or endothermic and is significant in determining whether the dissolving process will be endothermic or exothermic.

Answer:

The dissolution process is carried out in three completely independent stages:

1. Separation of solvent molecules

2. Separation of solute molecules.

3. Mixture of solvent and solute molecules.

Explanation:

A solution occurs when the solute and solvent molecules meet by intermolecular attractions, which should not be interpreted as chemical bonds. When a substance dissolves in another substance, the solute particles spread over the solvent. These particles break into positions occupied by solvent molecules. Its ease of replacement is dependent on the strength of three interactions: between solvent and solvent, between solute and solute, and between solvent and solute.

The correct description for an atom of helium would be option C. An atom of helium has its valence electrons in its first energy level, it wouldn't and can't satisfy the Octet rule as it only has 2 electrons, but with 2, it has a full shell, as the first energy level can hold only 2 electrons.

What is the temperature of 4.5 moles of a gas that occupies 50. mL at 1.35 atm?
devlian [24]

Answer:

T = 0.182 Kelvin

Explanation:

As we know that

PV = nRT\\

Where P is the pressure in atmospheric pressure

T is the temperature in Kelvin  

R is the gas constant  

V is the volume in liters

R = 0.08206

Substituting the given values in above equation, we get -

1.35 * \frac{50}{1000}= 4.5 * 0.08206* T\\

On rearranging, we get

T = \frac{1.35*50}{1000*0.08206*4.5} \\

T = 0.182 Kelvin

A student has a 2.123 g sample of a hydrated salt. she heats it to drive off all the water. after heating to constant mass, the
morpeh [17]
The mass of hydrated salt - 2.123 g
mass of anhydrous salt - 1.861 g
mass that has been reduced is the mass of water that has been heated and lost from the compound thereby making the salt anhydrous.
therefore mass of water lost - 2.123 - 1.861 = 0.262 g
number of moles of water lost - 0.262 g / 18 g/mol = 0.0146 mol 
number of moles of salt - 1.861 g / 380.6 g/mol = 0.00490 mol 
molar ratio of moles of water to moles of salt 
molar ratio = 0.146 mol / 0.00490 mol = 2.98 rounded off to 3
for every 1 mol of salt there are 3 moles of water
therefore empirical formula - Cu₃(PO₄)₂.3H₂O

How many ml of a 2.0 m nabr solution are needed to make 200.0 ml of 0.50 m nabr?
gogolik [260]

To solve this we use the equation,

 

<span> M1V1 = M2V2</span>

 

<span> where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.</span>

 

<span>2.0 M x V1 = 0.50 M x 200 mL</span>

<span>V1 = 50 mL needed</span>
