Calculate the molarity of the solution to 3 digits. 100. g of C12H22O11 (molecular weight = 342.28 g/mole) in 1.15 liters of solvent M

Answers

Answer:

0.254 M

Explanation:

The molarity is given by the formula M: Number of Moles/ Vol (L)

Number of Moles : 100 g/342.28 g/mol = 0.292 moles

M: 0.292 moles/ 1.15 L = 0.254 M to three significant figures

When a solution forms, what interactions between particles are involved? Which are exothermic? Which are endothermic? please explain

Answers

Answer:

Explanation:

There are three types of interactions involved between the particles when solution are formed.

1 : Solute - solute interaction:

2 : Solute - solvent interaction:

3 : Solvent - solvent interaction:

1 : Solute - solute interaction:

It is the inter-molecular attraction between the solute particles.

2 : Solute - solvent interaction:

It involve the inter-molecular attraction between solvent and solute particles.

3 : Solvent - solvent interaction:

It involve the intermolecular attraction between solvent particles.

Solutions are formed if the intermolecular attraction between solute particles are similar to the attraction between solvent particles.

Exothermic process:

The process will exothermic when solute solvent bonds are formed with the release of energy and energy required to brake the solute-solute particles and solvent solvent particles are less.

Endothermic process:

The process will be endothermic when energy required to break the solute-solute particles and solvent solvent particles are higher than energy released when solute solvent bonds are formed .

Final answer:

Solution formation involves three particle interactions: solute-solute, solvent-solvent, and solute-solvent interactions. Breaking solute-solute and solvent-solvent interactions requires energy, so these are endothermic processes. Solute-solvent interaction formation releases energy, making it an exothermic process.

Explanation:

When a solution forms, three main types of interactions between particles are involved: solute-solute interactions, solvent-solvent interactions, and solute-solvent interactions. The formation of a solution is essentially a sort of balance between these interactions.

Solute-solute interactions are the attractions between particles (atoms, molecules, or ions) within the solute. The breaking of these attractions is an endothermic process, as it requires energy to be put into the system to overcome these attractions.

Solvent-solvent interactions are the attractions between particles within the solvent. Like solute-solute interactions, the breaking of solvent-solvent interactions is also an endothermic process.

Solute-solvent interactions occur between particles of the solvent and solute when a solution is formed. This is the point at which the solvent 'dissolves' the solute. The formation of these new attractions releases energy, making it an exothermic process.

A lab technician needs to create 570.0 milliliters of a 2.00 M solution of magnesium chloride (MgCl2). To make this solution, how many grams of magnesium chloride does the technician need?Refer to the periodic table for help. Express your answer to three significant figures.

The required mass is grams.

Answers

This question needs to use the molarity equation, $M=(n)/(V)$ , where M is molarity, n is number of moles and V is the volume. With this equation we can find the number of moles. The volume of 570ml should be converted to L for correct units.

$n=MV= (2mol)/(L)* 570ml * (L)/(1000ml)= 1.14mol$

Multiply the number of moles by the molecular mass of $MgCl_2$ which is 95.21 g/mol to get the mass.

$1.14 mol Mg(Cl_2) *(95.21 g)/(mol) = 108 g$ .

PLEASE HELP!!!A vacuum flask keeps its contents warmer or cooler than the surrounding environment for a length of
time. It consists of two flasks, one inside the other, that connect at the neck. The space between the two
flasks is completely empty of air.

Q-Why does the design of the vacuum flask minimize heat transfer by conduction?

A)- One flask is smaller than the other flask.
B)- One flask is more reflective than the other flask.
C)- There is no air between the two flasks.
D)- The two flasks do not touch each other, except at the neck.

Answers

Answer is: C) There is no air between the two flasks.

Heat in this example can transfer throw thermal conduction.

Because there are no mo molecules to transfer heat, there is no conduction.

Thermal conduction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.

The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.

Because there are no mo molecules to transfer heat, there is no conduction.

C. Heat could easily travel through the molecules in the air and escape/enter the flask. Removing the air slows down the heat transfer.
