What happens when a solute dissolves in water?

Answer:
Dissociate

Answers

Answer 1

When a solute dissolves in water, a solution is formed.

What is a solute?

A solute is any substance capable of dissolving in a solvent in order to form a solution.

When a solute dissolves in a particular solvent, it is said to be that solvent-soluble. Otherwise, it is insoluble.

Now, when the solvent in question is water, the substance is said to be water-soluble or water-insoluble as the case may be.

If a solute is water-soluble, then it forms a solution. If the solute is ionic, it does not just form a solution, it dissociates into its component ions in the solution.

If the solute is not ionic, no dissociation occurs in the solution.

The maximum amount of ethane (C₂H₆ ) that can be formed is 9.15 gThe formula of the limiting reagent, hydrogen is H₂.The amount of the excess reagent that remains after the reaction is complete = 3.78 grams

What are limiting reagents?

Limiting reagents refers to the reactants in a given reaction which is completely used up at the end of a reaction.

Once the limiting reagent is used up, the reaction will stop.

Considering the given question and the data provided:

0.610 grams of hydrogen gas are allowed to react with 12.4 grams of ethylene (C₂H₄).

The equation of the reaction is as follows:

H₂ (g) + C₂H₄ (g) ---> C₂H₆ (g)

The mole ratio of the reactants is used to determine the limiting reactant.

Mole ratio of hydrogen to ethylene is 1 : 1

Moles of hydrogen = 0.610/2 = 0.305 moles

Moles of ethylene = 12.4/28 = 0.44 moles

The limiting reagent is hydrogen while the excess reagent is ethylene.

The maximum amount of ethane (C₂H₆ ) that can be formed is 0.305 moles.

mass of 0.305 moles of ethane = 0.305 * 30 grams

mass of 0.305 moles of ethane = 9.15 g

The moles of the excess reagent that remains after the reaction is complete = 0.44 - 0.305 = 0.135 moles

Concentrated nitric acid, HNO3, is 16.0 mol dm–3. What volume would you need to prepare 100 cm3 of 0.50 mol dm–3 HNO3?

Answers

The question requires us to calculate the volume of concentrated HNO3 solution (concentration = 16.0 mol/dm^3) to prepare 100 cm^3 of a 0.50 mol/dm^3 HNO3 solution.

We need to calculate the volume necessary from a concentrated solution to prepare a more dilluted solution. The number of moles of HNO3 in the solutions will not change, thus we can say:

[tex]n_1=n_2[/tex]

where n is the number of moles of HNO3 and 1 and 2 refers to the initial solution and final solution, respectively.

The number of moles in a solution can be calculated as it follows:

[tex]C=\frac{n}{V}\to n=C\times V[/tex]

where C is the concentration and V is the volume of the solution.

We can combine these two equations to have the following expression:

[tex]n_1=n_2\to C_1\times V_1=C_2\times V_2[/tex]

With this expression, we can use the values given by the question to calculated the volume of the concentrated solution (V1) necessary to prepare a more dilluted solution:

[tex]\begin{gathered} C_1\times V_1=C_2\times V_2\to(16.0\frac{mol}{dm^3})\times V_1=(0.50\frac{mol}{dm^3})\times(100cm^3) \\ V_1=\frac{(0.50\text{ mol/dm}^3)\times(100cm^3)}{(16.0\text{ mol/dm}^3)}=3.12cm^3 \end{gathered}[/tex]

Therefore, the volume necessary of concentrated HNO3 to prepare 100 cm^3 of 0.50 mol/dm^3 HNO3 solution is 3.12 cm^3.

Density is the mass of a substance per unit volume. So, adding 9.628 ml of Ag to 51ml of H2O, makes the total volume 60.628ml.

What is meant by density ?

Density is the mass of a substance per unit volume. The most commonly used symbol for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: [tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex] where ρ is density, m is mass and V is the volume.

Density is an important concept because it allows us to determine which substances  float and which sink when placed in a liquid. In general, substances float until their density is lower than the density of the liquid in which they are placed.

Density = Mass/ water displaced

water displaced = Mass/Density

water displaced = 101 / 10.49

water displaced = 9.628 cm³

Answers

The negative sign indicators that the reaction is exothermic. the enthalpy change -2257.2 J.

Describe enthalpy.

Enthalpy, one of a thermodynamic system's attributes, is determined by multiplying the system's internal energy by the sum of its pressure and volume. The large surrounding environment conveniently offers this state function, which is commonly utilized in measurements of chemical, biological, and physical systems at constant pressure.

In order to calculate the system's physical dimensions, the pressure-volume term specifies the effort required to displace the system's surrounds and make room for it. The pressure-volume term is quite tiny for solids and liquids under ordinary conditions, but only fairly modest for gases. Enthalpy therefore acts as a substitute for energy in chemical systems.

The equation for the reaction is NaOH + HCl [tex]\rightarrow[/tex] NaCl + H₂O

Volume of the solution (100+100) ml = 200ml

Mass of solution = 200ml soln. x 1.00gm/1ml soln. (water density 1g/ml)

                           = 200ml

We, know the rule q=mcp∆t can be used to calculate the enthalpy change
Where q = enthalpy change
m = mass of solution
c = Specific heat of solution
∆t = Change in temperature

∴ m = 200gm soln.
c = 4.18J/g°C (water specific heat)
∆t = (27.2°C - 24.5°C)

q=mcp∆t
= 200gm x 4.18J/g°C x (27.2°C - 24.5°C)
= 2257.2 J

We known that
q reaction = - q solution
                 = (c x m x ∆t) soltuion
∴ q reaction = -2257.2 J

Therefore, the correct answer is -2257.2 J

Answers

There's no increase in the kinetic energies of the particles, and hence no rise in temperature, because the energy required for phase shifts is employed to break bonds.

Briefing :

If the pressure around a solid, liquid, or gas stays constant throughout a phase shift, the temperature will not change. In other words, once a liquid hits its boiling point, the temperature won't rise any further until the entire volume of the liquid has transformed into a gas.

How temperature and energy during a phase change are correlated?

As a solid transforms into a liquid during a phase change, its temperature stays constant because the heat energy is converted to potential energy. Similarly, when heat is supplied to a liquid, the temperature rises as the molecules once more move more quickly.

The volume of a rectangular prism = l × b × h

Where “b” is the base length “l” is the base width and “h” is the height of the rectangular prism.

If the nuclear reactor is made from a rectangular sheet then we can consider the metal sheet as a rectangular prism.

The Homer's volume of metal sheet =  2.6m × 4.4m × 3.0m = 34.32 m³

The Bart's volume of metal sheet =   2.65m × 4.38m × 3.05m = 35.40 m³

The difference between Bart's volume and  Homer's volume is :

If 9.60 g of CuSO4 are left after heating 15.01 g of the blue compound, calculate the number of moles of water originally
present in the compound.

Answers

Number of moles of water originally present in the compound is 0.060 mol

Mole is the SI unit of amount of substance of a specified elementary entity

Here given reaction is

CuSO₄ ⋅ 5H₂O → CuSO₄ + 5H₂O

And given data is  CuSO₄ =  9.60 g

So we have to find number of mole of water originally present in the compound = ?

So number of mole = mass of substance/mass of one mole

Number of mole = 9.60 g/159.6

Number of mole = 0.060 mol

Water originally present in the compound is 0.060 mol
