A solution is a homogeneous mixture of a solute and a solvent. Both can be solid, liquid, or gas. Solutions exist for every possible phase of the solute and the solvent.

A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. Remember, solutions are homogeneous mixtures.

You can find many solutions in your daily life.

For example, solutions are salt and water, rubbing alcohol, and sugar dissolved in water.

Let's take salt and water.

Solute here is the salt and the water is the solvent. The amount of solvent is higher than solute in a solution.

When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. That is why the mixture of salt and water is a solution.

Explanation:

Direct Relationship - a mathematical relationship between two physical variables that depend upon one another such that when one variable increases the related variable also increases.

Example - For an enclosed gas it is observed that an increase in temperature (T) also results in an increase in pressure (P). Such is represented as P ∝ T which reads pressure (P) is directly related (or, proportional) to temperature (T). This does not mean that the variables temperature and pressure are equal, only that when one increases or decreases the other variable also increases or decreases proportionally.

Problems in Gas Laws relating pressure and temperature is typically referred to as The Gay-Lussac Law. Empirically it is represented by  T₁/P₁ = T₂/P₂. Assume problem is given an enclosed gas at 25⁰C(= 298K*) and 750mm pressure. What is the pressure (P₂) if the temperature is increased to 35⁰C(= 308K)? and to 45⁰C(= 318K)?

*(Note: Problems in the empirical gas laws need to be worked in degrees Kelvin.)

T₁ = 25⁰C = 298K; P₁ = 750mm

T₂ = 35⁰C = 308K; P₂ =   ?

T₃ = 45⁰C = 318K; P₃ =  ?

T₁/P₁ = T₂/P₂ => P₂ = T₂·P₁/T₁ = 308K x 750mm / 298K = 775.17mm Pressure.

For P₃ calculation, one can work from either T₁,P₁ data or T₂,P₂ data.

This calculation chooses T₁,P₁ data.

T₁/P₁ = T₃/P₃ => P₃ = T₃·P₁/T₁ = 318K x 750mm / 298K = 800.34mm Pressure.

You apply T₂/P₂ = T₃/P₃ and you will find the same results for pressure.

Note that increasing temperature results in increasing pressure. This is 'direct relationship' analysis.

Dependent Variable & Independent Variable - The 'Dependent Variable' in a mathematical relationship  'Depends' upon an 'Independent Variable' which is chosen by the observer in order to determine the Dependent Variable. In the above problem, P is the dependent variable and T is the independent variable or, the variable the observer chooses to apply to the problem. Increases in Temperature (T) are chosen by observer to determine the Pressure (P). Increasing temperature (independent variable)  results in increasing pressure (dependent variable).

Inverse Relationship - a mathematical relationship between two physical variables that depend upon one another such that when one variable increases the related variable decreases.

Example: A gas confined in a cylinder with a movable piston starting at Volume-1 (V₁) and at Pressure-1 (P₁) is changed to Volume-2 (V₂)  will show a pressure value opposite to the direction of change (increased or decreased) to that of the volume change.

Problems in Gas Laws relating pressure and volume are typically referred to as Boyles Law problems. Empirically it is represented by  V₁·P₁ = V₂·P₂. Assume problem is given an enclosed gas at 255ml and 750mm pressure. What is the pressure (P₂) if the volume is increased to 425ml? (Similar to pulling the plunger out of a syringe to increase volume.)

V₁ = 255ml; P₁ = 750mm

V₂ = 425ml; P₂ =   ?

Using the Boyles Law relationship P₁V₁ = P₂V₂ => P₂ =  P₁V₁ /V₂

P₂ = (750mm)(255ml)/(425ml) = 450mm

Note P₂ has a decreased pressure value which is opposite in direction to the change in the independent variable, volume-2 (V₂). That is, an increase in volume (V) resulted in a decrease in pressure (P).

Cyclic Change - Change that is repetitive or repeats within a noted (given) time interval. Weather change is cyclic in that fall => winter => spring => summer => fall => winter => etc.  

Dynamic Equilibrium - In order to understand 'Dynamic Equilibrium' one must also define 'Static Equilibrium'. Static Equilibrium is when an object is not moving such as a marble sitting undisturbed on a level surface. All forces up, down, left & right are all equal. Dynamic Equilibrium is when an object is in motion at a constant speed on a level surface. All forces are also balanced forward, reverse, up & down. The term Dynamic Equilibrium is also applied to chemical reactions which means the rate of production of product is equal to the rate of production of reactant. This is typically represented by the equation  Reactants ⇄ Products. the double arrow indicates a steady state condition of dynamic equilibrium.

Q = Ksp = 1 × 10^(-12).

Substituting the values into the Nernst equation, we have:

0.799 V = E° - (RT/2F) * ln(1 × 10^(-12))

Now, solving for E°:

E° = 0.799 V + (RT/2F) * ln(1 × 10^(-12))

The value of R is the ideal gas constant, T is the temperature in Kelvin, and F is the Faraday constant.

To find the standard reduction potential at 25°C for the half-reaction Ag2CrO4(s) + 2e¯ → 2Ag(s) + CrO4²-(aq), we can use the Nernst equation, which relates the standard reduction potential (E°) to the equilibrium constant (K) and the reaction quotient (Q).

The Nernst equation is given as follows:

E = E° - (RT/nF) * ln(Q)

Given information:

Ksp = 1 × 10^(-12)

E = +0.799 V (standard reduction potential of Ag+ to Ag)

Since the reaction involves the dissolution of Ag2CrO4(s), the reaction quotient Q can be expressed as [Ag+]²/[CrO4²-].

Since the stoichiometry of the reaction is 2:1 for Ag2CrO4 to Ag+, we can say that [Ag+]² = Ksp.

Therefore, Q = Ksp = 1 × 10^(-12).

Substituting the values into the Nernst equation, we have:

0.799 V = E° - (RT/2F) * ln(1 × 10^(-12))

Now, solving for E°:

E° = 0.799 V + (RT/2F) * ln(1 × 10^(-12))

The value of R is the ideal gas constant, T is the temperature in Kelvin, and F is the Faraday constant.

Please note that without specific values for temperature (T) and the ideal gas constant (R), the exact standard reduction potential at 25°C cannot be determined.

3. Heat always flow from a warmer object to a cooler object.

4. The best description of convection is Heat transfer through movement in fluids.

Differential heating leads to convection currents. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.

The transfer of heat between two bodies by currents of moving gas or fluid is known as convective heat transfer. In free convection, air or water rises and is replaced by a cooler parcel of air or water as it moves away from the hot body.

Heat energy will always transfer from the warmer object to the cooler object under normal circumstances and in nature. Up until the two substances reach the same temperature, heat energy will transfer between them. The term "thermal equilibrium" describes this.

Given:

Mass of O₂   = 19.2g

Unknown:

Amount of iron used  =?

Solution:

To solve this problem, we adopt the mole concept.

   Since we know the mass of O₂;

         Number of moles  = \(\frac{mass}{molar mass}\)  

 Molar mass of  O₂ = 2(16)  = 32g/mol

           Number of moles = \(\frac{19.2}{32}\)   = 0.6moles

From the balanced reaction equation;

           4 moles of Fe will react with 3 moles of O₂

          0.6moles of O₂ will react with \(\frac{0.6 x 4}{3}\)   = 0.8mole of Fe

Mass of Fe  = number of moles x molar mass

Trust me I just took the test

There are approximately 6.022 × 10^23 atoms in 12 grams of Carbon-12 (12C).

The number of atoms in a given amount of a substance can be calculated using Avogadro's number, which represents the number of atoms or molecules in one mole of a substance. Avogadro's number is approximately 6.022 × 10^23.

Carbon-12 is a specific isotope of carbon, with an atomic mass of 12 atomic mass units (amu). One mole of Carbon-12 has a mass of 12 grams. Since one mole of any substance contains Avogadro's number of particles, in the case of Carbon-12, it contains 6.022 × 10^23 atoms.

Therefore, if we have 12 grams of Carbon-12, which is equal to one mole, we can conclude that there are approximately 6.022 × 10^23 atoms in this amount of Carbon-12.

In summary, 12 grams of Carbon-12 contains approximately 6.022 × 10^23 atoms. Avogadro's number allows us to relate the mass of a substance to the number of atoms or molecules it contains, providing a fundamental concept in chemistry and enabling us to quantify and understand the microscopic world of atoms and molecules.
