what is a saturted solution

Answers

Answer:

Please find the definition and further explanation below

Explanation:

Based on the ability for the solvent (liquid substance) to dissolve a solute (solid substance), a solution can either be unsaturated, saturated or supersaturated. A SATURATED SOLUTION is that which contains the maximum amount of solute a solvent can possibly dissolve.

In other words, a saturated solution can no longer dissolve anymore solute, and hence, any further solute added forms crystals or makes the solution supersaturated.

what is the difference between physical chemistry and environmental chemistry.
please Answer and give the correct answer...

Answers

Answer:

Physical chemistry is the study of macroscopic, and particulate phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibrium while environmental chemistry is the study of chemical processes that occur in water, air, terrestrial and living environments, and the effects of human activity on them. 

Physical chemistry is the area of chemistry that deals with how materials interact and change. The scientific study of chemical and biological phenomena that take place in the environment is known as environmental chemistry.

Physical chemistry attempts to quantify, correlate, and explain the quantitative features of reactions by focusing, in contrast to other branches, on the physics principles that underlie all chemical interactions (such as the gas laws).

While environmental chemistry is the study of chemical species' sources, reactions, movement, impacts, and fates in the air, soil, and water environments, as well as the impact of human activity and biological activity on these, can be summed up as the field of chemical ecology.

How do you think you results would be affected if using K2Cr2O7/H2SO4 as the oxidizing agent instead of KMnO4

Answers

Answer:

Due to weak oxidizing agent.

Explanation:

In my opinion the results would be affected if using K2Cr2O7/H2SO4 as the oxidizing agent instead of KMnO4 because K2Cr2O7/H2SO4 is weak oxidizing agent as compared to KMnO4. An oxidizing agent is a substance that has the ability to oxidize other substances means that accept their electrons so that's why the results of strong oxidizing agent is different than weak oxidizing agent.

The results of the reaction will be affected due to the difference in :

Oxidizing agent strength

The use of  K₂Cr₂O7 / H₂SO₄ which is weaker oxidizing agent in the reaction will produce a different result from the use of KmnO₄ which is a stronger oxidizing agent.

This is because stronger oxidizing agents in reaction readily accept electrons from reactants while weaker oxidizing agents do not readily accept electrons from substances reacting in the reaction.

Therefore we can conclude that The results of the reaction will be affected due to the difference in oxidizing agent strength

an experiment was carried out and H2SO4 was collected resulting in a 92.0% yield. What mass of H2SO4 was collected from the experiment?

Answers

Answer:

The mass of H2SO4 collected is 92.0g assuming the theoretical yield of H2SO4 is 100g

Explanation:

Assuming the theoretical yield of the sulfuric acid, H2SO4, is 100g.

To solve this question we must use the equation of percent yield:

Percent yield = Actual yield / Theoretical yield * 100

Where percent yield = 92.0%, actual yield is the mass of H2SO4 produced and theoretical yield is 100g, the mass we are assuming

Replacing:

92.0% = Actual yield / 100g * 100

92.0g = Actual Yield

The mass of H2SO4 collected is 92.0g assuming the theoretical yield of H2SO4 is 100g

How many grams of Br are in 345g of CaBr2?

Answers

Answer:

276g of Br are present

Explanation:

To solve this question we need to find the moles of CaBr2 using its molar mass -CaBr2: 199.89g/mol-. As 1 mole of CaBr2 contains 2 moles of Br we can find the moles of Br and its mass:

Moles CaBr2:

345g * (1mol/199.89g) = 1.7259 moles CaBr2

Moles Br:

1.7259 moles CaBr2 * (2mol Br / 1mol CaBr2) = 3.4519 moles Br

Mass Br -Molar mass: 79.904g/mol-

3.4519 moles Br * (79.904g/mol) = 276g of Br are present

Answers

Using the idea of the  molar volume of butane gas, we have 2.23 moles of water vapor.

What is a reaction equation?

The term reaction equation shows the conversion of reactants to products. First of all, we must get down the reaction equation as follows;

C4H10(g) + 13/2O2(g) ----> 4CO2 (g) + 5H2O(g)

From the balanced reaction equation;

1 mole of  butane gas yields 5 moles of water vapor. Since 1 mole of butane gas occupies 22.4 L. Hence;

22.4 L of butane yields 5 moles of water vapor

10 L of butane gas yields 10 L * 5 moles/22.4 L = 2.23 moles

describe the formation of covalent bond in methane (5 marks) ​

Answers

Answer: Covalent bonding is when atoms of different elements  share electrons

Explanation: Taking Methane CH₄

it contains Hydrogen and Carbon atoms pairing electrons. the electronic configuration for carbon is 2,4 that is to say it has 4 electrons in its valence shell (outer shell) and hydrogen has 1 so carbon shares its four electrons with four hydrogen atoms thus forming a covalent bond. so they now have a stable arrangement of electrons in their outer shell ,thus giving CH₄

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, sharing of electron is the only basis for the formation of covalent bond in methane.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

Carbon has an electrical configuration of 2,4. Hydrogen only has one electron in its valence shell, whereas carbon contains four electrons. In order to create methane, carbon forms a covalent connection with four hydrogen atoms, sharing its four electrons with them.

Therefore, sharing of electron is the only basis for the formation of covalent bond in methane.

Si 40 g de un compuesto C6H10O5 se disuelven en 500 g de agua, determine el punto de ebullición de esta solución. (Agua: temperatura de ebullición 100 °C y Ke = 0,52 °C/m)

Answers

The question is: If 40 g of a compound C6H10O5 are dissolved in 500 g of water, determine the boiling point of this solution. (Water: boiling temperature 100 ° C and Kb = 0.52 ° C / m).

Answer: The boiling point of given solution is [tex]100.256^{o}C[/tex].

Explanation:

Given: Mass of solute = 40 g

Mass of solvent = 500 g (1 g = 0.001 kg) = 0.5 kg

[tex]K_{b} = 0.52^{o}C/m[/tex]

Molality is the moles of solute present in kg of solvent.

Moles is the mass of substance divided by its molar mass. Hence, moles of [tex]C_{6}H_{10}O_{5}[/tex] (molar mass = 162.141 g/mol) is calculated as follows.

[tex]Moles = \frac{mass}{molar mass}\\= \frac{40 g}{162.141 g/mol}\\= 0.246 mol[/tex]

Now, molality of the solution is calculated as follows.

[tex]Molality = \frac{molesof solute}{mass(in kg)}\\= \frac{0.246}{0.5 kg}\\= 0.492 m[/tex]

The boiling point is calculated as follows.

[tex]\Delta T_{b} = K_{b}m[/tex]

where,

m = molality

Substitute the values into above formula as follows.

[tex]\Delta T_{b} = K_{b}m\\= 0.52^{o}C/m \times 0.492 m\\= 0.256^{o}C[/tex]

As the boiling point of water is 100 degree Celsius. So, the boiling point of solution is as follows.

[tex](100 + 0.256)^{o}C\\= 100.256^{o}C[/tex]

Thus, we can conclude that the boiling point of given solution is [tex]100.256^{o}C[/tex].

What are two factors that determine the concentration of hydronium (or hydroxide) ions in an acid (or base) solution?

Answers

Answer:

hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes, and specific vocabulary has been developed to describe these concentrations in relative terms. A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.
