write three disadvantages of hard water.​

Answers

Answer 1

The three disadvantages of hard water are:

1. Hard water is unsuitable for washing because soap does not readily create a lather in it.

2. Soap may react and produce, wasting the soap.

3. Due to the development of calcium and magnesium carbonates, tea kettles will get furred.

Hard water

Water that contains a lot of minerals is referred to as hard water. In limestone, chalk, or gypsum deposits, which are mostly composed of calcium and magnesium carbonates, bicarbonates, and sulphates, hard water is created as a result of percolation. A moderate health advantage from drinking hard water is possible. In industrial settings where water hardness is regulated to prevent expensive breakdowns in boilers, cooling towers, and other water-handling equipment, it can present serious issues. Hard water is frequently detected in home settings by the build-up of lime scale in kettles and water heaters as well as by the absence of foam when soap is agitated in water. Wherever there is a worry about water hardness, water softening is frequently employed to lessen the negative impacts of hard water.

b) Suggest some reasons as to why this value is different to the one obtained in the practical. (What are the reasons that the the theoretical and actual enthalpy changes are different)

Answers

The Molar enthalpy of combustion of methanol obtained from the practical is -31.02 kJ/mol.

The molar enthalpy of combustion from bond energies, ΔH is -543 kJ/mol

The differences in the values could be due to:

Heat losses from the calorimeter to the surroundingsInaccurate measurements of mass and temperature changes

What is the enthalpy theoretical and actual enthalpy of combustion of methanol?

The actual enthalpy of combustion of methanol is calculated from the data obtained from the laboratory work.

The enthalpy of combustion is equal to the heat energy given off from the combustion of methanol.

Quantity of heat gained by water , q = -mcθ

where:

m = massc = specific heat capacityθ = temperature change

mass of water heated = 100 g

specific heat capacity of water = 4.18 J/g/°C

temperature change = 32.4°C - 21.5°C = 10.9°C

q = -(100 * 4.18 * 10.9) J

q = - 4556.2 J

moles of methanol reacted = mass/molar mass

mass of methanol = 80.6 - 75.9 = 4.7 g

molar mass of methanol = 32 g/mol

moles of methanol = 4.7/32 = 0.14687 moles

Molar enthalpy of combustion of methanol = -4556.2 J/0.14687 mole

Molar enthalpy of combustion of methanol = -31.02 kJ/mol

Calculating molar enthalpy of combustion from bond energies:

ΔH = sum of the bond energies of bonds broken - sum of the bond energies of the bonds formed

Sum of bond energies of bonds broken = (3 * 412) + 358 + 463 + (1.5 * 496) + 35 = 2836 kJ/mol

Sum of bond energies of bonds formed = (2 * 743) + 2(2 * 463) + 41 = 3379 kJ/mol

ΔH = 2836 kJ/mol - 3379 kJ/mol

ΔH = -543 kJ/mol

The value obtained from the practical is less than that from the bond energies

b. The possible reasons for the difference in value obtained from the practical is less than that from the bond energies include:

Heat losses from the calorimeter to the surroundingsInaccurate measurements of mass and temperature changes.

In conclusion, the molar enthalpy of combustion of methanol is negative since heat is given off during the reaction.

Determine which substance in the following pair has the greater tendency to be oxidized.

Li or K

Answers

Potassium (K) has the greater tendency to be oxidized when compared to Lithium (Li).

What is oxidation?

Oxidation is a chemical process triggered by the reaction between an compound and an oxidizing agent. The agent is what gains electrons and undergoes reduction, causing what is called oxidation.

With that being said, as you go down the alkali metal group, the ionisation energy decreases. The tendency of an atom to give its electron (or get oxidised) increases. Therefore, potassium oxidises more easily than lithium or in other words, potassium has a lesser tendency to get reduced compared to lithium.

As lithium has a higher tendency to get reduced than potassium, lithium gets deposited instead of potassium.

Calculate the vapor pressure of a solution of 32.5 g of glycerol (C3H8O3) in 500.0 g of water at 25°C. The vapor pressure of water at 25°C is 23.76 torr. (Assume ideal behavior.)

Answers

The vapor pressure is obtained as 23.47 torr.

What is the vapor pressure?

Given that; p = x1p°

p = vapor pressure of the solution

x1 = mole fraction of the solvent

p° = vapor pressure of the pure solvent

Δp = p°(1 - x1)

Δp =x2p°

Δp =  vapor pressure lowering

x2 = mole fraction of the  of the solute

Number of moles of  glycerol =  32.5 g/92 g/mol = 0.35 moles

Number of moles  of water = 500.0 g/18 g/mol = 27.8 moles

Total number of moles = 0.35 moles + 27.8 moles = 28.15 moles

Mole fraction of glycerol = 0.35 moles/28.15 moles = 0.012

Mole fraction of water = 27.8 moles/28.15 moles =0.99

Δp =  0.012 * 23.76 torr

Δp =  0.285 torr

p1 = p° - Δp

IUPAC rules for alkene nomenclatureThe parent alkene is chosen to have the longest carbon chain containing the carbon-carbon double bond.The alkane's suffix "ane" is changed to "ene." An alkene is referred to as a diene or triene depending on whether a double bond appears twice or three times in the parent chain.the location of side chains or double bonds denoted by the numbers 1, 2, 3, etc.The carbon atom in the double bond, which is written directly before the suffix "ene," receives the lowest number because it is the longest chain and is numbered from that end. If both sides of a double bond receive the same number as the chain is being numbered, the carbon chain is numbered so that the substituent receives the lowest number.

What is the [H3O+] if the [OH-] is 1 x 10 -11 ?

Answers

Taking into account the definition of pH and pOH, [H₃O⁺] will be 1×10⁻³ M.

Definition of pH

pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:

pH= - log [H⁺]= - log [H₃O⁺]

Definition of pOH

Similarly, pOH is a measure of hydroxyl ions in a solution and is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:

pOH= - log [OH⁻]

Relationship between pH and pOH

The following relationship can be established between pH and pOH:

pOH + pH= 14

Hydroxide ion concentration

In this case, you know that [OH⁻]= 1×10⁻¹¹ M.

Replacing in the definition of pOH, it is calculated as:

pOH= - log (1×10⁻¹¹ M)

Solving;

pOH= 11

Replacing in the relationship established between pH and pOH, the pH can be calculated as:

pH + 11= 14

Solving:

pH= 14 - 11

pOH= 3

Replacing in the definition of pH the concentration of H₃O⁺ ions is obtained:

- log [H₃O⁺]= 3

Solving:

[H₃O⁺]= 10⁻³

[H₃O⁺]= 1×10⁻³ M

In summary, [H₃O⁺] will be 1×10⁻³ M.

Answers

Answer:

0.15 M KCl

Explanation:

(Step 1)

Convert the original volume from mL to L. Calculate the moles of the original solution.

75.0 mL / 1,000 = 0.0750 L

Molarity = moles / volume (L)

0.200 M = moles / 0.0750 L

0.0150 = moles

(Step 2)

Convert the final volume from mL to L. Calculate the final molarity.

100. mL / 1,000 = 0.100 L

Molarity = moles / volume (L)

Molarity = 0.0150 moles / 0.100 L

Taking into account the definition of calorimetry and latent heat, the heat needed to melt 100.0 grams of ice that is already at 0°C is 33,400 J (option A).

Calorimetry

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Latent heat

Latent heat is defined as the energy required by a quantity of substance to change state.

When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.

In this case, the heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to

Q = m×L

where L is called the latent heat of the substance and depends on the type of phase change.

Heat needed to melt ice

In this case, you have to melt the ice into liquid water.Being the specific heat of melting of ice is 334 J/g, the heat needed to melt 100 grams of ice is calculated as:

Q= 100 grams× 334 J/g

The picture shows two containers filled with a gas.

Two equally sized containers are shown with tight lids and each container has a thermometer. The container on the left is labeled A and the one on the right is labeled B. The thermometer inside container B shows a higher temperature than the thermometer inside container A.

Which statement is correct?

Answers

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

What is temperature?

The term temperature refers to a measure of the average kinetic energy of the molecules of  body. This means that molecules that are at high temperature tend to move faster than the molecules that are at low temperature.

As such, the higher temperature of the molecules of the gas in B shows that the molecules in B are faster than those in A thus the correct statement is; "the average kinetic energy of the gas particles is greater in container B because it has a higher temperature."
