Explanation:

it says it's correct...

The conversion of units of temperatures from one scale to the other which is measure by Carla and Maurice are given as.

298.34 K = 25.34°C

28.42°C = 301.42 K

The temperature can be measure by using three units.

Relationship between Kelvin (K) and Celsius (°C)

Let the value of temperature in Celsius (°C)  unit as X °C, then value of this temperature in  Kelvin (K) is,

X °C = 273 + X °C = (273 + X) K

Let the value of temperature in Kelvin (K) as Y K , then value of this temperature in Celsius (°C) is,

Y K =  Y K - 273 = (Y - 273) °C

If 298.34 K

Then 298.34 K = 298.34 K - 273 = 25.34°C

If 28.42°C

Then, 28.42°C =  273 + 28.42°C = 301.42 K

From the forgoing, we can conclude that the the correct statements are;

The redox reaction is one in which one specie is oxidized and the other is reduced. We can obtain the equilibrium constant from the relation;

E°cell = 0.0592/n log K

E°cell = cell potential

n = number of electrons

K = equilibrium constant

E°cell = -0.403 - 0.535 = -0.938 V

n = 2 electrons

Thus;

-0.938 =  0.0592/2 logK

-0.938 * 2/ 0.0592 = log K

Answer:

the answer

Answer:

Volume = 3.4 L

Explanation:

In order to calculate the volume of CO₂ produced when 15.2 g of CaCO₃ is heated, we need to first write out the balanced equation of the thermal decomposition of CaCO₃:

CaCO₃ (s) + [Heat] ⇒ CaO (s) + CO₂ (g)

Now, let's calculate the number of moles in 15.2 g CaCO₃:

mole no. = \(\mathrm{\frac{mass}{molar \ mass}}\)

                 = \(\frac{15.2}{40.1 + 12 + (16 \times 3)}\)

                 = 0.1518 moles

From the balanced equation above, we can see that the stoichiometric molar ratios of CaCO₃ and CO₂ are equal. Therefore, the number of moles of CO₂ produced is also 0.1518 moles.

Hence, from the formula for the number of moles of a gas, we can calculate the volume of  CO₂:

mole no. = \(\mathrm{\frac{Volume \ in \ L}{22.4}}\)

⇒ \(0.1518 = \mathrm{\frac{Volume}{22.4}}\)

⇒ Volume = 0.1518 × 22.4

                 = 3.4 L

Therefore, if 15.2 g of CaCO₃ is heated, 3.4 L of CO₂ is produced at STP.

The partial charges on each fluorine atom are negative. Option B) The central O atom is the correct answer. Option B

The partial charges in a molecule are determined by the electronegativity values of the atoms involved. Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. In the case of \(F_2O\), fluorine (F) is more electronegative than oxygen.

Fluorine is the most electronegative element on the periodic table, meaning it has a high ability to attract electrons. Oxygen is also relatively electronegative but less so than fluorine. When fluorine atoms bond with oxygen, the shared electrons will be pulled more towards the fluorine atoms, creating a polar covalent bond.

In \(F_2O\), each fluorine atom will pull the shared electrons towards itself, resulting in a higher electron density around the fluorine atoms. This creates a region of partial negative charge around the fluorine atoms.

Conversely, the oxygen atom will have a region of lower electron density and, therefore, a partial positive charge. This is because the shared electrons spend more time around the fluorine atoms due to their higher electronegativity.

Option B

The volume of hydrogen gas produced in the reaction of 73 grams of zinc and 73 grams of hydrochloric acid (under normal conditions) is approximately 22.4 liters.

To calculate the volume of hydrogen gas produced in the reaction of zinc and hydrochloric acid, we need to use the principles of stoichiometry and the ideal gas law.

First, let's write the balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl):

Zn + 2HCl →\(ZnCl_2\)+ H2

From the equation, we can see that one mole of zinc reacts with two moles of hydrochloric acid to produce one mole of hydrogen gas. To determine the number of moles of zinc and hydrochloric acid, we need to convert the given masses into moles.

The molar mass of zinc (Zn) is approximately 65.38 g/mol, so 73 grams of zinc is equal to:

73 g Zn * (1 mol Zn / 65.38 g Zn) ≈ 1.116 mol Zn

Similarly, the molar mass of hydrochloric acid (HCl) is approximately 36.46 g/mol, so 73 grams of HCl is equal to:

73 g HCl * (1 mol HCl / 36.46 g HCl) ≈ 2.002 mol HCl

According to the balanced equation, the reaction produces one mole of hydrogen gas for every two moles of hydrochloric acid. Therefore, since we have 2.002 moles of HCl, we expect to produce half that amount, or approximately 1.001 moles of hydrogen gas.

To calculate the volume of hydrogen gas, we can use the ideal gas law, which states:

PV = nRT

Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. In this case, we assume the reaction is conducted under normal conditions, which means a pressure of 1 atmosphere and a temperature of 273.15 Kelvin.

Rearranging the equation to solve for V, we have:

V = nRT / P

Substituting the values, we get:

V = (1.001 mol) * (0.0821 L·atm/(mol·K)) * (273.15 K) / (1 atm) ≈ 22.4 L

Therefore, the volume of hydrogen gas produced in the reaction is approximately 22.4 liters.

If 10.5 g of Ag and 7.5 g of S are reacted and 9.8 g of  \(Ag_2S\) is obtained, the percent yield of the reaction would be 81.4%

Ag and S react to form \(Ag_2S\) as follows:

\(2Ag + S -- > Ag_2S\)

The mole ratio of Ag to S is 2:1.

10.5 g of Ag = 10.5/108

                     = 0.0972 moles

7.5 g of S = 7.5/32

                = 0.2344 moles

In other words, Ag is limiting in availability.

The mole ratio of Ag to  \(Ag_2S\) = 2:1

0.0972 Ag is equivalent to 0.0972/2 = 0.0486 moles of  \(Ag_2S\)

0.0486 moles  \(Ag_2S\) weighs = 0.0486 x 247.8

                                              = 12.04 grams

percent yield of  \(Ag_2S\) = 9.8/12.04 x 100%

The molarity of the solution decreases on dilution by adding distilled water. The molarity of the solution of 17.51 ml ,  6 M HCl when added to 6.36 ml is 4.4 M.

Molarity is a common term used to express the concentration of a solution. The molarity of a solution is the ratio of the number of moles of solute to the volume solution in liter.

If a solution of volume V1 ml with M1 molarity is diluted to V2 ml of M2 molarity, then, the relation between the two concentrations is written as:

M1 V1 = M2 V2.

given, M1 = 6 M

V1 = 17.51

Answer:

1. If an organism has high biological fitness in one habitat, this does not mean it will have high fitness in another. This is because organisms adapt accordingly to their environment. Therefore, since there is variability among habitats, this does not guarantee that the organism will always have high biological fitness.

2. Natural selection produces changes in populations. Individual organisms are directly impacted by it, as it determines their survival rate, but the only genetic changes would occur in a population.

3. If there are no organisms with varying traits in a population, they will likely go extinct after a major environmental change. This is because natural selection will remove all organisms who are unable to survive in the new environment. If the population does not have the variability to survive this, then they will go extinct.

If an organism has a high biological fitness in one habitat, then it doesn't guarantee a high biological fitness in a different habitat; natural selection does change the individual. The population will go extinct if the individuals can't reproduce.

The individual that lives in an ecosystem can change itself due to natural selection, as natural selection favors the individuals who can survive in the changing environment, and the change in the environment induces the change in the organism. There is no reproductive success if the organisms are reproductively isolated within the population.

Hence, if an organism has a high biological fitness in one habitat, it doesn't guarantee a high biological fitness in a different habitat; natural selection does change the individual. The population will go extinct if the individuals can't reproduce.
