Answer:

Form: Chemical Potential Energy

Type: Non-renewable energy

Explanation:

Since there are no given options I am going to say fossil fuels are chemical Potential Energy because energy is stored in them until we extract them.

Fossil fuels are also considered non-renewable energy since eventually we will run out of them.

If you have either chemical Potential Energy or non-renewable energy as options either should be correct.

The current passing through the electrolytic cell is approximately 2.02 x 10^4 Amperes.

To calculate the current in amperes, we need to use Faraday's laws of electrolysis and the stoichiometry of the reaction.

Faraday's laws state that the amount of substance produced or consumed during electrolysis is directly proportional to the quantity of electricity passed through the cell. The relationship is given by:

Q = nF

Where Q is the electric charge in coulombs (C), n is the number of moles of substance involved in the reaction, and F is Faraday's constant, which is equal to 96,485 C/mol.

In this case, the substance being produced is Cl2, and we know the mass of Cl2 produced, which is 4.8 x 10^5 g.

First, we need to calculate the number of moles of Cl2 produced:

Molar mass of Cl2 = 35.45 g/mol

Moles of Cl2 = mass / molar mass = (4.8 x 10^5 g) / (35.45 g/mol) ≈ 1.354 x 10^4 mol

Now we can calculate the quantity of electricity passed through the cell using Faraday's laws:

Q = nF

Q = (\(1.354 x 10^4\)mol) * (96,485 C/mol)

Q ≈ 1.308 x 10^9 C

The quantity of electricity is given in coulombs. To find the current, we need to divide this value by the time in seconds.

Given that the time is 18 hours, we convert it to seconds:

Time = 18 hours * 60 minutes/hour * 60 seconds/minute

Time = 6.48 x 10^4 seconds

Finally, we can calculate the current:

Current (I) = Q / Time

I = (1.308 x 10^9 C) / (6.48 x 10^4 s)

I ≈ 2.02 x 10^4 Amperes

Therefore, the current passing through the electrolytic cell is approximately 2.02 x 10^4 Amperes.

Explanation:

Mol of NaI = 0.405 mol

Molarity of solution = 0.724 M

Molarity is given by

\(M=\dfrac{\text{mol}}{\text{Volume of solution in }NaI}\\\Rightarrow \text{Volume of solution in }NaI=\dfrac{0.405}{0.724}\\\Rightarrow \text{Volume of solution in }NaI=0.5594\ \text{L}\)

The required volume is \(0.5594\ \text{L}\).

The accurate responses are;

1) it has the configuration of of the noble gas in the same period

2) higher, gain, more

The electron configuration shows the arrangement of the atoms in an element. We know that in an element, the nucleus is at the core of the atom. The shells have energies increasing order with the shells that are close to the nucleus having the lowest energy and the energy of the shells tends to increase radially outwards from the nucleus.

Now let us try to look at sodium. We know that the formation of ions leads an element to attain the noble gas configuration. We can see that when sodium loses an electron, it closely resembles the noble gas neon.

The ionization energy is the energy that is required for the removal of one electron from the outermost shell of the atom. The complete statement therefore is; Ionization energies for nonmetals are higher than metals because they would rather gain  electrons than lose electrons, so it takes more energy.

Answer:

hydrochloric acid

Explanation:

If the hydrochloric acid used on cuts and scrapes for sanitation were to be very high in concentration. It would still kill bacteria it would just also start to burn through your skin.

Answer:

About 5.64 mol/L.

Explanation:

Recall that the concentration of a soluion, or its molarity, is given by:

\(\displaystyle \text{M} = \frac{\text{ mols solute}}{\text{ L soln.}}\)

In this case, our solute is 82.2 g of NaCl and our solution is in a 250. mL volumetric flask.

Convert 82.2 g of NaCl to moles of NaCl. The molecular weight of NaCl is:

\(\displaystyle \begin{aligned} \mathcal{M}_{\text{NaCl}} & = (22.99 + 35.45) \text{ g/mol} \\ \\ & = 58.44 \text{ g/mol}\end{aligned}\)

Hence:

\(\displaystyle 82.2\text{ g NaCl} \cdot \frac{ 1 \text{ mol NaCl}}{58.44 \text{ g NaCl}} = 1.41 \text{ mol NaCl}\)

Convert the volume to liters:

\(\displaystyle 250. \text{ mL} \cdot \frac{1 \text{ L}}{1000 \text{ mL}} = 0.250 \text{ L}\)

Hence, the concentration of the solution is:

\(\displaystyle \begin{aligned} \text{M} & = \frac{(1.41 \text{ mol NaCl})}{(0.250 \text{ L soln.})} \\ \\ & =5.64 \text{ mol/L} \end{aligned}\)

In conclusion, the concentration of the solution in mol/L is about 5.64 mol/L.

Answer:

The [H⁺] for this soluton is 2*10⁻³ M

Explanation:

pH, short for Hydrogen Potential and pOH, or OH potential, are parameters used to measure the degree of acidity or alkalinity of substances.

The values ​​that compose them vary from 0 to 14 and the pH value can be directly related to that of pOH by means of:

pH + pOH= 14

In this case, pOH=11.30, so

pH + 11.30= 14

Solving:

pH= 14 - 11.30

pH= 2.7

Mathematically the pH is the negative logarithm of the molar concentration of the hydrogen or proton ions (H⁺) or hydronium ions (H₃O):

´pH= - log [H⁺] = -log [H₃O]

Being pH=2.7:

2.7= - log [H⁺]

[H⁺]= 10⁻² ⁷

[H⁺]=1.995*10⁻³ M≅ 2*10⁻³ M

The [H⁺] for this soluton is 2*10⁻³ M

The pH of the NaOH solution has been 2.7. The hydrogen ion concentration of the NaOH solution has been 1.9 \(\rm \bold{\times\;10^-^3}\) M.

The pH of the solution has been used for the determination of the Hydrogen ion concentration in the solution. The higher the hydrogen ion concentration, the pH will tend to be more towards the lower side.

The pOH has been the hydroxide ion concentration in the solution, The higher the hydroxide ion concentration, the more pH will move towards the higher range.

The sum of pH and pOH has been the constant quantity.

pH + pOH = 14

The given NaOH solution has pOH 11.30. The pH of the solution will be:

pH + 11.30 = 14

pH = 14 - 11.30

pH = 2.7.

The pH of the NaOH solution has been 2.7.

pH can be defined as the negative log of the hydrogen ion concentration.

pH = -log [\(\rm H^+\)]

2.7 = log [\(\rm H^+\)]

[\(\rm H^+\)] = \(\rm 10^-^2^.^7\)

[\(\rm H^+\)] = 1.9 \(\rm \bold{\times\;10^-^3}\) M

Explanation:

I did the question before and got it right.

The mass of an object is 7.1788g.

We are provided with the following information:

The density of an object = 1.37 \(g/cm^{3}\)

Volume of an object = 5.24 \(cm^{3}\)

Density of any substance is defined as the ratio of mass of the substance to the volume of the substance. Density is represented by ρ. The SI unit of density is kg/m³.

Density of an object = (Mass of an object) / (Volume of an object)

On substituting the value of density of an object and volume of an object, we get

1.37 \(g/cm^{3}\) = ( Mass of an object )/ 5.24 \(cm^{3}\)

Mass of an object = (1.37 \(g/cm^{3}\) ) × ( 5.24 \(cm^{3}\) )

Mass of an object = 7.1788 g

Thus, we can conclude that the object has a mass of 7.1788 g.

Explanation:

To find the mass, you need to (1) convert molecules to moles (via Avogadro's Number) and then (2) convert moles to grams (via molar mass from periodic table values). It is important to arrange the ratios/ conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 4 sig figs to reflect the given value (2.408 x 10²⁴).

Avogadro's Number:

1 mole = 6.022 x 10²³ molecules
