The total charge that flows while the battery is being charged is approximately 193,939.39 Coulombs.

To calculate the total charge that flows while the battery is being charged, we can use the relationship between electrical energy, potential difference, and charge.

The electrical energy (E) stored in the battery is given as 64 mega Jules (64 MJ). The potential difference (V) provided by the battery is 330 volts. We know that the energy (E) is equal to the product of the potential difference (V) and the charge (Q):

E = V * Q

Since the charging process is 100% efficient, all the electrical energy supplied is stored in the battery. Therefore, we can rearrange the equation to solve for the charge (Q):

Q = E / V

Substituting the given values, we have:

Q = 64 MJ / 330 V

To perform the calculation, we need to convert mega Jules (MJ) to joules (J) since the SI unit of energy is joules. One mega Joule is equal to 1 million joules:

Q = (64 * 10^6 J) / 330 V

Calculating the division:

Q ≈ 193,939.39 Coulombs

Therefore, the total charge that flows while the battery is being charged is approximately 193,939.39 Coulombs.

This value represents the quantity of electric charge transferred during the charging process, and it indicates the amount of electricity that enters the battery.

The mass of aluminum that will combine with 16.5 g of oxygen is 75.64 g.  

The mass of aluminum that will combine with 16.5 g of oxygen, we need to first convert the mass of oxygen from grams to moles, since the reaction will occur at a fixed temperature and pressure.

1 mole of oxygen contains \(6.022 * 10^{23\) atoms, so 16.5 g of oxygen contains:

16.5 g /  \(6.022 * 10^{23\) atoms/mole = 0.00027 moles of oxygen

Next, we need to convert the number of moles of oxygen to moles of aluminum. The equation for the reaction is:

\(Al_2O_3 + 3O_2 - > 2Al_2O_3\)

Since we are combining 1 mole of oxygen with 3 moles of aluminum oxide, we can write the equation as:

\(16.5 g (O_2) + 3 x 0.00027 mol Al_2O_3 == 2 * 0.00027 (mol) Al_2O_3\)

We can now solve for the mass of aluminum by dividing both sides of the equation by 2 and multiplying by the molar mass of aluminum oxide (44.01 g/mol):

mass of aluminum = (16.5 g O2 x 44.01 g/mol) / (2 x 0.00027 mol)

mass of aluminum = 75.64 g

Therefore, the mass of aluminum that will combine with 16.5 g of oxygen is 75.64 g.

Answer:

The electronic configuration of ions formed are:

Li+ (2) => 1s2

Cl- (18) => 1s2 2s2 2p6 3s2 3p6

Explanation:

Lithium metal, Li will lose 1 electron to lithium ion Li+. Chlorine atom, Cl will receive the 1 electron to form the chloride ion Cl- as shown by the following equation below:

Li —> Li+ + e

Cl+ e —> Cl-

Combine both equation

Li + Cl + e —> Li+ + Cl- + e

Cancel out 'e'

Li + Cl —> Li+ Cl-

Thus, we can write the electronic configuration for the reaction as follow:

Before reaction:

Li (3) => 1s2 2s1

Cl (17) => 1s2 2s2 2p6 3s2 3p5

After reaction

Li+ (2) => 1s2

Cl- (18) => 1s2 2s2 2p6 3s2 3p6

Therefore, the electronic configuration of the ions formed are:

Li+ (2) => 1s2

Cl- (18) => 1s2 2s2 2p6 3s2 3p6

The NO3 is zero atm (atmospheric pressure at sea level).

What is partial pressure?

The pressure that one gas in a gas mixture will exert if it fills the same volume by itself is referred to as partial pressure.

What is spontaneous?

A spontaneous process is one that takes place without the use of external energy. For instance, a ball will roll down an incline, water will flow downward, ice will melt into water, radioactive elements will decay, and iron will rust.

N2O(g)+NO2(g)⇌3NO(g)

dG = G products-  G reactants

dG = 3*86.56696 - (104.1816 + 51.29584) = 104.22344 kJ/mol

since dG > 0, this must not favor produces, i.e. it is nonspontaneous

dG = -RT*ln(Kp)

Kp = exp(-dG/(RT))

Kp = exp(-104223.44/(8.314*298)) = 5.37818739*10^-19

Kp = NO^3 / (N2O)(NO2)

initially

NO= 0

N2O = 1

NO2 = 1

in equilibrium

NO= 0 + 3x

N2O = 1  -  x

NO2 = 1 - x

substitute

5.378 *10^-19 = (3x)^3 / (1-x)(1-x)

(5.378 *10^-19)(1 -2x +x^2)  = 27x^3

x = partially 0 atm

therefore

Almost no NO3 will be zero

Not possible, since

dG = dG º + RT*ln(Q)

therefore, even though we can decrease T, it will never be negative, meaning than this will be never spontaneous

Therefore, Almost no NO3 will be zero.

Oxidation is defined as:

Reduction is defined as:

Looking at the first reaction, the Mg atom gains oxygen to become MgO. This means that Mg is oxidized. The oxidizing agent is O2. At the same time, O2 is being reduced and the reducing agent is Mg.

For the second reaction, the oxidation number of Pb is reduced from +2 to 0. Thus, Pb has been reduced by Zn while Zn itself has been oxidized. The reducing agent here is Zn while the oxidizing agent is Pb(NO3)2.

\(m_{Cu}=0.99gCu\)

Explanation:

Hello!

In this case, considering the given chemical reaction and the mass of the magnesium strip, following the indications of the atomic weight ratio (2.61 g Cu/1 g Mg), and keeping in mind the 1:1 mole ratio one could compute the produced mass of copper as shown below:

\(m_{Cu}=0.38gMg*\frac{2.61gCu}{1gMg} \\\\m_{Cu}=0.99gCu\)

Best regards!

In part 1, the magnesium strip weighed 0.38g. If each copper atom is 2.61 times heavier than a magnesium atom, we can set up the equation:

\(\frac{0.38mg}{1} x \frac{2.61cu}{1mg} =\frac{0.38x2.61}{1} = 0.99cu\)

The mass of the copper that can be produced is 0.99g.

The limiting component or reactant in a chemical process is the one that controls how much product is created. Because metals and compounds respond in a balanced chemical equation according to their mole ratios, a limiting reactant is necessary.

When a chemical reaction is complete, the limiting reagent—also known as the limiting reactant or limiting agent—is the component that has been completely consumed.  Since the process cannot proceed without this reagent, the quantity of product that can be produced is constrained.

Excess reagents or surplus reactants are any chemicals that are present in amounts greater than those necessary to cause a reaction with the limiting reagent (sometimes abbreviated as "xs").

Solutions can be classified as acidic, neutral, or basic based on the relative amounts of hydrogen ions (H+) and hydroxide ions (OH-) present. An acidic solution has a higher concentration of hydrogen ions than hydroxide ions, while a basic solution has a higher concentration of hydroxide ions than hydrogen ions. A neutral solution has an equal concentration of both ions.

Solutions are classified as acidic, neutral, or basic based on the concentration of hydrogen ions (H+) and hydroxide ions (OH-) present in the solution. In an acidic solution, there is a higher concentration of hydrogen ions than hydroxide ions, resulting in a lower pH value (pH < 7). In contrast, a basic solution has a higher concentration of hydroxide ions than hydrogen ions, leading to a higher pH value (pH > 7). A neutral solution has an equal concentration of hydrogen ions and hydroxide ions, resulting in a pH value of 7. The pH scale is a measure of the acidity or basicity of a solution, with lower values indicating acidity, higher values indicating basicity, and 7 representing neutrality.

Answer:

Percentage of O = 56.1 %

Percentage of Al =15.8%

Percentage of S = 28.1 %

Explanation:

Given compound Al₂(SO₄)₃

Molar mass of compound:

27×2 + 32×3 + 16×12 = 342 g/mol

Percentage of Al = ( Mass of Al / Total mass ) × 100

Percentage of Al = 54 /342 × 100

Percentage of Al =15.8%

Percentage of S = ( Mass of S / Total mass ) × 100

Percentage of S = 96 /342 × 100

Percentage of S = 28.1 %

Percentage of O = ( Mass of O / Total mass ) × 100

Percentage of O = 192 /342 × 100

Percentage of O = 56.1 %

The concentration of copper (II) sulfate when it's absorbance is 2.17 is 0.22 M.

The concentration of copper (II) sulfate when it has absorbance value 2.17 is found out by  cross multiplying  concentration of 0.10 M solution with it's absorbance and then dividing it by absorbance of 0.10 M copper sulfate solution.That is,

0.10×2.17/0.96=0.22 M

The law suggests a linear relationship between absorbance and concentration of a solution.The law states that, absorbance of a solution is directly proportional to the concentration and the path length that is,

A=C×l

where l=path length

Thus, it can be inferred from the law that as absorbance of solution increases it's concentration also increases as they are directly proportional.
