The percent composition of CuBr₂ is approximately 28.46% of Cu and 71.54% of Br.

To determine the percent composition of CuBr₂ (copper(II) bromide), we need to calculate the mass of each element in the compound and then divide it by the molar mass of the entire compound.

The molar mass of CuBr₂ can be calculated by adding up the atomic masses of copper (Cu) and bromine (Br) in the compound. The atomic masses of Cu and Br are approximately 63.55 g/mol and 79.90 g/mol, respectively.

Molar mass of CuBr₂ = (63.55 g/mol) + 2(79.90 g/mol) = 223.35 g/mol

Now, let's calculate the percent composition of each element in CuBr₂:

Percent composition of copper (Cu):

Mass of Cu = (63.55 g/mol) / 223.35 g/mol × 100% ≈ 28.46%

Percent composition of bromine (Br):

Mass of Br = 2(79.90 g/mol) / 223.35 g/mol × 100% ≈ 71.54%

Therefore, the percent composition of CuBr₂ is approximately:

- Copper (Cu): 28.46%

- Bromine (Br): 71.54%

These values represent the relative mass percentages of copper and bromine in the compound CuBr₂.

6.02 x \(10^{20\) formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

To convert formula units of MgCl₂ to moles of MgCl₂, we need to use Avogadro's number, which relates the number of formula units to the number of moles.

Avogadro's number (NA) is approximately 6.022 x 10^23 formula units per mole.

Given that we have 6.02 x 10^20 formula units of MgCl₂, we can set up a conversion factor to convert to moles:

(6.02 x 10^20 formula units MgCl₂) * (1 mol MgCl₂ / (6.022 x 10^23 formula units MgCl₂))

The formula units of MgCl₂ cancel out, and we are left with moles of MgCl₂:

(6.02 x 10^20) * (1 mol / 6.022 x 10^23) = 0.1 mol

Therefore, 6.02 x 10^20 formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

It's important to note that this conversion assumes that each formula unit of MgCl₂ represents one mole of MgCl₂. This is based on the stoichiometry of the compound, where there is one mole of MgCl₂ for every one formula unit.

Additionally, this conversion is valid for any substance, not just MgCl₂, as long as you know the value of Avogadro's number and the number of formula units or particles you have.

Answer:

0.0559 mol

Explanation:

Step 1: Given and required data

Step 2: Convert "P" to atm

We will use the conversion factor 1 atm = 760 torr.

750 torr × 1 atm/760 torr = 0.987 atm

Step 3: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 17.0 °C + 273.15 = 290.2 K

Step 4: Calculate the number of moles of air

If we assume air behaves as an ideal gas, we can calculate the moles (n) of air using the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 0.987 atm × 1.35 L/(0.0821 atm.L/mol.K) × 290.2 K = 0.0559 mol

The standard Gibbs free energy change of the reaction at 25°C is -18,262 J/mol.

Energy is the ability to do work. It exists in many forms, such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy (energy stored in the bonds of molecules), electrical energy (energy carried by electrons), and nuclear energy (energy produced in the nucleus of an atom).

The reaction given is a reversible reaction and the given Kp value is at 25°C. Therefore, we can use the equation ΔG°rxn = -RT ln Kp to calculate the standard Gibbs free energy change of the reaction.
We know that R = 8.314 J/mol K and T = 298 K (25°C)
Therefore, ΔG°rxn = - 8.314 J/mol K x 298 K x ln (2.26 x 10⁴)
ΔG°rxn = -18,262 J/mol
Therefore, the standard Gibbs free energy change of the reaction at 25°C is -18,262 J/mol.

the pressure required for 1.35 g of oxygen to dissolve in 1.5 L of water is 3.56 atm.

The first step in solving this problem is to identify the relevant equation.

Henry's law is the formula that relates the pressure of a gas above a liquid to the concentration of the gas that dissolves in the liquid.

In mathematical terms, Henry's law can be expressed as follows:P = kH * Cwhere P is the pressure of the gas, kH is Henry's law constant, and C is the concentration of the gas in the liquid.

To solve the problem, we need to first determine the value of kH using the given data.

kH can be calculated using the following formula:kH = P / CSubstituting the values given in the problem into this formula, we get:kH = 1.65 atm / (0.654 g / 1.5 L) = 3.97 atm/(g/L).

Now that we have the value of kH, we can use Henry's law to calculate the pressure required for 1.35 g of oxygen to dissolve in 1.5 L of water.

To do this, we simply rearrange the formula to solve for P:P = kH * CSubstituting the values of kH and C into this formula, we get:P = 3.97 atm/(g/L) * (1.35 g / 1.5 L) = 3.56 atm

Therefore, the pressure required for 1.35 g of oxygen to dissolve in 1.5 L of water is 3.56 atm.

There are 3.01 × 10^23 atoms of oxygen in 1.51×10^23 molecules of trifluoroacetic acid, C2HF3O2.

The formula of trifluoroacetic acid is C2HF3O2

Number of moles of the trifluoroacetic acid(C2HF3O2)is given using the approach;

1 mole of the compound contains 6.02 × 10^23 molecules

x moles of the compound contains 1.51 × 10^23 molecules

x = 1.51 × 10^23 molecules × 1 mole /6.02 × 10^23 molecules

x = 0.25 moles of  trifluoroacetic acid.

Now;

Number of O atoms in the sample = 0.25 × 2 × NA

Explanation:

So, this is the formula we can use to find the amount of each element:

Element count * Atomic mass = Mass

Plug in our elements for this:

Ca - 3*40.078=120.234

P - 2*30.973=61.946

Now, to find the percentage of mass, we must find total mass, and divide the two elements mass count by this total mass:

120.234+61.946=182.18

Now divide each element mass by the total mass:

Ca - 120.234/182.18=0.6599(Round to 0.65)

P - 61.946/182.18=0.34002(Round to 0.34)

Then multiply both numbers by 100 to get the percentage:

Ca - 65%

P - 34%

A gamma radiation is also known as gamma ray. It is a penetrating form of electromagnetic radiation arising from radioactive decay of atomic nuclei. It consists of shortest wavelength electromagnetic waves, even shorter than X-rays.

Gamma rays can pass through the human body completely and as they pass through, they cause ionizations that damage tissue and DNA.

As we know that E= hf

Hence, f= E/h

Given E=  6.96 x 10-14 J

And, Planck's constant, h = 6.626 *10^-34 m² kg/s

Possible Research Question: How does the number of wire wraps affect the strength of an electromagnet?

Trends noticed in the data: As the number of wire wraps (coils) around the nail increases, the magnetic strength of the electromagnet also increases. There is a positive correlation between the number of wire wraps and the number of paper clips the magnet picks up.

Claim based on the data: The magnetic strength of an electromagnet increases as the number of wire wraps (coils) around the nail increases.

Evidence from the chart or graph supporting the claim: The graph shows that as the number of wire wraps increases from 4 to 12, the number of paper clips the magnet picks up also increases from 6 to 25. This suggests a positive correlation between the two variables.

Answer: A balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (\(NaN_{3}\)) into solid sodium and gaseous dinitrogen is \(2NaN_{3}(s) \rightarrow 2Na(s) + 3N_{2}(g)\).

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, \(NaN_{3}(s) \rightarrow Na(s) + N_{2}(g)\)

Here, number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

To balance this equation, multiply \(NaN_{3}\) by 2 on reactant side. Also, multiply Na by 2 and \(N_{2}\) by 3 on product side.

The equation will be rewritten as follows.

\(2NaN_{3}(s) \rightarrow 2Na(s) + 3N_{2}(g)\)

This equation contains same number of atoms on both reactant and product side. Hence, this equation is now balanced.

The symbols (s) and (g) depicts the physical state of substances present in the equation as solid and gas.

Thus, we can conclude that balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (\(NaN_{3}\)) into solid sodium and gaseous dinitrogen is \(2NaN_{3}(s) \rightarrow 2Na(s) + 3N_{2}(g)\).
