Carla applied a force of 35 N to a wheelbarrow full of bricks and moved it 2.5 m. Which of the following can be determined from this information?

Answer:

Nickel Nitrate

The equilibrium constant for the system at this temperature is\(1.17 × 10^-31 mol^2/L^2\).

For the chemical equation:

N2(g) + O2(g) ⇌ 2NO(g)

The equilibrium mixture at a temperature of 1500 K is determined to contain 6.4 × 10^-3 mol/L of N2,\(1.7 × 10^-3\)mol/L of O2 and 1.1 × 10^-5 mol/L of NO.  First, we need to calculate the concentration of N2 and O2 required to produce

1.1 × 10^-5 mol/L of NO:

2NO(g) = N2(g) + O2(g)

Given that there are 1.1 × 10^-5 mol/L of NO, the number of moles of N2 and O2 are equal since the stoichiometric ratio is 1:1. Therefore:

\(1.1 × 10^-5 mol/L\) = [N2][O2]Kc = \(([NO]^2)/([N2][O2])Kc\)= \((1.1 × 10^-5 mol/L)^2/(6.4 × 10^-3 mol/L)(1.7 × 10^-3 mol/L)Kc\) =

1.17 × 10^-31 mol^2/L^2.

Answer:

1.01×10⁻¹⁶ moles (to 3 significant figures)

Explanation:

Using avocado's constant, we can use it to find the number of moles (x) for 61,000,000 atoms of Ne:

1 mole = 6.02×10²³ atoms

x = 61,000,000 atoms

We can solve this by cross-multiplying:

6.02×10²³ × x = 1 × 61,000,000

6.02×10²³x = 61,000,000

To solve for x, divide both sides by 6.02×10²³x:

\( \frac{6.02×10²³x}{6.02×10²³} = \frac{61,000,000}{6.02×10²³ } \)

This cancels out both 6.02×10²³ on the left

\(x = \frac{61,000,000}{6.02×10²³ } \)

\(x = 1.01 \times 10⁻¹⁶\)

Explanation:

Answer:

pH and pOH are related to one another; THEY ARE NOT INDEPENDENT OF EACH OTHER. As pH increases, pOH decreases. As pH decreases, pOH increases. By knowing what ion you are measuring on which scale, this will tell you whether or not the solution is acidic or basic.

Explanation:

So now i don't know if that will get more or less basic. But errr.... Hope this helps!!

If the pOH increases is a solution, the solution is getting less basic and more acidic.

We know that when pH increases, pOH decreases. We also know that when pH increases acidity decreases and basic nature of solution increases but in pOH, the sequence is opposite. When pOH increases acidity increases and basic nature of solution decreases.

So we can conclude that If the pOH increases is a solution, the solution is getting less basic and more acidic.

These substances have dispersed particles that are large enough to scatter light, making the beam visible. Therefore, out of the options provided, a mixture that scatters light is an example of a colloid. Option B)

A colloid is a type of mixture in which particles are dispersed throughout a medium, creating a homogeneous appearance. Unlike solutions, where the particles are completely dissolved, and suspensions, where the particles settle out, colloids have particles that are larger than those in solutions but smaller than those in suspensions. One characteristic of colloids is that they can scatter light due to the size of the particles. This scattering of light is known as the Tyndall effect. Examples of colloids include milk, fog, and aerosol sprays. These substances have dispersed particles that are large enough to scatter light, making the beam visible.

The pH of 0.335 M trimethylammonium chloride, (CH3)3NHCI is approximately 5.676.

What is pH?

To find the pH of the solution, we need to first determine if (CH3)3NHCI acts as an acid or base. Since (CH3)3NHCI is a salt composed of a weak base, trimethylamine, and a strong acid, hydrochloric acid (HCI), it will undergo hydrolysis in water.

The hydrolysis reaction is given by:

(CH3)3NH+ (aq) + H2O (l) ⇌ (CH3)3N (aq) + H3O+ (aq)

The Kb expression for the equilibrium reaction is:

Kb = [ (CH3)3N ] [ H3O+ ] / [ (CH3)3NH+ ]

Since (CH3)3NH+ and HCl dissociate completely in water, the initial concentration of (CH3)3NH+ is equal to the concentration of (CH3)3NHCI, which is 0.335 M.

Using the Kb value given, we can solve for the concentration of H3O+:

Kb = 6.3 x \(10^{-5}\) = [ (CH3)3N ] [ H3O+ ] / 0.335

[ H3O+ ] = Kb x (CH3)3NH+ / (CH3)3N

[ H3O+ ] = 6.3 x \(10^{-5}\) x 0.335 / 1

[ H3O+ ] = 2.1095 x \(10^{-6}\) M

Finally, we can calculate the pH using the expression:

pH = -log [H3O+]

pH = -log (2.1095 x \(10^{-6}\))

pH = 5.676

Therefore, the pH of the solution is approximately 5.676.

A solution is a homogeneous mixture of a solute and a solvent. Both can be solid, liquid, or gas. Solutions exist for every possible phase of the solute and the solvent.

A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. Remember, solutions are homogeneous mixtures.

You can find many solutions in your daily life.

For example, solutions are salt and water, rubbing alcohol, and sugar dissolved in water.

Let's take salt and water.

Solute here is the salt and the water is the solvent. The amount of solvent is higher than solute in a solution.

When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. That is why the mixture of salt and water is a solution.

The reaction equation can be shown as;

Answer:

(see below)

Explanation:

First, refer to the pH scale:

1  2  3  4  5  6        7        8  9  10  11  12  13  14

<==  acidic        neutral             basic  ==>

You can see that the smaller the number, the stronger the acid and the bigger the number, the more basic the base is. 7 is neutral, such as water. it's neither basic nor acidic.

Now, using the process of elimination:

A) It's a strong basic solution.

No, because this solution's pH hasn't even reached basic.

B) It's a weak acidic solution.

Yes, because it is acidic and it's just a little bit more acidic than a neutral solution.

C) It's a weak basic solution.

No, because this solution's pH hasn't even reached basic.

D) It's a strong acidic solution.

No, because even though it's acidic, it's just below neutral. For something to be a strong acidic solution would be around a pH of 3.

So the answer would be B) It's a weak acidic solution.

Explanation:

In the J = 0 state, the BrF molecule does not undergo any revolutions per second. In the J = 1 state, it undergoes approximately 0.498 revolutions per second, and in the J = 10 state, it undergoes approximately 15.71 revolutions per second.

To calculate the rotational constant B, we can use the formula:

B = 1 / (2 * π * Δν)

Where:

B = rotational constant

Δν = spacing between consecutive lines in the rotational spectrum

Given that the spacing between consecutive lines is 0.71433 cm^(-1), we can substitute this value into the formula:

B = 1 / (2 * π * 0.71433 cm^(-1))

B ≈ 0.079 cm^(-1)

The moment of inertia (I) of the molecule can be calculated using the formula:

I = h / (8 * π^2 * B)

Where:

h = Planck's constant

Given that the value of Planck's constant (h) is approximately 6.626 x 10^(-34) J·s, we can substitute the values into the formula:

I = (6.626 x 10^(-34) J·s) / (8 * π^2 * 0.079 cm^(-1))

I ≈ 2.11 x 10^(-46) kg·m^2

The bond length (r) of the molecule can be determined using the formula:

r = sqrt((h / (4 * π^2 * μ * B)) - r_e^2)

Where:

μ = reduced mass of the molecule

r_e = equilibrium bond length

To calculate the wavenumber (ν) of the J = 9+ to J = 10 transition, we can use the formula:

ν = 2 * B * (J + 1)

Substituting J = 9 into the formula, we get:

ν = 2 * 0.079 cm^(-1) * (9 + 1)

ν ≈ 1.58 cm^(-1)

To determine the most intense spectral line at room temperature (300 K), we can use the Boltzmann distribution law. The intensity (I) of a spectral line is proportional to the population of the corresponding rotational level:

I ∝ exp(-E / (k * T))

Where:

E = energy difference between the levels

k = Boltzmann constant

T = temperature in Kelvin

At room temperature (300 K), the population distribution decreases rapidly with increasing energy difference. Therefore, the transition with the lowest energy difference will have the most intense spectral line. In this case, the transition from J = 0 to J = 1 will have the most intense spectral line.

To calculate the number of revolutions per second, we can use the formula:

ω = 2 * π * B * J

Where:

ω = angular frequency (in radians per second)

J = rotational quantum number

For J = 0:

ω = 2 * π * 0.079 cm^(-1) * 0 = 0 rad/s

For J = 1:

ω = 2 * π * 0.079 cm^(-1) * 1 ≈ 0.498 rad/s

For J = 10:

ω = 2 * π * 0.079 cm^(-1) * 10 ≈ 15.71 rad/s

Answer:

A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells

Explanation:

Beryllium (Be) is an element in group two of the periodic table with atomic number 4 (Is2 2s2). On the other hand, barium (Ba) is an element in group 2 of the periodic table with atomic number 56. However, as stated in the question, the Beryllium (Be) atom is smaller than the Barium (Ba) atom.

This is because a Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells. The electron shells of Barium contains more electrons, which is responsible for the large size of the Barium atom. Note that, the higher the number of atoms, the larger the atomic size.
