how many miles of hydroxide are in 8.02 x 10^25 particles of hydroxide? (explain your answer)​

The forces between molecules are much stronger than the forces between ions.

➜ True

The actual relative strengths will vary depending on the molecules involved. Ionic bonding and covalent bonding will always be stronger than intermolecular forces in any given substance.

A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.

A person would weight more on Neptune than on planet earth because the gravitational force in neptune is more.

Gravitational forces is a kind of attraction force which is present between two objects of masses.

Gravitational force on the neptune planet is more as compared to the gravitational force on the earth. So the mass of any object present in the neptune is more than the earth.

Hence a person would weight more on Neptune than on planet earth because gravitatinal force in neptune is more.

Answer:

The percentage by mass of lithium in one mole of Li₃N is approximately 59.78%

Explanation:

The given compound is Li₃N

The atomic mass of lithium, Li = 6.94 amu

The atomic mass of nitrogen, N = 14.01 amu

Therefore by definition, we have;

The mass of one mole of lithium, Li = 6.94 g

The mass of one mole of nitrogen, N = 14.01 g

One molecule of Li₃N contains 3 atoms of lithium, Li and 1 atom of nitrogen, N

The mass of one mole of Li₃N = The molar mass of Li₃N = 3 × The mass of one mole of lithium + The mass of one mole of nitrogen

∴ The mass of one mole of Li₃N = 3 × 6.94 g + 14.01 g = 34.83 g

The percentage by mass of lithium, Li, in one mole of Li₃N = 3×6.94/(34.83) × 100 ≈ 59.78%

The percentage by mass of lithium in one mole of Li₃N ≈ 59.78%.

Answer: The spectrum would be continuous

Explanation:

Atomic transitions allow us to find that the correct answer to what would happen if there was no quantization is:

          d. the spectrum would be continous

In the models of atoms the correct explanation for the energy was given by Planck, by establishing that the energy of an electron is:  

           E = h ν

Where E is the energy, h the Planck constant and ν the frequency.

Therefore a transition occurs as the jump of an electron from one level to another  

          ΔE = E₂ - E₁

In all atomic models the levels are discrete, so the jumps are also discrete.

If the levels were continuous, the energy difference between the lines disappears and we have a continuous emission spectrum.

Let's review the different answers:

a. False. The lines disappear

b. False. This for if the separation between levels increases, which is the opposite process to the one analyzed.

c. False. The lines disappear

d) True. The spectrum is a continuum without any separation.

In conclusion, using the atomic transitions we find that the correct answer for what would happen if there was no quantization is:

     d. the spectrum would be constnuous

Answer:

Percient yield of reaction: 85 %

Explanation:

The reaction is:

PCl₃ + 3H₂O → H₃PO₃ + 3HCl

We only have data from the chloride, so we assume water is in excess. We convert the mass to moles:

62 g . 1mol / 137.32 g = 0.452 mol

If ratio is 1:3, from 0.452 mol we would produce three times as big, that amount. (0.452 . 3) = 1.36 moles of HCl.

We convert the amount to mass.

1.36 mol . 36.45g / 1mol = 49.4 g

This value of produced HCl is the theoretical yield. To determine the percent yield we make:

(Yield produced / Theoretical yield) . 100

(42 g / 49.4g) . 100 = 85%

Answer:

Yes it is 85.0%

Balanced equation : C. CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

CH₄ + Cl₂⇒  CCl₄+ HCl

aCH₄ + bCl₂⇒  CCl₄+ cHCl

C, left=a, right=1⇒a=1

H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4

Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4

The equation becomes :

CH₄ + 4Cl₂⇒  CCl₄+ 4HCl
