What information should be recorded in the last row of the table?

Answers

Answer: the density of the rock

55.91g/ml

Explanation:

The density of the rock after it had being placed in the cylinder of water so the calculation should look like this:

Volume of water substract the mass of the rock:

And that is 142.5 ml - 86.59g =

Answer 55.91 g/ml

calculate the number of neutrons in potassium-40.

Answers

Potassium electrons=19, protons =electrons. No of neutrons= no of mass - no of protons. 40-19=21.Ans =21 neutrons

Considering the definiton of atomic number and atomic mass, the number of neutrons of the potassium is 21.

All atoms are composed of a central nucleus in which there are particles with a positive electric charge, the protons, and a neutral charge, the neutrons, around which other particles with a negative electric charge, which are electrons, move.

Atoms of different elements have different amounts of protons. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom. This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element.

On the other side, the atomic mass (A) is defined as the sum of number of protons and number of neutrons:

Atomic mass = Number of protons  + Number of neutrons

In this case, the potassium (K) elements has atomic number 19. That means, the number of of protons is equal to 19. And the atomic mass is 40. So, the number of neutrons is calculated as:

40= 19  + Number of neutrons

Solving:

Number of neutrons= 40 - 19

Number of neutrons= 21

Hence, the number of neutrons of the potassium is 21.

A mixture of the gases neon and krypton is in a 2.00 L container with a pressure of 1.60 atm. The partial pressure of the neon is 0.40 atm. What is the partial pressure of the krypton?

Answers

Answer:

P(Kr) = 1.2 atm

Explanation:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

Now we will solve this  problem by using this law

Total pressure = 1.60 atm

Partial pressure of neon = 0.40 atm

Partial pressure of krypton = ?

Solution:

P(total) = P(Ne)+ P(Kr)

1.60 atm = 0.40 atm +P(Kr)

P(Kr) = 1.60 atm -  0.40 atm

P(Kr) = 1.2 atm

The partial pressure of Krypton in the mixture has been 1.2 atm.

Partial pressure can be defined as the pressure exerted by a single gas in the solution.

According to Dalton’s law of partial pressure, the total pressure of the gas has been the summation of the partial pressure of each gas present in the mixture.

Total pressure = Partial pressure of A + Partial pressure of B + Partial pressure of C……

The given mixture has been consisted of neon and krypton. The total pressure of the mixture has been:

Total pressure = Partial pressure of Ne + Partial pressure of Kr

The total pressure = 1.60 atm.

The partial pressure of Ne = 0.40 atm.

Substituting the values:

1.60 atm = 0.40 atm + Partial pressure of Kr

Partial pressure of Kr = 1.60 - 0.40 atm

Partial pressure of Kr = 1.2 atm.

The partial pressure of Krypton in the mixture has been 1.2 atm.

Why do clothes stick together when coming out of a dryer? And do the clothes start off as neutral?

Answers

here is what came up when i searched it up:

"The attraction between protons and electrons can also make clothes stick together in the dryer. When you dry clothes in the dryer, different fabrics rub together, and electrons from a cotton sock (for instance) may rub off onto a polyester shirt."

Sometimes, clothes can get stuck together after they come out of a dryer because of static electricity.

No, clothes may not start off as neutral. Whether clothes have static charges before going into the dryer depends on different things.

Why do clothes stick together when coming out of a dryer?  

Static electricity happens when certain things touch and create an uneven amount of electrons. This can cause one material to have a positive charge and the other to have a negative charge. When clothes move and touch each other in a dryer, this rubbing can cause static electricity.

If the clothes are cleaned and dried correctly, they should have no charge or be evenly charged.

There are various concepts to define acids and bases. Among which the first was Arrhenius theory. This theory states that, acids are substances which can furnish H+ in solution and bases are substances giving OH- in solution.

Then Bronsted- Lowry concept states acids as proton donor and bases as proton acceptors. The most applicable theory for acids and bases is Lewis concept.

An element X that has 15 protons and 15 electrons, loses three
electrons to form an ion.
What will be the charge on the ion?
What will be the number of protons and electrons in the ion?

Answers

Answer:

+3

12 electrons and 15 protons.

Explanation:

The element having 15 electrons and 15 protons have atomic number 15. We know that when an atom lose or gain the electron ions are formed.

Anion formation:

Anion is formed when electron is accept by an atom.

X + e⁻ → X⁻

Cation formation:

Cation is formed when electron lose be an atom.

X → X⁺ + e⁻

The given atom loses 3 electrons thus oxidation number will be +3 and cation is formed.

X → X³⁺ + 3e⁻

Now element X have 15 protons and 12 electrons.

Hydrofluoric acid (HF) can be prepared according to the following equation:
CaF2 + H2SO4 2 HF + CaSO4.
How many grams of HF can be prepared from 75.0 g of H2SO4 and 63.0 g of CaF2?
In the above problem, which reactant is limiting and which is in excess?

Answers

Given the balanced equation:

( Reaction type : double replacement)

CaF2 + H2SO4 → CaSO4 + 2HFI

We can determine the number of grams prepared from the quantity of 75.0 H2SO4, and 63.0g of CaF2 by converting these grams to moles per substance.

This can be done by evaluating the atomic mass of each element of the substance, and totaling it to find the molecular mass.

For H2SO4 or hydrogen sulfate it's molecular mass is the sum of the quantity of atomic mass per element. H×2 + S×1 + O×4 = ≈1.01×2 + ≈32.06×1 + ≈16×4 = 2.02 + 32.06 + 64 = 98.08 u (Dalton's or Da) or g / mol.

For CaF2 or calcium fluoride, it's molecular mass adds 1 atomic mass of calcium and 2 atomic masses of fluoride due to the number of atoms.

Ca×1 + F×2 = ≈40.07×1 + ≈19×2 = 40.08 + 38 = 78.07 u (Da or Dalton's) or g / mol.

The limiting  reactant in the given balanced reaction is sulphuric acid. The mass of HF produced from 75 g of H₂SO₄ is 30 g.

What is limiting reactant?

The limiting reactant in a species is the reactant which is fewer in amount and thus determine the yield of the product.

In the given reaction, one mole of calcium fluoride reacts with one mole of sulphuric acid to give two moles of HF. The molar mass of calcium fluoride CaF₂ is 78 g/mol the weight taken here is 63 g. Thus number of moles is 63/78 = 0.87 moles.

The molar mass of sulphuric acid H₂SO₄ is 100g/mol. The weight taken here is 75 g and thus, number of moles is 75/100 = 0.75 moles. One mole of calcium fluoride need one mole of H₂SO₄ . Thus 0.87 neede 0.87 moles of H₂SO₄ . But here we have only 0.75. Thus it is the limiting reactant.

As per the reaction, one mole or 100 g of H₂SO₄  produce 2 moles or 40 g of HF (molar mass = 20 g/mol). Thus mass of HF produced from 75 g is calculated as follows:

mass of HF = (75 × 40)/100

                   =  30 g.

Hence, mass of HF produced in this reaction is 30 g.

Answers

Explanation:

The kinetics of radioactive decay follows the equation:

Where N could be taken as mass after time t,

N₀ initial mass = 4.30g;

k is rate constant = ln 2 / t(1/2)

= ln 2 / 5730years = 1.2097x10⁻⁴ years ⁻¹

Replacing:

Ln (N / 4.30g) = -1.2097x10⁻⁴ years ⁻¹ * 50000 years

N / 4.30 = 2.36x10⁻³
