at constant pressure, what happens to the volume of a gas at 298 k, when the temperature doubles to 596 k?

Answer:

A!!!!!!!!

Explanation:

We can separate the mixture of copper and salt by putting both mixtures in water. Salt will dissolve and copper will not. We can separate them easily.

Salt can dissolve in water because it is a soluble substance. Salt is made up of the negative ion of an acid and the positive ion of the base. When an acid and base dissolve neutralization reaction occurs.

Copper doesn't dissolve in water because copper is a metal. Not even in salty water. Copper has great metal conductivity. The melting and boiling point of copper is very high, that is, 1084.32 degrees Celsius and 2562 degrees Celsius.

Copper metal doesn't dissolve in water however exposure to such metals to air adds a layer of oxide to the metal. The oxide layer does dissolve in water to a slight extent.

The four mole ratios are: 6 KOH / 2 K₃PO₄, 2 KOH / 1 Co₃(PO₄)₂,

1 K₃PO₄ / 1 Co₃(PO₄)₂, 1 Co(OH)₂ / 2 KOH.

Mole ratio refers to the ratio between the number of moles of two substances in a chemical reaction.

The given chemical equation is:

2 KOH + Co₃(PO₄)₂ → K₃PO₄ + Co(OH)₂

And the first mole ratio given is:

6 KOH / 2 K₃PO₄

To find the other mole ratios, we need to first balance the chemical equation. It is already balanced, so we can proceed to find the other mole ratios:

(2) 2 KOH / 1 Co₃(PO₄)₂

This ratio indicates that two moles of potassium hydroxide react with one mole of cobalt(II) phosphate.

(3) 1 K₃PO₄ / 1 Co₃(PO₄)₂

This ratio indicates that one mole of potassium phosphate is produced for every mole of cobalt(II) phosphate that reacts.

(4) 1 Co(OH)₂ / 2 KOH

This ratio indicates that one mole of cobalt(II) hydroxide is produced for every two moles of potassium hydroxide that react.

Therefore, the four mole ratios are:

(1) 6 KOH / 2 K₃PO₄

(2) 2 KOH / 1 Co₃(PO₄)₂

(3) 1 K₃PO4 / 1 Co₃(PO₄)₂

(4) 1 Co(OH)₂ / 2 KOH

A single electron is present in the valence shell of sodium shown.

What is a valence shell?

In chemistry and physics, the valence electron is an electron that is part of the outer shell of an atom. When the outer shell is open, the valence electron can participate in the formation of a chemical bond. Each atom in a bond contributes a valence electron and forms a common pair in a single covalent bond. The valence shell of an atom refers to its outermost orbit or shell. These electrons are necessary for creating bonds between atoms. It can be filled whole or in part.

So, as you can see from the diagram, we see that there is only one electron in the valence shell.

Explanation:

The balanced chemical equation for the formation of [HgI4]2- complex from Hg2+ and I- ions is:

Hg2+(aq) + 4I-(aq) ⇌ [HgI4]2-(aq)

The equilibrium constant expression is:

Kf = [HgI4]2- / [Hg2+][I-]4

We are given Kf = 6.76 x 10^29 and the initial concentrations of Hg2+ and I- ions. Let x be the equilibrium molarity of Hg2+ ion, then the molarity of I- ion will be 4x (because 4 moles of I- ions react with 1 mole of Hg2+ ion to form the complex).

The concentration of Hg2+ ion at equilibrium is:

[Hg2+] = 0.0054 M - x

The concentration of I- ion at equilibrium is:

[I-] = 0.10 M - 4x

Substituting the values in the equilibrium constant expression, we get:

6.76 x 10^29 = ([HgI4]2-) / ([Hg2+] [I-]4)

6.76 x 10^29 = ([HgI4]2-) / ((0.0054 - x) (0.10 - 4x)4)

Assuming that x is much smaller than 0.0054 and 0.10, we can simplify the expression to:

6.76 x 10^29 ≈ ([HgI4]2-) / (0.00016 x4)

[HgI4]2- ≈ 6.76 x 10^29 x 0.00016 x4

[HgI4]2- ≈ 0.277 M

Therefore, the equilibrium molarity of Hg2+ ion is:

[Hg2+] = 0.0054 M - x ≈ 0.0054 M - 0.058 M = -0.052 M

Since the resulting concentration of Hg2+ ion is negative, it means that the assumption that x is much smaller than 0.0054 and 0.10 is not valid, and we need to use a quadratic equation to solve for x. The resulting value of x will be positive and represents the equilibrium molarity of Hg2+ ion.

Solving the quadratic equation, we get:

[Hg2+] = 5.1 x 10^-11 M

Therefore, the equilibrium molarity of aqueous Hg2+ ion is 5.1 x 10^-11 M.

If the frog cells swell and burst while the human cells shrink means that the solution will be hypotonic for frog cells while for human cells the solution will be hypertonic.

These changes will occur because in the frog cell there will be higher concentrations of ions than in the extracellular space, so water will enter the cell by osmosis to equalize the concentrations of the cells. While in the human cell there will be a lower concentration of ions than outside the cell, for this reason the water leaves it in order to equalize the concentrations both inside and outside the cell. Being then the hypotonic solution for the frog cell and hypertonic for the human cell.

Therefore, we can confirm that if the frog cells swell and burst while the human cells shrink means that the solution will be hypotonic for frog cells while for human cells the solution will be hypertonic.

The mole ratio for Potassium and Sodium in the balanced equation 2 Na + K2S → 2K + Na2S is 2:2 or 1:1.

To find the mole ratio, we need to look at the coefficients in front of the elements in the balanced equation. The coefficient for Sodium (Na) is 2 and the coefficient for Potassium (K) is also 2. This means that for every 2 moles of Sodium, there are 2 moles of Potassium. We can simplify this ratio by dividing both sides by 2 to get a 1:1 ratio.

So, the mole ratio for Potassium and Sodium in this balanced equation is 1:1. This means that there is an equal amount of moles of Potassium and Sodium in the reaction.

Explanation:

To find the volume, you take the mass and divide it by the density

Answer:

This question is incomplete. The completed question is below

Procedure

1. Read and complete a lab safety form.

2. Place about 50 copper pellets into  a plastic petri dish. Place the cover  on the dish, and secure it with tape.

3. Hold the dish by the edges. Gently  vibrate the dish from side to side no  more than 1–2 mm. Observe the  pellets. Record your observations in  your Science Journal.

4. Repeat step 3, vibrating the dish less  than 1 cm from side to side.

5. Repeat step 3, vibrating the dish  3–4 cm from side to side.

if the pellets represent particles in matter, what do you think the shaking represents?

Explanation:

This procedure seeks to illustrate the "properties" of particles in matter. The shaking of the pellets represents the movement of the particles of matter (which occurs in liquids and gases). This is because the movement of particles in a liquid and gaseous state freely moves around (reason the petri-dish was vibrated so the pellet particles which serve as the liquid/gaseous particles can move freely).

NOTE: The particles in a solid have a highly restricted movement (or no movement) because of the compact nature of the particles within the solid.

The new pressure in kPa is 183.83 kPa.

To find the new pressure in kPa, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at constant temperature.

According to Boyle's Law:

P₁ * V₁ = P₂ * V₂

Where:

P₁ = initial pressure (in mmHg)

V₁ = initial volume (in L)

P₂ = new pressure (in mmHg)

V₂ = new volume (in L)

Given:

P₁ = 915.6 mmHg

V₁ = 12.16 L

V₂ = 6.55 L

Rearranging the equation to solve for P₂:

P₂ = (P₁ * V₁) / V₂

Substituting the given values into the equation:

P₂ = (915.6 mmHg * 12.16 L) / 6.55 L

Converting mmHg to kPa (1 mmHg = 0.133322 kPa):

P₂ = (915.6 * 0.133322 kPa * 12.16 L) / 6.55 L

Simplifying the equation:

P₂ ≈ 183.83 kPa (rounded to two decimal places)

The new pressure in kPa, when the gas is transferred to a smaller container, is approximately 183.83 kPa. This calculation is based on Boyle's Law, which describes the inverse relationship between pressure and volume for a gas at constant temperature.

The IUPAC name  of the oxyacid formed from chlorite is chlorous acid.

All oxyacids have the acidic hydrogen bound to an oxygen atom, so bond strength (length) is not a factor, as it is with binary nonmetal hydrides. Rather, the electronegativity of the central atom and the number of oxygen atoms determine oxyacid acidity. For oxyacids with the same central atom, acid strength increases with the number of oxygen atoms attached to it. With the same number of oxygen atoms attached to it, acid strength increases with increasing electronegativity of the central atom.

Compared to the salts of their deprotonated forms (a class of compounds known as the oxyanions), oxyacids are generally less stable, and many of them only exist formally as hypothetical species, or only exist in solution and cannot be isolated in pure form.

Thus, the IUPAC name  of the oxyacid formed from chlorite is chlorous acid.

In thermochemistry, an exothermic process is one "for which the overall standard enthalpy change H is negative." Exothermic processes typically result in heat. A reaction for which the overall standard Gibbs energy change G is negative is what the term "reaction" according to the IUPAC means.

The exergonic response and the phrase are commonly mistaken. A very exothermic reaction will often accompany an exergonic reaction since "H" significantly contributes to "G." The majority of the remarkable chemical reactions presented in classrooms are exothermic and exergonic processes.
