which of the following generates the most ions per mole of solute when dissolved in dilute aqueous solution? group of answer choices a. nahso4 b. mgcl2 c. nacl d. c2h5oh e. caso4

Answers

Answer 1

MgCl₂ generates the most ions per mole of solute when dissolved in dilute aqueous solution because MgCl₂ dissolves completely in aqueous solution and Molarity of MgCl₂ is higher than all given ionic compounds nahso4, nacl, c2h5oh and caso4.

The equation for the dissociation of MgCl₂ in an aqueous solution is:

MgCl₂→Mg²⁺ + 2Cl⁻

Based on the equation for the reaction, for every mole of magnesium ions present in the solution, there are two moles of chloride ions. This is the case because in order to balance the charges to form the compound, the total anionic and cationic charges should be equal.

What is Molarity ?

Molarity is a concentration in terms of moles per litre of solution. Because an ionic compound dissociates into its components cations and anions in solution, the key to the problem is identifying how many moles of ions are produced during dissolution.

What happens to the chemistry of the seawater as more co2 is absorbed into the oceans?.

Answers

As more co2 is absorbed into the oceans the pH decreases and the ocean becomes more acidic.

There is more CO2 evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide levels. The average pH of the ocean is currently 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean turns more acidic.

What is pH?

pH is a measurement of how acidic or basic an aqueous solution is in relation to other liquids. The phrase, which is frequently used in chemistry, biology, and agronomy, converts hydrogen ion concentrations, which typically vary between 1 and 1014 gram-equivalents per litre, into numbers between 0 and 14.

lithium has two naturally occurring isotopes, 6li and 7 li, with masses of6.015 amu and 7.016 amu, respectively. what is the relative abundance of each isotope?

Answers

The relative abundance of Li-6 =0.0749 = 7.49%

The relative abundance of Li-7 =1 - 0.0749 = 0.9251 =92.51%

Formula used to calculate average atomic mass follows:

Avg atomic mass = ∑(atomic mass of an isotope) x (fractional abundance) ....(1)

Let the fractional abundance of Li-6 isotope be 'x'. So, fractional abundance of  Li-7 isotope will be '1 - x'

For Li-6 isotope:

Mass of  Li-6 isotope = 6.015 amu

For Li-7 isotope:

Mass of  Li-7 isotope =  7.016 amu

Average atomic mass of lithium =  6.941 amu

6.941 amu = x *(6.015) + (1-x) * (7.016)

x= 0.0749

The relative abundance of Li-6 =0.0749 = 7.49%

The relative abundance of Li-7 =1 - 0.0749 = 0.9251 =92.51%

when this enzyme catalyze the reaction, the activation energy barrier changes by 27.6 kj/mol for the forward rate constant. how will the activation energy barrier change for the reverse rate constant in this catalyzed reaction?

The change in the activation energy barrier is the same: 27.6 kJ/mole.

By reducing the activation energy, a catalyst can speed up a process. In the case of this question, the activation energy is reduced by 27.6 kg per mole, which unquestionably speeds up the reaction.

However, a catalyst does not disrupt the equilibrium because it clearly affects both the forward and backward reaction rates as shown in the picture attached below.

As a result, the forward reaction's activation energy is reduced by 27.6 kJ/mole. Then perhaps the activation energy barrier, 27.6 KJ/mole for the reverse reaction, does not change. Consequently, the addition of a catalyst has no effect on the equilibrium.

Therefore, the activation energy barrier remains constant at 27.6 kJ/mole.

the diagrams above represent two allotropes of solid phosphorus. which of the following correctly identifies the allotrope with the higher melting point and explains why?

Answers

Allotrope 1 has the higher melting point because it lacks the covalent bonds between phosphorus atoms that are present in allotrope 2.

The Melting Point Differences Between Allotropes of Solid Phosphorus

Allotropes of solid phosphorus are different forms of the element which differ in their molecular arrangement and structure. Allotrope 1 is a more stable form and has a higher melting point than that of allotrope 2 due to the absence of covalent bonds between the phosphorus atoms in allotrope 1.

The structure of allotrope 1 is an ordered arrangement in which the phosphorus atoms form a three-dimensional lattice. This lattice structure is held together by strong Van der Waals forces, which are electrostatic attractions between the atoms. This structure is more stable than that of allotrope 2 and has a higher melting point due to the increased strength of the interatomic forces.

In contrast, the structure of allotrope 2 is much less ordered, and the phosphorus atoms are held together by covalent bonds. This structure is not as stable as that of allotrope 1 and has a lower melting point. The covalent bonds between the phosphorus atoms are much weaker than the forces in allotrope 1, and consequently the melting point of allotrope 2 is lower.

Answers

The solubility (in g/l) of caso4(s) in 0.300 m na2so4(aq) at 25°c is 0.016762 g/mol.

Solubility is defined as the maximum amount of a substance in an effort to dissolve in a given quantity of solvent at a special temperature. Solubility is a characteristic asset of a particular solute-solvent combination, and special substances have significantly differing solubilities.

Solubility of CaSO₄; K_sp = 4.93 × 10⁻⁵

Concentration of Na₂SO₄ = 0.4 M

The ionic equation of CaSO₄ is given as;

CaSO₄ ⇒ Ca²⁺ + SO₄²⁻

Now, the formula for solubility ,

K sp = [A⁺]ᵃ × [B⁻]ᵇ

Thus, plugging in relevant values into the solubility equation -

4.93 × 10⁻⁵ = Ca²⁺ × 0.4

Ca²⁺ = ( 4.93 × 10⁻⁵)/0.4

Concentration of Ca²⁺ = 12.325 × 10⁻⁵ M

The molar mass of CaSO₄ =  136 g

how many molecules are there in 360cm3 of nitrogen as r.t.p

Explanation:

I will assume that r.t.p. is supposed to be STP, Standard Temperature and Pressure.  rtp might refer to room temperature and pressue, but no value is given for room temperature, so let's assume standard temperature (0 degrees Celsius).  Here is a marvelous, and useful, property of gasses at STP:  One mole of gas at STP occupies 22.4 liters.  Let's make that a conversion factor:  (1 mole/22.4 liters).

We have the volume of gas at STP:  360 cm^3.  Convert that into liters:

(360cm^3)*(1 ml/cm^3)*(1 liter/1000 ml) = 0.360 liters(L)

Now use the conversion factor from above to convert the volume of gas into moles of gas:

 (0.360L)*(1 mole/22.4 liters) = 0.0161 moles of gas

By definition, 1 mole is 6.02x10^23 particles, or molecules of the gas.

Convert moles of the gas to molecules:

(0.0161 moles)*((6.02x10^23 molecules)/mole) = 9.68x10^21 molecules of nitrogen.

"A scientist uses a submarine to study ocean life. She begins at sea level, which is an elevation of 0 feet. She travels straight down for 90 seconds at a speed of 3.5 feet per second. She then travels directly up for 30 seconds at a speed of 2.2 feet per second. After this 120 second period, how much time, in seconds, will it take for the scientist to travel back to sea level at the submarine's maximum speed of 4.8 feet per second?

Some glucose produced by gluconeogenesis is stored in the body as glycogen. Order the steps of glycogen synthesis. Not all description accurately describe glycogen synthesis; therefore, not all the descriptions will be used. Pyrophosphates converts PPi and water into Pi. Glycogen synthase adds a glucose unit from UDP-glucose to glycogen, producing a a larger glycogen molecule and UDP. Glycogen synthase removes a glucose unit from a glycogen molecule producing a smaller glycogen molecule and UDP.
