Which of the following has the lowest lattice energy? Select the correct answer below: O CaO O ᎡᏏCl Bas O SCP

Answers

Answer 1

The compound with the lowest lattice energy among the options given is CaO.

Lattice energy is a measure of the strength of the electrostatic forces between ions in an ionic compound.

It represents the energy required to separate one mole of a solid ionic compound into its constituent ions in the gas phase.

Among the options given, CaO (calcium oxide) has the lowest lattice energy.

This is because CaO consists of a smaller cation ([tex]Ca^{2+}[/tex]) and a larger anion ([tex]$\mathrm{O^{2-}}$[/tex]).

The smaller the ions and the larger the interionic distance, the weaker the electrostatic forces between them and the lower the lattice energy.

In comparison, NaCl (sodium chloride) has a higher lattice energy because both the sodium ion (Na+) and chloride ion ([tex]$\mathrm{Cl^{-}}$[/tex]) are smaller in size than the calcium and oxygen ions in CaO.

Similarly, BaS (barium sulfide) and SrCl2 (strontium chloride) have higher lattice energies due to the smaller size of their ions.

Therefore, among the options given, CaO has the lowest lattice energy.

There are three main parts to any dissolution which result in an energy change, either endothermic or exothermic. Consider the dissolution of sodium chloride and explain what each of these three major energy changes are.

Answers

Answer:

The dissolution of sodium chloride involves three steps. During the process energy changes occur in:

1. breaking apart the hydrogen bonds between water molecules,

2. breaking apart the electrostatic bonds between sodium and chloride ions, and

3. when bonds are formed between water molecules and aqueous ions in solution.

Since the energy used to break apart the hydrogen bonds between water molecules and the energy used to break apart the electrostatic bonds between sodium and chloride ions, is greater than the energy released when bonds are formed between water molecules and aqueous ions in solution, the dissolution of sodium chloride is endothermic.

Explanation:

The heat of solution or enthalpy of solution/dissolution, is the enthalpy change that occurs with the dissolution of a solute in a solvent at constant pressure, resulting in infinite dilution. Its unit is kJ/mol for reactions taking place under standard conditions (298.15 K and 1 atm).

The process of dissolution occurs in three energy-dependent steps:  

1. The breaking of bonds within the solute. For example, electrostatic forces of attraction between two oppositely-charged ions. This process is endothermic.

2. The endothermic process of breaking of intermolecular forces within the solvent, e.g. hydrogen bonds in water.

3. The exothermic process of the formation of new solute-solvent bonds in solution.

The sum of the energies involved in these three steps gives the enthalpy of dissolution of a solute. The overall process of dissolution can either endothermic or exothermic depending on the amount of energy used or released in breaking and making bonds. If more energy is released in making than is used in breaking bonds, it is exothermic.  However, if more energy is used in breaking bonds than is released in making bonds, dissolution is then endothermic.

For example, considering the dissolution of sodium chloride. During the process the energy used to break apart the hydrogen bonds between water molecules and the energy used to break apart the electrostatic bonds between sodium and chloride ions, is greater than the energy released when bonds are formed between water molecules and aqueous ions in solution. Therefore, the dissolution of sodium chloride is endothermic.

How many moles of Na2SO4 can be made with 7.28 mol of H2SO4?

Answers

Answer:

7.28 mol Na2SO4

Explanation:

Since it is already in moles, all we have to do is use a molar ratio

A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.

7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4

Why is 1/t used as a measure of rate of reaction?​

Answers

1/t denotes that the reaction order is of the first order. That is, the rate of reaction is directly proportional to the concentration of the reactant. Because scientists use standard units, 1/t equals one divided by one second.

What do you mean by first order reaction ?

The term first order reaction is defined as a chemical reaction in which the reaction rate is linearly dependent on the concentration of only one reactant.

In other words, a first-order reaction is a chemical reaction in which the rate varies as the concentration of only one of the reactants changes.

Because a reaction that takes longer to complete is obviously a slower reaction. A fast reaction is one that takes less time to complete. 1/t simply provides a quantitative value for comparing reaction rates.

Thus, 1/t denotes that the reaction order is of the first order.

Limiting reactant - Reactant that can produce a lesser amount of the product

Theoretical yield - Amount of product predicted to be produced by the given reactants

Explanation:

In every chemical reaction, there is a limiting reactant and there is an excess reactant.

The limiting reactant determines the amount of product obtained. It is the reactant that produces a lesser amount of the product.

The excess reactant is known to be the reactant that produces a greater amount of the product.

The theoretical yield is calculated using the limiting reactant and is the amount of product predicted to be produced by the given reactants.

Specific heat capacity of gold (S)

= 0.126 J /kg°C

mass (m) = 350 g = 0.35 kg

difference in temperature (dt)

= 88.5°C - 24.6°C

= 63.9° C

Now

Energy released (Q)

= m*s*dt

= 0.35 * 0.126 * 63.9

25°C?

-
can anyone help me?!!!??!?!​

Answers

Answer:

No, It would be a unsaturated solution

Explanation:

The solubility of a compound gives us information about how a compound may dissolve or not in a determinate solvent.

In this case we have Z, which in 25 °C the solubility of this compound is 40g/100 mL water. This means that if we have 60 g of Z and try to dissolve it in 100 mL of water, only 40 g of Z will solve and the remaining 20 g will be in the water as precipitate or remaining solid.

Now if you just put 40 g of Z in 100 mL water, it will dissolve completely in water, and in this case, we have a saturated solution. A saturated solution is when you dissolve a determinated quantity of a solute in a determinated quantity of solvent, without remaining of solid or excess of solvent.

According to this explanation, we now have 120 g of Z. To make a saturated solution of Z with this quantity, well, let's do math. If 40 g dissolves in 100 mL, then 80 g would be 200 mL and 120 g would have to be 300 mL of water. But in this case, we have 450 mL of water, we have more than 300 mL, an excess of water, so, the 120 g will dissolve but it's dissolved in more than the needed quantity to be a saturated solution, therefore, we have an unsaturated solution of Z (more solvent than the needed).

Hope this helps.

Explanation:

The metathesis rxn, or double replacement rxn, equation is:

(Molarity x Volume) of acid = (Molarity x Volume) of base, or

(M·V)acid = (M·V)base => M(base) = M·V(acid)/V(base)

Answer:

The enthalpy of solution for AgNO3 is positive because the temperature of the solution decreases (the dissolution is endothermic). Hsol = Hsolute + Hsolvent + HmixHsolute and Hsolvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles.

Answer:

the enthalpy of solution for agno3 is positive because the temperature of the solution decreases. (the dissolution is endothermic.)

Delta H sol=delta HSolute +delta H solvent +delta H mix

HSolute and H solvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles.

H mix is exothermic because energy is released when intermolecular forces form between solute and solvent particles.

if the overall enthalpy of solution is positive, then HSolute + H solvent must be larger in magnitude than H mix.
