Energy is released during which phase changes

Answers

Answer 1
I think the phase changes that involves the release of energy is  change from Liquid to solid and also change from gas to liquid. The latent heat of fusion involves energy flow during the change of phase from solid to liquid. This change is endothermic, which means the system absorbs energy on going from solid to liquid, however when the direction is from liquid to solid the change would be exothermic. The same happens when we talk about latent heat of vaporization where change of phase from liquid to gas is endothermic, and the change form gas to liquid is exothermic.

If 20.60 ml of 0.0100 m aqueous hcl is required to titrate 30.00 ml of an aqueous solution of naoh to the equivalence point, what is the molarity of the naoh solution?

Answers

the balanced equation for the above reaction is as follows;
NaOH + HCl -- > NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
number of HCl moles reacted - 0.0100 mol/L x 0.02060 L = 0.000206 mol 
according to 1:1 molar ratio
number of NaOH moles reacted - 0.000206 mol 
number of NaOH moles in 30.00 mL - 0.000206 mol 
therefore number of NaOH moles in 1000 mL - 0.000206 mol / 0.03000 L = 0.00687 mol
molarity of NaOH is 0.00687 M

Answer : The molarity of the NaOH solution is, 0.00687 M.

Explanation :

The balanced chemical reaction will be:

[tex]HCl+NaOH\rightarrow NaCl+H_2O[/tex]

Given the equation zn(s) + 2 hcl(aq) → zncl2(aq) + h2(g), what mass of hydrogen gas is produced when 2.8 g zn is reacted with excess aqueous hydrocholric acid?

Answers

Final answer:

To calculate the mass of hydrogen gas produced, we use stoichiometry of the chemical reaction between Zn and excess HCl. After determining moles of Zn from the given mass, we find the moles of H2, which is equal due to the 1:1 molar ratio, and then multiply by the molar mass of H2 to get 0.0863 g of hydrogen gas.

Explanation:

Calculating the Mass of Hydrogen Gas

To calculate the mass of hydrogen gas produced when 2.8 g of Zn is reacted with excess hydrochloric acid (HCl), we will use the stoichiometry of the balanced chemical reaction: Zn(s) + 2 HCl(aq) → ZnCl₂ (aq) + H₂(g). The reaction shows that one mole of Zn produces one mole of H2. First, we find the molar mass of Zn, which is approximately 65.38 g/mol.

Step 1: Calculate the moles of Zn.

Moles of Zn = (mass of Zn) / (molar mass of Zn) = 2.8 g / 65.38 g/mol = 0.0428 mol

Step 2: Determine the moles of H2 formed using the molar ratio from the balanced equation (1:1).

Moles of H2 = Moles of Zn = 0.0428 mol

Step 3: Calculate the mass of H2 using the molar mass of H2 (approximately 2.016 g/mol).

Mass of H2 = Moles of H2 × Molar mass of H2 = 0.0428 mol × 2.016 g/mol = 0.0863 g

Therefore, the mass of hydrogen gas produced is 0.0863 g.

A solution mass of 1 kg is ___ times greater than 100 g, thus one kilogram (1 kg) of a 2.5% ki solution would contain _____ of ki.

Answers

The answer is "A solution mass of 1 kg is 10 times greater than 100 g, thus one kilogram (1 kg) of a 2.5% KI solution would contain 25 grams of KI."
A 2.5% by mass KI solution is equivalent to 2.5 grams of KI divided by 100 grams of the KI solution and then multiply by 100. We can multiply 10 to the masses of the solute and the solution so that 100 grams becomes 1000 grams.      
     2.5% by mass = (mass of solute / mass of solution) *100
                             = [(2.5g*10) / (100g*10)] *100
                             = (25g solute/1000g solution) *100
Since 1000 grams is equal to 1 kg, the expression becomes
     2.5% by mass = (25g solute/1kg solution) *100
Therefore, 2.5% by mass KI solution would contain 25 grams KI in 1 kilogram solution.

A 1 kg solution is 10 times greater than 100 g, and a 2.5% KI solution with a mass of 1 kg would contain 25 g of KI.

A solution mass of 1 kg is 10 times greater than 100 g. To determine the amount of potassium iodide (KI) in a 2.5% KI solution with a total mass of 1 kg, we can calculate the mass of the solute (KI) by using the percent by mass formula:

Percent by mass = (Mass of solute / Mass of solution) x 100

In this case, the mass of the solute is 2.5% of 1 kg, which can be calculated as follows:

Mass of KI = 0.025 x 1 kg = 0.025 kg or 25 g

This means that a 1 kg solution containing a 2.5% KI would have 25 g of potassium iodide.

Which substance would be least likely to dissolve in a polar solvent?

Answers

Final answer:

Octane (C8H18) and naphthalene are nonpolar substances and would be least likely to dissolve in a polar solvent like water. Methanol (CH3OH), sodium sulfate (Na2SO4), LiCl, and benzoic acid (CH2CO2H) are polar or ionic and would more readily dissolve.

Explanation:

To predict which substance would be least likely to dissolve in a polar solvent like water, one must consider the polarity of the molecules involved. In general, "like dissolves like," which means that polar solvents will dissolve polar substances and nonpolar solvents will dissolve nonpolar substances.

Methanol (CH3OH) and sodium sulfate (Na2SO4) are polar and will likely dissolve in water due to their ability to create intermolecular hydrogen bonds and ionic interactions, respectively. On the other hand, octane (C8H18) is nonpolar, consisting mostly of C-H bonds, and would have the least tendency to dissolve in a polar solvent due to dispersion forces being the primary intermolecular interaction.

Considering LiCl, benzoic acid (CH2CO2H), and naphthalene, LiCl and benzoic acid are more likely to dissolve in water due to their ionic and polar nature, respectively, while naphthalene, being nonpolar, would be the least likely to dissolve.

Which will dissolve faster in water one gram cube of sugar or one gram of powder sugar?

Answers

the  powder sugar because has more contact area 

Powdered sugar dissolves faster than a cube of sugar because it has a greater surface area, which increases the frequency of collisions between the sugar particles and water molecules, hence speeding up the dissolving process.

In the comparison of a one gram cube of sugar and one gram of powdered sugar dissolving in water, the powdered sugar will dissolve faster. This phenomenon is because dissolving is a surface-driven process where solvent molecules collide with the surface of the solute.

The powdered sugar has a greater surface area exposed to the water, increasing the opportunity for these collisions to occur, which enhances the rate of dissolution. Moreover, stirring the solution can increase the rate at which both the powdered and the cube sugar dissolve. However, since the cube has less surface area exposed compared to powdered sugar, the powdered form will still dissolve more quickly, even with agitation.

The speed at which the sugar dissolves isn't dependent on the type of sugar since both forms have the same chemical composition, but rather on the physical form of the sugar which affects the overall surface area available for dissolution.

To solve these types of problems, we use Avogadro's number (6.02 × 10²³), which is the number of units in one mole of any substance. This can be atoms, ions, or molecules, depending on the context of the substance in question.

Answers:

There are 6.02 × 10²³ atoms of zinc in 0.60 mol of zinc.To find how many moles 3.52 × 10²⁴ molecules of water represents, divide by Avogadro's number: 3.52 × 10²⁴ molecules ÷ (6.02 × 10²³ molecules/mol) ≈ 5.84 mol of water.For lithium, there are 2 × 6.02 × 10²³ atoms in 2.00 moles of Li, since 1 mol of any element contains exactly 6.02 × 10²³ atoms by definition.Having 6.02 × 10²³ atoms of carbon means you have 1 mole of carbon, as 1 mol is equivalent to Avogadro's number of atoms.To determine the number of moles in 4.9 × 10²³ molecules of ZnCl₂, divide by Avogadro's number: 4.9 × 10²³ molecules ÷ 6.02 × 10²³ molecules/mol ≈ 0.814 mol of ZnCl₂.

This is the uneven distribution of bonding electrons in a molecule creating partially positive and negative sides of that molecule. example: water and ammonia have this, but methane does not

Answers

Following are the molecules of interest H2O, NH3 and CH4.

In each of the above system, central element undergoes sp3 hybridization.

For example, in H2O, oxygen undergoes sp3 hydridization
in case of NH3, nitrogen underdoes sp3 hybridization,
and in case of CH4, methane undergoes sp3 hydridization.

Followed by hybridization, the hybridized orbitals are unsymmetrically occupied in case of H2O and NH3. In water, two hybridized  orbitals are occupied by H atom and remaining two orbitals contain lone pair of electrons. In case of NH3, three hybridized orbitals are utilized for bonding with H atom, while one hybridized orbital contain lone pair of electron. In contrast to this, in case of methane all the four hybridized orbitals are utilized for bonding with hydrogen. Thus, methane is symmetrically substituted in contrast to water and ammonia. Due to this,  there is the uneven distribution of bonding electrons in H2O and NH3, thereby creating a partially positive and negative sides of that molecule. 

The poh of a solution is 9.32. calculate the hydrogen ion concentration of the solution.

Answers

Final answer:

To find the hydrogen ion concentration from the pOH value of 9.32, we first calculate the pH as 4.68. We then use the relationship [H3O+] = 10^-pH to find the hydronium ion concentration, which is approximately [tex]2.09 × 10^-5 M.[/tex]

Explanation:

The student asked about calculating the hydrogen ion concentration of a solution from its pOH. The pOH of a solution is 9.32, and we want to find the [H3O+]ion concentration, also written as [H+].

The relationship between pH, pOH, and ion concentrations in water at 25 °C is given by the equation:

pH + pOH = 14

From the given pOH value, we can find the pH:

pH = 14 - pOH

pH = 14 - 9.32 = 4.68

Once we have the pH, we can calculate the hydronium ion concentration using the inverse of the logarithmic relationship:

[H3O+] = 10-pH

[H3O+] = 10-4.68

The final hydrogen ion concentration, or hydronium ion concentration, is therefore approximately 2.09 × 10-5 M.

9 = x2 

y-coordinate of midpoint = (y1 + y2)/2 
3 = (-5 + y2)/2 
6 = -5 + y2 
11 = y2 

Final answer:

The coordinates of the other endpoint, H, can be calculated using the midpoint formula: Endpoint = (2 x Midpoint) - Known Endpoint. Applying this formula, we find that the coordinates of endpoint H are (9, 11).

Explanation:

The subject of this question is Mathematics, specifically coordinate geometry. Given the midpoint M(5,3) and one endpoint G(1,-5), we're asked to find the coordinates of the other endpoint, H. The formula to find the coordinates of an endpoint when given the midpoint and another endpoint is as follows:
