Explanation:

To determine the number of particles in 65 grams of potassium iodide (KI), we need to use the Avogadro's constant (NA) and the molar mass of KI.

The molar mass of KI can be calculated by adding the atomic masses of potassium (K) and iodine (I) in one KI molecule. The atomic masses of K and I are 39.10 g/mol and 126.90 g/mol, respectively. Therefore, the molar mass of KI is:

Molar mass of KI = atomic mass of K + atomic mass of I

= 39.10 g/mol + 126.90 g/mol

= 166.00 g/mol

Now we can calculate the number of particles in 65 grams of KI using the following formula:

Number of particles = (mass of sample / molar mass) x Avogadro's constant

Number of particles = (65 g / 166.00 g/mol) x 6.022 x 10^23 particles/mol

= 2.51 x 10^23 particles

Therefore, there are approximately 2.51 x 10^23 particles in 65 grams of potassium iodide (KI).

To find the total number of valence electrons in the molecule XeBr₂Cl₂, you'll need to consider the valence electrons of each element in the compound. The elements are Xenon (Xe), Bromine (Br), and Chlorine (Cl).

1. Xenon (Xe) has 8 valence electrons, as it is in Group 18 of the periodic table.
2. Bromine (Br) has 7 valence electrons, as it is in Group 17. Since there are two Bromine atoms in the compound (Br₂), you'll need to multiply 7 by 2, which equals 14.
3. Chlorine (Cl) also has 7 valence electrons, as it is in Group 17 as well. Since there are two Chlorine atoms in the compound (Cl₂), you'll need to multiply 7 by 2, which equals 14.

Now, add the valence electrons of all the elements in the compound:
Total valence electrons = Valence electrons of Xe + Valence electrons of Br₂ + Valence electrons of Cl₂
Total valence electrons = 8 + 14 + 14

The total number of valence electrons in the molecule XeBr₂Cl₂ is 36.

There are approximately 32.89 grams of sodium in a 120-gram sample of NaHCO3.

The molar mass of NaHCO3 (sodium bicarbonate) can be calculated by adding up the atomic masses of its constituent elements:

NaHCO3 = 1Na + 1H + 1C + 3O

Molar mass of NaHCO3 = 23.0 g/mol + 1.0 g/mol + 12.0 g/mol + (3 × 16.0 g/mol) = 84.0 g/mol

This means that one mole of NaHCO3 has a mass of 84.0 grams.

To determine the number of moles of NaHCO3 in a 120-gram sample, we can use the following equation:

Since the ratio of Na to NaHCO3 is 1:1, there are also 1.43 moles of Na in the sample.

Finally, we can calculate the mass of sodium (Na) in the sample by multiplying the number of moles of Na by its atomic mass:

mass of Na = moles of Na × atomic mass of Na

mass of Na = 1.43 mol × 23.0 g/mol

mass of Na = 32.89 g

Therefore, there are approximately 32.89 grams of sodium in a 120-gram sample of NaHCO3.

Answer:

Explanation: Take, for example, an ice cube in an open or closed container, that is in the process of melting at room temperature. There is solid water, liquid water, and water vapour (gas) in the air.

Answer:

An endothermic reaction takes in heat, but feels cold to the touch. An exothermic reaction gives off heat and feels warm to the touch because it is heating the outside objects.

1. The total distance traveled by the car is 223.61 km

2. The total displacement traveled by the car is 223.61 km south east

The total distance traveled by the car can be obtained as shown below:

Total distance traveled =  √(d₁²+ d₂²)

Total distance traveled = √(200² + 100²)

Total distance traveled = √(4000 + 1000)

Total distance traveled = √50000

Total distance traveled = 223.61 km

Displacement is the distance traveled in specific direction.

From the above calculation, we can see that the total distance traveled is 223.61 km.

Also, we can see from the question given above that the car started from east and move towards the south.

Thus, we can conclude that the total displacement of the car is 223.61 km south east

After two or more atoms lose or receive electrons to create an ion, an ionic bond can occur. Ionic bonds form when metals lose electrons and nonmetals acquire electrons. Ions with opposing charges attract one other, forming an ionic connection.

Ionic bonding is the principal interaction in ionic compounds and includes the electrostatic attraction between oppositely charged ions or between two atoms with drastically differing electronegativities. Ionic bond, also known as electrovalent bond, is a kind of connection generated in a chemical molecule by the electrostatic attraction of oppositely charged ions. When the valence (outermost) electrons of one atom are permanently transferred to another, a bond is formed.

When two surface come in contact and rub each other a frictional force causing them s deformation and this leads to a voltage giving rise to a static charge.

Static charge is developed within a body temporarily with an induced polarization. These charges are not moving and set into a pole in the material.

When two materials rub against each other in which one is a conductor and other to be an insulator, they will attract by the induced polarization. Rubbing causes the free electrons in the condutor to be transferred towards the insulator.

This will cause a deformation that, the random charges in the material get polarized where the electrons in the insulator will repel to the opposite pol and positive charges will align in a pole close to the condutor.

This charge separation causes the positive pole of the insulator gets attracted into the conductor surface. Hence, there forms a static electricity by the passage of electron.

When a thermal energy is applied to a container of gas the volume of the gas will increase

Heating a gas makes its atoms and molecules move faster and that way increases the kinetic energy of the particles causing the gas expansion and the increase of its volume and pressure.

Otherwise when the thermal energy is removed, the atoms or molecules start to move slower and become denser until the substance condenses.

Common examples of  kinetic energy due to thermal energy are: rubbing the hands, baking in an oven, boiling water, when the seat of the car are heated.

The pH of the solution after the addition of 450 ml of 0.10 M NaOH to a 450 ml sample of 0.20 M HF can be determined by considering the reaction between HF (a weak acid) and NaOH (a strong base) and calculating the resulting concentration of the conjugate base.

HF (hydrofluoric acid) is a weak acid, and NaOH (sodium hydroxide) is a strong base. When these two substances react, they undergo a neutralization reaction to form water and the conjugate base of HF, which is F⁻ (fluoride ion).

The balanced chemical equation for the reaction is:

HF + NaOH → H2O + NaF

Given that the initial volume of both the HF solution and NaOH solution is 450 ml and their concentrations are 0.20 M and 0.10 M, respectively, we can use the concept of stoichiometry to determine the concentration of F⁻ (fluoride ion) in the final solution.

Since the moles of HF and NaOH are equal in the reaction (1:1 ratio), when 450 ml of 0.10 M NaOH is added to 450 ml of 0.20 M HF, the concentration of F⁻ can be calculated as follows:

Initial moles of HF = 0.20 M * 0.450 L = 0.090 moles

Moles of F⁻ = 0.090 moles

Total volume of the final solution = 450 ml + 450 ml

= 900 ml

= 0.900 L

Concentration of F⁻ = Moles of F⁻ / Total volume

Concentration of F⁻ = 0.090 moles / 0.900 L

Concentration of F⁻ = 0.10 M

Since F⁻ is the conjugate base of HF, we can consider the dissociation of F⁻ as a hydrolysis reaction. The F⁻ ion reacts with water to form OH⁻ ions:

F⁻ + H2O → HF + OH⁻

Since the concentration of F⁻ is 0.10 M, the concentration of OH⁻ ions is also 0.10 M. Now, we can use the fact that pOH + pH = 14 to calculate the pH of the solution:

pOH = -log10[OH⁻]

pOH = -log10[0.10]

pOH≈ 1

pH = 14 - pOH

pH = 14 - 1

pH = 13

Therefore, the pH of the solution after the addition of 450 ml of 0.10 M NaOH to a 450 ml sample of 0.20 M HF is approximately 13. The hydrolysis of the fluoride ion (F⁻) formed in the reaction between HF and NaOH leads to the presence of hydroxide ions (OH⁻) in the solution, resulting in a high pH value.

To determine the minimum volume of distilled water required to completely dissolve a 3.0 g sample of CuCO3 (copper carbonate) at 25°C, we need to consider the solubility of copper carbonate in water at that temperature.

The solubility of copper carbonate in water can vary with temperature. At 25°C, the solubility of copper carbonate is approximately 0.0013 g/100 mL. This means that for every 100 mL of water at 25°C, approximately 0.0013 g of copper carbonate can dissolve.

Now, we can set up a proportion to calculate the volume of water required:

(0.0013 g / 100 mL) = (3.0 g / x mL)

Cross-multiplying and solving for x, we get:

x = (3.0 g * 100 mL) / 0.0013 g

x ≈ 230,769 mL

Therefore, the minimum volume of distilled water needed to completely dissolve a 3.0 g sample of CuCO3 at 25°C is approximately 230,769 mL or 230.769 L.

Answer:

 A.    2Na       +    2H₂O   →    2NaOH   +  H₂  

Explanation:

When sodium is reacted with water, a single replacement reaction occurs. The product of the reaction is typically sodium hydroxide and hydrogen gas.

Reactants:

        Sodium +  water

Product:

        Sodium hydroxide + hydrogen gas

So;

         2Na       +    2H₂O   →    2NaOH   +  H₂  

One of the products of this reaction is solid tin(II) carbonate (SnCO₃).

When aqueous sodium carbonate (Na₂CO₃) reacts with aqueous tin(II) nitrate (Sn(NO₃)₂), a double-replacement reaction takes place. The balanced chemical equation for the reaction is,

Na₂CO₃(aq) + Sn(NO₃)₂(aq) → SnCO₃(s) + 2NaNO₃(aq)

In this reaction, the sodium ion and nitrate ion from the sodium carbonate and tin(II) ion and nitrate ion from the tin(II) nitrate switch places to form solid tin(II) carbonate and aqueous sodium nitrate.

What is specific heat capacity?

 This refers to the amount of heat in joules (J) absorbed per unit mass (kg) of the material when its temperature rises 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

From the question:

cp= 0.20 cal/(g°C)

T = 150°C

heat added = 30 cal

To find the mass of the glass, you can use the formula:

mass = heat added / (specific heat capacity x temperature change)

Substituting the given values:

mass =           30 cal

              (0.20 cal/(g°C) x 150°C)

mass =             30

                 (0.20 x 150)

mass       = 30
