Silo measure d 640 grams of sulphur which occupies 540ml of container at 47 degree celsius.find the pressure of the gas.​

Answer:

b

Explanation:

because its the atom of the same element, the no of protons doesn't change but the mass number changes so we can find the mass number by:

(mass number = atomic no/no of protons + no of neutrons)

here;

mass number given = 65

and we know, no of protons = 29

let no of neutrons = x

hence,

65 = 29 + x

x= 65 – 29

x= 36

hence your answer is b

Answer:

48 g S

Explanation:

Step 1: Define

Molar Mass of Sulfur (S) - 32.07 g/mol

Step 2: Use Dimensional Analysis

\(1.5 \hspace{3} mol \hspace{3} S(\frac{32.07 \hspace{3} g \hspace{3} S}{1 \hspace{3} mol \hspace{3} S} )\) = 48.105 g S

Step 3: Simplify

We have 2 sig figs.

48.105 g S ≈ 48 g S

Answer: ν= \(6.01 * 10^{20\) hz

Answer:

c. 1.25 mol

Explanation:

You might find it helpful to sort the information under the equation like a chart. "n" is the symbol for moles.

        2 LiI(aq) + Cl₂(aq) → 2 LiCl(aq) + I₂(s)

n                           ?           2.50 mol

We are looking for the chemical amount of chlorine, or moles of chlorine.

To find the number of moles, you need the mole ratio.

The mole ratio is the same as the coefficients in the equation.

   Cl₂ to LiCl

1 mol to 2 mol

Start with the given moles (2.50 mol for LiCl) and multiply by the mole ratio.

Since we are looking for molCl₂, write molCl₂ on top.

\(n_{Cl_{2}} = 2.50 mol_{LiCl} * \frac{1mol_{Cl_{2}}}{2 mol_{LiCl}}\)            Units for molLiCl cancel out

\(n_{Cl_{2}} = 1.25 mol_{Cl_{2}}\)          <= notice that we keep 3 significant figures

The chemical amount of chlorine is 1.25 mol.

An acid is traditionally considered to be any chemical compound that, when dissolved in water, produces a solution with greater hydronium cation activity than pure water, i.e., a pH less than 7. Both corrosive acids (and also corrosive bases) are capable of destroying skin by catalyzing the hydrolysis of fats, which are chemically esters. Also, when acids attack metals, hydrogen gas is often released.

This is why your lab partner should remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away.

In an equilibrium mixture of 1m each of CO² and H² at 25 degrees, the substance with the highest concentration is CO².

This is because when these two substances are brought together, they will react to form water and Carbon Monoxide (CO). The reaction is exothermic, meaning that energy is released in the form of heat.

This energy will cause the reaction to favor the formation of CO² over H², as H² requires more energy to form. As a result, the equilibrium mixture will have a higher concentration of CO² than H².

A) The value of Ka for the weak acid C₆H₅NH₃⁺ is approximately 5.03 × 10⁻¹¹.

b) The value of Kb for the weak base ClO⁻ is approximately 1.86 × 10⁻⁵.

A) For the weak acid C₆H₅NH₃⁺, the equilibrium expression for Ka is given by: Ka = [C₆H₅NH₂][H₃O⁺] / [C₆H₅NH₃⁺].

[C₆H₅NH₃⁺] = 0.233 M

[C₆H₅NH₂] = 2.3 × 10⁻³ M

[H₃O⁺] = 2.3 × 10⁻³ M

Plugging these values into the Ka expression:

Ka = (2.3 × 10⁻³ M)(2.3 × 10⁻³ M) / (0.233 M)

Ka ≈ 5.03 × 10⁻¹¹

b) For the weak base ClO⁻, the equilibrium expression for Kb is given by: Kb = [OH⁻][HClO] / [ClO⁻].

[OH⁻] = 4.0 × 10⁻⁴ M

[HClO] = 2.38 × 10⁻⁵ M

[ClO⁻] = 0.273 M

Plugging these values into the Kb expression:

Kb = (4.0 × 10⁻⁴ M)(2.38 × 10⁻⁵ M) / (0.273 M)

Kb ≈ 1.86 × 10⁻⁵

Polarity allows water to be a good solvent because of its molecular structure and its ability to form hydrogen bonds.

Water is a polar molecule, meaning it has a partial positive charge at the hydrogen atoms and a partial negative charge at the oxygen atom. This results in an unequal distribution of electron density, creating a dipole moment.

Due to this polarity, water molecules can form strong hydrogen bonds with other polar molecules and ions. These hydrogen bonds enable water to dissolve a wide range of substances, including salts, sugars, and many organic compounds. When a substance dissolves in water, the water molecules surround and interact with the solute particles, causing them to separate and disperse evenly throughout the solution. This process is known as solvation or hydration.

Furthermore, water's polarity allows it to dissolve substances with both ionic and covalent bonds, making it a versatile solvent. Its high dielectric constant also contributes to its ability to stabilize ions in solution, which promotes solubility.

In summary, water's polarity and ability to form hydrogen bonds make it an excellent solvent for many substances. This property is essential for various biological, chemical, and environmental processes that rely on the solubility of compounds in water.

It is important to clean our glass ware immediately after use for a few reasons. Firstly, if left unwashed, the residue left behind by drinks or food can become stubborn stains that are difficult to remove.

This can lead to a build-up of grime and bacteria that could be harmful to our health. Secondly, cleaning glassware immediately after use prevents any odors or flavors from lingering and contaminating the next drink or food that is served in the glass. This is especially important in the case of wine glasses, where any residual wine left in the glass can mix with the next wine and alter its taste. Finally, cleaning glassware immediately after use helps to maintain the integrity of the glass itself. Over time, dirt and grime can cause scratches and weaken the glass, reducing its lifespan. By cleaning glassware immediately after use, we can ensure that it remains in good condition and is able to serve us well for a long time. Therefore, it is always best to clean glassware immediately after use to maintain its cleanliness, prevent contamination, and preserve its quality.

Answer: C

Explanation:

CO2 + H2O = H2CO3

Approximately 35.90 grams of ice must melt to lower the water temperature to 0.0°C.

To solve this problem, we need to calculate the amount of heat that needs to be transferred from the water to the ice in order to lower the water temperature to 0.0°C.

First, let's calculate the initial heat content of the water. The specific heat capacity of water is 4.186 J/(g·K), and the mass of the water can be calculated using its density (1 g/mL) and volume (7.30 × 10^2 mL):

Mass of water = density × volume = 1 g/mL × 7.30 × 10^2 mL = 7.30 × 10^2 g

The initial heat content of the water can be calculated using the formula:

Heat content = mass × specific heat capacity × temperature change

Heat content = 7.30 × 10^2 g × 4.186 J/(g·K) × (25.0°C - 0.0°C) = 7.30 × 10^2 g × 4.186 J/(g·K) × 25.0°C

Next, we need to calculate the amount of heat that needs to be transferred from the water to the ice to lower the water temperature to 0.0°C. This heat transfer occurs during the melting of the ice.

The amount of heat required to melt the ice can be calculated using the formula:

Heat = mass of ice melted × latent heat of fusion

Let's assume that x grams of ice melts. The mass of the ice can be calculated using its density (0.92 g/mL) and volume (same as the volume of water):

Mass of ice = density × volume = 0.92 g/mL × 7.30 × 10^2 mL = 6.716 × 10^2 g

Heat = x g × 333.7 J/g

Now, we need to ensure that the heat transferred from the water to the ice is enough to lower the water temperature to 0.0°C. The heat transferred from the water to the ice is equal to the heat transferred from the water when its temperature drops to 0.0°C:

Heat content of water = Heat transferred to ice

7.30 × 10^2 g × 4.186 J/(g·K) × 25.0°C = x g × 333.7 J/g

Now, we can solve for x:

x = (7.30 × 10^2 g × 4.186 J/(g·K) × 25.0°C) / (333.7 J/g)

x ≈ 35.90 g

Therefore, approximately 35.90 grams of ice must melt to lower the water temperature to 0.0°C.
