Answer:

  -172.6 °C

Explanation:

You want to know the Celsius equivalent of the temperature 100.6 K.

The relation is ...

  C = K - 273.15

  C = 100.6 -273.15 = -172.55

The temperature is -172.55 °C, about -172.6 °C.

Additional comment

We have rounded to tenths, because that is precision of the temperature given. If you use 273 as the conversion constant, you will get -172.4.

Answer:

2AlBr₃\(_{aq}\)   +    3Cl₂\(_{g}\)  →    2AlCl₃\(_{aq}\)   + 3Br₂\(_{g}\)

Explanation:

The word equation is:

   Aqueous aluminum bromide and chlorine gas react to form aqueous  aluminum  chloride and bromine gas  

 Reactants:

     aluminum bromide  = AlBr₃

     chlorine gas  = Cl₂

 Products:

      aluminum chloride  = AlCl₃

      bromine gas  = Br₂  

So;

        2AlBr₃\(_{aq}\)   +    3Cl₂\(_{g}\)  →    2AlCl₃\(_{aq}\)   + 3Br₂\(_{g}\)

Given that the radius of a silver atom is 145 pm, it would take \(7.97 \times 10^{6}\) silver atoms laid side by side to span a distance of 2.31 mm.

The radius of a silver atom is 145 pm. Then, the diameter (twice the radius) is:

\(d = 2 \times 145 pm = 290 pm\)

We will convert 290 pm to millimeters. We will use the conversion factors:

\(290 pm \times \frac{1m}{10^{12}pm } \times \frac{10^{3}mm }{1m} = 2.90 \times 10^{-7} mm\)

If the diameter of 1 silver atom is 2.90 × 10⁻⁷ mm, the number of silver atoms required to span a distance of 2.31 mm is:

\(2.31 mm \times \frac{1Ag\ atom}{2.90 \times 10^{-7}mm } = 7.97 \times 10^{6} Ag\ atom\)

\(7.97 \times 10^{6}\) silver atoms span a distance of 2.31 mm.

1)The new volume at a pressure of 1 atm is 0.25 L.

2)The new temperature of the container at a volume of 2 L is approximately 398°C.

3)The new pressure at 2.5 L is approximately 4.8 atm.

4)The new volume at a temperature of 60°C is approximately 55.8

1)To solve these gas law problems, we can use the ideal gas law equation, which states:

PV = nRT,

where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature in Kelvin.

Balloon volume at a pressure of 0.5 atm:\(V_1\) = 0.5 L, \(P_1\)= 0.5 atm.

New volume at a pressure of 1 atm:\(P_2\) = 1 atm.

We can use the relationship\(P_1V_1 = P_2V_2\) to find the new volume (\(V_2\)).

(0.5 atm)(0.5 L) = (1 atm)(\(V_2\))

\(V_2\) = 0.25 L.

Therefore, the new volume at a pressure of 1 atm is 0.25 L.

2)Container volume: \(V_1\) = 2 L, \(T_1\)= 125°C.

New temperature at the same volume: \(V_2\) = 2 L.

We can use the relationship\(V_1\)/\(T_1\) = \(V_2\)/\(T_2\) to find the new temperature (\(T_2\)).

(2 L)/(125 + 273) K = (2 L)/(\(T_2\) + 273) K

Solving for\(T_2\), we get \(T_2\) ≈ 398°C.

Therefore, the new temperature of the container at a volume of 2 L is approximately 398°C.

3)Initial volume: \(V_1\)= 4.0 L, \(P_1\) = 3.0 atm.

Final volume: \(V_2\) = 2.5 L.

Since the temperature (T) is constant, we can use the relationship \(P_1\)\(V_1\) = \(P_2V_2\) to find the new pressure (\(P_2\)).

(3.0 atm)(4.0 L) = (\(P_2\))(2.5 L)

\(P_2\) ≈ 4.8 atm.

Therefore, the new pressure at 2.5 L is approximately 4.8 atm.

4)Initial volume: \(V_1\)= 50 mL, \(T_1\) = 25°C.

New temperature: \(T_2\) = 60°C.

We need to convert the temperatures to Kelvin.

\(T_1\)= 25 + 273 = 298 K, \(T_2\) = 60 + 273 = 333 K.

We can use the relationship \(V_1/T_1 = V_2/T_2\) to find the new volume (\(V_2\)).

(50 mL)/(298 K) = (\(V_2\))/(333 K)

\(V_2\) ≈ 55.8 mL.

Therefore, the new volume at a temperature of 60°C is approximately 55.8

Answer:

7.5 kcal

Explanation:

1.0 cal /g-C   * 100 g * (100- 25 C) = 7500 cal = 7.5 kcal

The amount of heat energy necessary to raise the temperature of 100 g of water at room temperature (25°C) to the boiling point (100°C) is 7.5 kcal.

Given to us the mass of water, the specific heat of water, and the change in temperature, we need to calculate the amount of heat energy.

m = 100 g

c = 1.0 cal/g°C

ΔT = (100 °C - 25 °C) = 75 °C

To calculate the amount of heat energy required, we can use the formula:

Q = m × c× ΔT

Where:

Q = heat energy (in calories)

m = mass of water (in grams)

c = specific heat of water (in cal/g°C)

ΔT = change in temperature (in °C)

Substituting the values into the formula:

Q = 100 g × 1.0 cal/g°C × 75 °C

Q = 7500 cal

7500 cal = 7.5 kcal

Therefore, the amount of heat energy required to raise the temperature of 100 g of water from 25 °C to 100 °C is 7500 calories, which is equivalent to 7.5 kcal.

The volume of chlorine molecules produced at STP would be 96 dm³.

Sodium chloride ionizes during electrolysis to produce sodium and chlorine ions as follows:

\(NaCl --- > Na^+ + Cl^-\)

This means that 1 mole of sodium chloride will produce 1 mole of sodium ion and 1 mole of chlorine ion respectively.

Recall that: mole = mass/molar mass

Hence, 234 g of sodium chloride will give:

                         234/58.44 = 4.00 moles.

Thus, the equivalent number of moles of chlorine produced by 234 g of sodium chloride will be 4 moles.

Recall that:

1 mole of every gas at Standard Temperature and Pressure = 24 Liters.

Hence:

4 moles of chlorine = 4 x 24 = 96 Liters or 96 dm³.

Answer: it's k

Explanation:

Same reason as the person above me

The order of the alternatives from largest to lowest atomic radius is K > Na > \(\rm Na^+\) > \(\rm K^+\).

The atomic radius usually decreases from left to right across the periodic table due to increasing effective nuclear charge, which attracts electrons more strongly and reduces the atomic radius. As a result, among the options offered K (potassium) has the largest atomic radius. Because the atomic radius shrinks from left to right, K (potassium) has a larger atomic radius than Na (sodium).

In addition, when an atom loses an electron to become an ion, its radius decreases. As a result, the \(\rm Na^+\) ion has a smaller radius than Na. The radius of potassium ion is greater than that of sodium ion because potassium is in the same period as sodium but is one group to the left, resulting in a larger atomic radius.

Explanation:

First, add together the moles of the two samples:

5.25 moles + 4.20 moles = 9.45 moles

273 + 25 = 298 K for the temperature

volume is 10.0 L

Since we have moles now, we have to rearrange our ideal law equation to solve for pressure:

\(P = \frac{nRT}{V}\)

\(\frac{(9.45 moles) X (0.08206) X (298 K)}{10.0 L}\)

9.45 X .08206 X 298 all divided by 10.0 = 23.09202 atm (or 23.12)

One can change the concentration of a solution while keeping the number of moles of solute the same by reducing the volume of solvent in the solution.

The molarity of a solution is the number of moles of solute per unit volume of solvent.

The number of moles of solute in a unit volume of solvent can be kept constant while the volume of the solvent reduced in order to increase the concentration of a solution.

For example, a solution with 2 moles of solute in 1 L of solvent will have a molarity of 2 M.

If the amount of solvent is reduced to 0.5 L, the molarity will become:

The final temperature of the mixture given that 25 g of water at 25 °C is mixed with 25 g of water at 65 °C, is 45 °C

The final temperature of the mixture can be obtained by calculating the equilibrium temperature of the mixture. This is shown below:

Heat loss by warm water = Heat gain by cold water

MᵥᵥC(Tᵥᵥ - Tₑ) = MC(Tₑ - T)

Cancel out C

Mᵥᵥ(Tᵥᵥ - Tₑ) = M(Tₑ - T)

25× (65 - Tₑ) = 25 × (Tₑ - 25)

Cancel out 25

65 - Tₑ = Tₑ - 25

Collect like terms

65 + 25 = Tₑ + Tₑ

90 = 2Tₑ

Divide both side by 2

Tₑ = 90 / 2

Tₑ = 45 °C

The volume of the alcohol can be obtained as 79.9 mL.

We know that there are many different unit of concentration. The unit of concentration that we are going to focus on here is the volume per volume percent. This has to do with the volume of solute in a given volume of the solvent.

Thus we have;

Volume solution = 355 mL

Volume percent of the alcohol =  22.5%

Actual volume of the alcohol = x

We now have;

Volume percent = Volume of the alcohol (x)/volume of the solution * 100/1

22.5 = x/355 * 100/1

Hello there!

\(NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O\)

Which must be balanced according to the law of conservation of mass:

\(2NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O\)

Whereas there is a 2:1 mole ratio of NaOH to Cl2, which means that the moles of the former that are consumed by 0.85 moles of the latter are:

\(n_{NaOH}=0.85molCl_2*\frac{2molNaOH}{1molCl_2}\\\\n_{ NaOH}=1.7molNaOH\)

Therefore, since we just have 1.23 moles out of 1.70 moles of NaOH, we infer this is the limiting reactant.
