What mass of water in grams will fill a tank 126cm long, 47 cm wide, and 13 cm high

Answer: \(CaCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+CaCO_3(s)\)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The balanced reaction between aqueous calcium chloride reacts with aqueous potassium carbonate is shown as:

\(CaCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+CaCO_3(s)\)

The empirical formula of the compound is C₂H₁₆S₂N₃O.

The moles of each element is as follows::

For CO₂:

Carbon (C) has a molar mass of 12.01 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of C in CO₂ = 2.08 g / 12.01 g/mol = 0.173 moles

Moles of O in CO₂ = 2.08 g / 16.00 g/mol = 0.130 moles

For H₂O:

Hydrogen (H) has a molar mass of 1.01 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of H in H₂O = 1.28 g / 1.01 g/mol = 1.27 moles

Moles of O in H₂O = 1.28 g / 16.00 g/mol = 0.080 moles

For SO₃:

Sulfur (S) has a molar mass of 32.06 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of S in SO₃ = 4.77 g / 32.06 g/mol = 0.149 moles

Moles of O in SO₃ = 4.77 g / 16.00 g/mol = 0.298 moles

For HNO₃:

Hydrogen (H) has a molar mass of 1.01 g/mol.

Nitrogen (N) has a molar mass of 14.01 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of H in HNO₃ = 3.48 g / 1.01 g/mol = 3.45 moles

Moles of N in HNO₃ = 3.48 g / 14.01 g/mol = 0.248 moles

Moles of O in HNO₃ = 3.48 g / 16.00 g/mol = 0.217 moles

The simplest whole-number ratio of the elements will be:

Carbon: 0.173 moles / 0.080 moles ≈ 2.16

Hydrogen: 1.27 moles / 0.080 moles ≈ 15.88

Sulfur: 0.149 moles / 0.080 moles ≈ 1.86

Nitrogen: 0.248 moles / 0.080 moles ≈ 3.10

Oxygen: 0.080 moles / 0.080 moles = 1

Therefore, the empirical formula is C₂H₁₆S₂N₃O.

Answer:

The answer is  D

Explanation:

The molecular formula of the compound containing 81.82% carbon

and 18.18% hydrogen by mass is C₃H₈

From the question given above, the following data were obtained:

Carbon (C) = 81.82%

Hydrogen (H) = 18.18%

Molar mass of compound = 44 g/mol

We'll begin by calculating the empirical formula of the compound. This can be obtained as follow:

Carbon (C) = 81.82%

Hydrogen (H) = 18.18%

Divide by their molar mass

C = 81.82 / 12 = 6.818

H = 18.18 / 1 = 18.18

Divide by the smallest

C = 6.818 / 6.818 = 1

H = 18.18 / 6.818 = 2.67

Multiply by 3 to express in whole number

C = 1 × 3 = 3

H = 2.67 × 3 = 8

Thus, the empirical formula of the compound is C₃H₈

Finally, we shall determine the molecular formula of the compound. This can be obtained as follow:

Molecular formula = Empirical formula × n = molar mass

[C₃H₈]n = 44

[(12×3) + (1×4)]n = 44

[36 + 4]n = 44

40n = 44

Divide both side by 40

n = 44/40

n ≈ 1

Molecular formula = C₃H₈ × n

Molecular formula = C₃H₈ × 1

Therefore, the molecular formula of the compound is C₃H₈

Diagram A: Balanced Forces

These forces are balanced, so the motion of the object stays the same. The object in the diagram could be sitting still, or it could be moving. But its motion is not changing. This is because the forces acting on it from opposite sides are exactly the same size.

Explanation:

Answer:

Because a balanced force can keep an object moving at a constant velocity.

Explanation:

The rate of the given reaction is 0.00197 M/s.

The balanced chemical equation of the reaction is:

CO (g) + NO₂ (g) → CO₂ (g) + NO (g)

From the equation, 1 mole of CO produces 1 mole of CO₂, and hence the number of moles of CO2 produced is equal to the number of moles of CO consumed.

The concentration of CO₂ produced = 0.123 M.

Therefore, the concentration of CO consumed is also 0.123 M.

The rate of reaction is given by the formula:

where Δ[C] is the change in concentration and Δt is the change in time.

Over 62.3 seconds, the concentration of CO decreases from 0 M to 0.123 M.

Δ[C] = 0.123 M - 0 M

Δ[C]  = 0.123 M

Δt = 62.3 s

Substituting the values in the formula, we get:

rate of the reaction = Δ[C]/Δt

rate of the reaction = 0.123 M/62.3 s

rate of the reaction = 0.00197 M/s

Answer:

The assumption that accounts for the great compressibility of gases compared to liquids and solids is assumption 1: Gases are made up of molecules which are relatively far apart. Option A)

The assumption that accounts for the great compressibility of gases compared to liquids and solids is assumption 1: Gases are made up of molecules which are relatively far apart.

In gases, the molecules are widely spaced and have significant gaps between them. This allows gases to be easily compressed under pressure. When external pressure is applied to a gas, the molecules can be brought closer together, reducing the volume occupied by the gas. The gaps between the molecules provide room for compression, allowing gases to occupy a smaller volume.

In contrast, liquids and solids have molecules or particles that are closely packed together. The intermolecular forces in liquids and solids are stronger, limiting their compressibility. The molecules or particles are already in close proximity, leaving little room for further compression.

Therefore, the assumption that gases consist of molecules that are relatively far apart accounts for their greater compressibility compared to liquids and solids. Hence Option A) is correct.

Answer:

0.0104 moles of gas in the flask.

Explanation:

To calculate the number of moles of gas in the flask, you can use the ideal gas law equation: PV = nRT. Where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant and T is temperature.

First, you need to convert the pressure from mmHg to atm and the temperature from Celsius to Kelvin. The pressure in atm is 760.0 mmHg / 760 mmHg/atm = 1 atm. The temperature in Kelvin is 17.00°C + 273.15 = 290.15 K.

Next, you need to convert the volume from mL to L. The volume in L is 250.0 mL / 1000 mL/L = 0.2500 L.

Now you can plug all the values into the ideal gas law equation and solve for n: (1 atm)(0.2500 L) = n(0.08206 L·atm/mol·K)(290.15 K). Solving for n gives n = 0.0104 mol.

So there are approximately 0.0104 moles of gas in the flask.
