The question is missing parts. The complete question is as follows.

Consider the two gaseous equilibria involving SO2 and the corresponding equilibrium constants at 298K:

\(SO_{2}_{(g)} + \frac{1}{2}O_{2}\) ⇔ \(SO_{3}_{(g)}\); \(K_{1}\)

\(2SO_{3}_{(g)}\) ⇔ \(2SO_{2}_{(g)}+O_{2}_{(g)}; K_{2}\)

The values of the equilibrium constants are related by:

a) \(K_{1}\) = \(K_{2}\)

b) \(K_{2} = K_{1}^{2}\)

c) \(K_{2} = \frac{1}{K_{1}^{2}}\)

d) \(K_{2}=\frac{1}{K_{1}}\)

Answer: c) \(K_{2} = \frac{1}{K_{1}^{2}}\)

Explanation: Equilibrium constant is a value in which the rate of the reaction going towards the right is the same rate as the reaction going towards the left. It is represented by letter K and is calculated as:

\(K=\frac{[products]^{n}}{[reagents]^{m}}\)

The concentration of each product divided by the concentration of each reagent. The indices, m and n, represent the coefficient of each product and each reagent.

The equilibrium constants of each reaction are:

\(SO_{2}_{(g)} + \frac{1}{2}O_{2}\) ⇔ \(SO_{3}_{(g)}\)

\(K_{1}=\frac{[SO_{3}]}{[SO_{2}][O_{2}]^{1/2}}\)

\(2SO_{3}_{(g)}\) ⇔ \(2SO_{2}_{(g)}+O_{2}_{(g)}\)

\(K_{2}=\frac{[SO_{2}]^{2}[O_{2}]}{[SO_{3}]^{2}}\)

Now, analysing each constant, it is easy to see that \(K_{1}\) is the inverse of \(K_{2}\).

If you doubled the first reaction, it will have the same coefficients of the second reaction. Since coefficients are "transformed" in power for the constant, the relationship is:

\(K_{2}=\frac{1}{K_{1}^{2}}\)

Explanation:

it is not a gas because the particles do not move freely it may be a liquid or a solid partly and mostly liquidized.

The claim that cold water boils faster than hot water is not true. The reason why this misconception may have emerged is likely due to a misunderstanding or misinterpretation of certain observations. However, there is no scientific evidence supporting this claim.

One possible reason for this misconception is the notion that hot water takes longer to reach its boiling point because it starts at a higher temperature. When comparing hot and cold water in terms of reaching the boiling point from room temperature, the cold water may appear to boil faster.

However, this is simply because the hot water has already gained a head start in terms of temperature. In reality, once both liquids reach their respective boiling points, the hot water will boil first.

Scientifically, the boiling point of water is determined by its temperature and pressure. Under normal atmospheric conditions, the boiling point of water is 100 degrees Celsius (212 degrees Fahrenheit). Heating water raises its temperature, and once it reaches 100 degrees Celsius, it transitions into the gaseous state. The initial temperature of the water does not affect the boiling point itself.

In conclusion, the claim that cold water boils faster than hot water is a misconception. It likely arose from a misinterpretation of observations, and there is no scientific evidence to support this claim. The boiling point of water is solely determined by its temperature and pressure, regardless of whether the water is initially hot or cold.

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because an equation to show the production of sodium chloride from calcium chloride should have been illustrated. However, if the balanced chemical equation showing sodium chloride (NaCl) been a product of a reaction involving calcium chloride (CaCl₂) as a reactant (shown below) is to be used, then we start by writing a complete balanced chemical equation

CaCl₂ + Na₂CO₃  ⇒   CaCO₃ + 2NaCl

From the equation above, it can be deduced that 1 mole of CaCl₂ is required to produce 2 moles of NaCl, thus how many moles of CaCl₂ will be required to produce 6.5 moles of NaCl.

1 mole of CaCl₂ = 2 moles of NaCl

? moles of CaCl₂ = 6.5 moles of NaCl

cross multiply

? moles of CaCl₂ = 6.5 × 1/2

? moles of CaCl₂ = 3.25 moles of CaCl₂

3.25 moles of CaCl₂ will be needed to produce 6.5 moles of NaCl

1) Diesel has a higher viscosity than petrol.

2) Petrol is more flammable than diesel.

3) The formula will be C₁₀H₂₂.

4) The equation is; 2C8H18+25O2→16CO2+18H2O.

Depending on the precise composition and temperature, the viscosity of gasoline and diesel can change. In general, diesel is more viscous than gasoline. Higher viscosity fluids are thicker and flow more slowly than lower viscosity fluids because viscosity relates to the resistance of a fluid to flow.

Diesel is less flammable than gasoline. The lowest temperature at which gasoline can evaporate and turn into an ignitable combination in air is known as its flash point, and it is lower for gasoline. Compared to diesel fuel, petrol vapors are much more flammable and can ignite at lower temperatures.

Answer:

what is the energy rate? or how much energy do you have.

Explanation:

The formula you provided calculates the percent change in pH based on the difference between the pH at 5 drops and the pH at 0 drops. Here's how you can use the formula:

1. Determine the pH at 5 drops and the pH at 0 drops.

Let's say the pH at 5 drops is 4 and the pH at 0 drops is 7.

2. Plug the values into the formula:

Percent Change of pH = 100% × (pH at 5 drops - pH at 0 drops) / pH at 0 drops

Percent Change of pH = 100% × (4 - 7) / 7

3. Calculate the numerator:

4 - 7 = -3

4. Calculate the denominator:

Percent Change of pH = 100% × (-3) / 7

5. Calculate the percent change:

Percent Change of pH = -300% / 7

Therefore, the percent change in pH from 0 drops to 5 drops is approximately -42.86%.

The volume of carbon dioxide produced is approximately (d) 11.9 liters.

To determine the amount of carbon dioxide (C\(O_2\)) produced when 37.8 grams of carbon disulfide (C\(S_2\)) reacts with excess oxygen gas (\(O_2\)), we need to use stoichiometry and the given balanced chemical equation:

C\(S_2\)(l) + 3\(O_2\)(g) → C\(O_2\)(g) + 2S\(O_2\)(g)

First, we calculate the number of moles of C\(S_2\) using its molar mass:

Molar mass of (C\(S_2\)) = 12.01 g/mol (C) + 32.07 g/mol (S) × 2 = 76.14 g/mol

Number of moles of (C\(S_2\)) = mass / molar mass = 37.8 g / 76.14 g/mol ≈ 0.496 mol

From the balanced equation, we can see that the stoichiometric ratio between (C\(S_2\)) and C\(O_2\) is 1:1. Therefore, the number of moles of C\(O_2\) produced will also be 0.496 mol.

Now we can use the ideal gas law to calculate the volume of C\(O_2\) at the given temperature and pressure. The ideal gas law equation is:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin.

Converting the temperature from Celsius to Kelvin:

T(K) = 28.85°C + 273.15 = 302 K

Using the ideal gas law:

V = nRT / P = (0.496 mol) × (0.0821 L·atm/mol·K) × (302 K) / (1.02 atm) ≈ 11.9 L

The correct answer is 11.9 liters.
