The planet that would have a diameter of approximately 12 cm is Saturn.

<h3>What is a scale model?</h3>

A scale model is a model which is used to represent another object using a given scale.

Scale models can be used to make small object bigger or larger objects smaller.

Considering the scale model of the planets where  1 centimeter (cm) is equal to 10,000 kilometers (km);

1 centimeter = 10,000 kilometers

12 centimeter = 1.2 × 10⁵ kilometers

The planet with a diameter of approximately 1.2 × 10⁵ kilometers is Saturn.

In conclusion, scale models are used to model objects.

If the pressure in a gas cylinder is heated to 354.2 K with the pressure of 2.64 atm that was the initial temperature if the ini
MrMuchimi

Answer:

Initial temperature of the gas cylinder was 167.7K

Explanation:

Based on Gay-Lussac's law, the pressure of a gas under constant volume is directly proportional to its absolute temperature. The equation is:

P1*T2 = P2*T1

<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>

<em />

Replacing:

P1 = 1.25atm

T2 = 354.2K

P2 = 2.64atm

T1 = ?

1.25atm*354.2K = 2.64atm*T1

167.7K = T1

A Wisconsin farmer taps a maple tree and collects 200 liters of sap. He determines the sucrose (C12H2011) concentration to be 0.
Minchanka [31]

Answer:

6.0 L

Explanation:

Use the dilution equation M1V1 = M2V2

M1 = 0.075 M

V1 = 200 L

M2 = 2.5 M

V2 = ?

Solve for V2 --> V2 = M1V1/M2

V2 = (0.075 M)(200 L) / (2.5 M) = 6.0 L

If 1.00 mol of argon is placed in a 0.500-L container at 29.0 ∘C , what is the difference between the ideal pressure (as predict
Mashcka [7]

Answer:

Ideal ,P=49.52 atm

Real ,P=47.62 atm

Explanation:

Given that

n= 1 mol

V= 0.5 L

T= 29  ∘C = 29 +273 K

T= 302 K

For ideal gas

P V = n R T

P x 0.5 = 1 x 0.0821  x 302

P=49.52 atm

For real gas

\left ( P+\dfrac{an^2}{v^2} \right )\left ( v-nb \right )=nRT

Now by putting the values

\left ( P+\dfrac{1.345\times 1^2}{0.5^2} \right )\left ( 0.5-1\times 0.03219 \right )=1\times 0.0821\times 302

\left ( P+\dfrac{1.345}{0.5^2} \right )=53

P=47.62 atm
