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.

Answer:
Cr₂S₃
Explanation:
From the question given above, the following data were obtained:
Mass of chromium (Cr) = 0.67 g
Mass of chromium sulfide = 1.2888 g
Empirical formula =?
Next, we shall determine the mass of sulphur (S) in the compound. This can be obtained as follow:
Mass of chromium (Cr) = 0.67 g
Mass of chromium sulfide = 1.2888 g
Mass of sulphur (S) =?
Mass of S = (Mass of chromium sulfide) – (Mass of Cr)
Mass of S = 1.2888 – 0.67
Mass of S = 0.6188 g
Finally, we shall determine the empirical formula of the compound. This can be obtained as follow:
Mass of Cr = 0.67 g
Mass of S = 0.6188 g
Divide by their molar mass
Cr = 0.67 / 52 = 0.013
S = 0.6188 / 32 = 0.019
Divide by the smallest
Cr = 0.013 / 0.013 = 1
S = 0.019 / 0.013 = 1.46
Multiply by 2 to express in whole number
Cr = 1 × 2 = 2
S = 1.46 × 2 = 3
Therefore, the empirical formula of the compound is Cr₂S₃
Answer:

Molecular Weight/ Molar Mass: 74.44 g/mol
Density: 1.11 g/cm³
Explanation:
Answer:
it's a covalent compound
Explanation:
Two non metals are bonded to together
The attractive force that occurs between the sun and the earth is called:
Gravity
This force works to keep everything on the planet grounded.
