<u>Answer:</u> The empirical formula for the given compound is 
<u>Explanation:</u>
We are given:
Mass of pure compound containing copper and sulfur = 4.963 g
Mass of S = 1.000 g
Mass of Cu = (4.963 - 1.000) g = 3.963 g
To formulate the empirical formula, we need to follow some steps:
- <u>Step 1:</u> Converting the given masses into moles.
Moles of Copper =
Moles of Sulfur = 
- <u>Step 2:</u> Calculating the mole ratio of the given elements.
For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.0312 moles.
For Copper = 
For Sulfur = 
<u>Step 3:</u> Taking the mole ratio as their subscripts.
The ratio of Cu : S = 2 : 1
Hence, the empirical formula for the given compound is 
Answer: None of the above statements is false.
Explanation:
In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.
In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.
In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.
Thus, we can conclude that none of the given statements are false.
Answer:
Because the rock is irregularly shaped, you used the displacement method to measure its volume. You used <u>calculations</u> to indirectly find the <u>density</u> of the objects.
