A flask contains the liquids trichloromethane (chloroform) and water. They are separated using a separating funnel, which conclusion can be made from this observation alone?
A. Trichloromethane and water have different relative molecular masses
B. Trichloromethane and water have different boiling points
C. Trichloromethane has a higher density than water
D. Trichloromethane is more volatile than water
E. Trichloromethane and water do not mix
Answers
Answer:
A
Explanation:
Based on the observation that trichloromethane (chloroform) and water can be separated using a separating funnel, the conclusion that can be made from this observation alone is:
E. Trichloromethane and water do not mix.
When two substances are immiscible, such as trichloromethane (chloroform) and water, it means that they do not dissolve or form a homogeneous mixture when combined. Instead, they form separate layers within the mixture.
The immiscibility between trichloromethane and water is primarily due to their different polarities and intermolecular forces. Trichloromethane is a nonpolar compound with relatively weak intermolecular forces, while water is a highly polar compound with strong intermolecular forces.
Water is a polar molecule due to its bent shape and the presence of electronegative oxygen atoms that create partial positive and negative charges. Trichloromethane, on the other hand, is a symmetrical molecule with four chlorine atoms surrounding a central carbon atom, resulting in a nonpolar distribution of charge.
The fact that these two substances can be separated using a separating funnel indicates that they are immiscible, meaning they do not mix or dissolve in each other to form a homogeneous solution. Trichloromethane and water have different polarities and intermolecular forces, causing them to form separate layers in the separating funnel.

Two students have been researching the atomic theory in preparation for their chemistry test. Melanie stated that Thomson's discovery revolutionized the understanding of an atom more than Rutherford. Josue disagreed with Melanie, he stated Rutherford's discovery revolutionized the understanding of an atom more than Thomson. Which student do you agree with?
Answers
Answer:
Josue
Explanation:
J.J Thompson proposed the plum pudding model of the atom. In his proposition, the atom is a sphere of positive charges into which negative charges were embedded. This model of the atom did not significantly contribute to our present day understanding of atomic structure.
On the other hand Ernest Rutherford laid out the foundation for a more accurate understanding of atomic structure in his nuclear model of the atom. According to Rutherford, the atom consists of a positively charged massive core called the nucleus around which electron move in orbits. His idea was akin to the solar system with the sun at it's core and planets moving around the sun in orbits.
This his idea of the nuclear theory was held as fundamentally correct by Neils Bohr's model of the atom. Hence, his nuclear theory of the atom was a significant milestone in our present day understanding of atomic structure.

You have decided to bake a cake. You mix all of your ingredients together to make a delicious chocolate cake. Then, you bake your cake at 350 degrees fahrenheit. You have to perform both a physical and a chemical change to bake a cake. What is the chemical change? Include at least 2 pieces of evidence or indicators to explain how you know it was a chemical change.
Answers
Answer:
A gas is evolved
The ingredients can not be recovered
Explanation:
A chemical change is one in which a new substance is formed and it is not easily reversible.
One major ingredient used in cake baking is the baking powder or baking soda.
Baking a cake can be viewed as a chemical change. This is because, when the baking powder or soda is added in the presence of yeast, carbon dioxide gas is evolved as tiny bubbles of gas which makes the cake light and fluffy. Heat is equally given off in the process. The baking powder and other cake ingredients can not be recovered, hence, we can conclusively assert that a chemical change has taken place.

1. a) 1.27 mol H₂SO₄
2. b) 19 g KCl
Explanation:
The grass method is an acronym for Given, Required, Application, Solution, Statement.
1. a) Given, 125g H₂SO₄; Required, find the moles H₂SO₄; Application, 125g x molar mass of H₂SO₄, Solution, [tex]125g H2SO4 * \frac{1molH2SO4}{98.08gH2SO4} = 1.274469molH2SO4[/tex] Statement, Round to the lowest number of significant figures to get 1.27 mol H₂SO₄;
2. b) I am only show the equation for this one, but it is basically the same as the previous one. The molar mass of KCl is 74.55 g/mol.
[tex]0.25molKCl*\frac{74.55gKCl}{1molKCl} = 18.6375 gKCl[/tex]
Round to the lowest number of significant figures which is two to get 19 g KCl.
For 3 the unit converter between moles and molecules is 6.022 x 10²³ molecules/mol.

23. A 54-gram sample of an unknown material has a volume equal to 20 cm'. Based on its density,
could the sample be aluminum? Explain.
Answers
Answer:
The density of aluminum is 2.7 g/cm³. Thus given sample is aluminum.
Explanation:
Given data:
Mass of sample = 54 g
Volume of sample = 20 cm³
Density of sample = ?
Is the sample is aluminum = ?
Solution:
We will calculate the density from given mass and volume.
d = m/v
d = density
m = mass
v = volume
d = 54 g/ 20cm³
d = 2.7 g/cm³
From literature it is known that the density of aluminum is 2.7 g/cm³. Thus given sample is aluminum.

Answer:
The answer is 5135 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density = 0.79 g/mL
1 L = 1000 mL
6.5 L = 6500 mL
We have
mass = 0.79 × 6500
We have the final answer as
