Students were asked to describe evidence of Plate Tectonic Theory. Their answers are listed
below.
Student 1: The shape of the continents suggests that they were once connected together.
Student 2: Similar fossils and rock formations have been found across different continents
providing evidence that they were once connected.
Student 3: Glacial evidence indicates that different
continents were once connected near the
South Pole.
Student 4: Magnetic rocks indicate that the sea floor has been growing and spreading over
time.
Which student(s) descriptions listed above accurately describe evidence supporting Plate
Tectonic Theory?
Answer:
One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.

Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."
What is plate Tectonic Theory?
The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere was made up of many major tectonic plates that have already been gently migrating since around 3.4 billion years ago.
What is the South Pole?The south pole would be one of two locations on Earth's surface at which the planet's axis of rotation crosses it. It is often referred to as one of the Geographic south pole, Terrestrial South Pole, and 90th Parallel South.
The fossil record is such sort of evidence that has been used to support the Claim of Continental Drift. On the coastlines of many continents, fossils of specific kinds of plants, as well as animals have been discovered in rocks that are comparable in age, indicating that the continents had been connected.

2b. 12 grams of C8H18 react with oxygen to produce carbon dioxide and water. How many grams of CO2 are produced?
12.4
13.5
11.6
37.1
Other:
Answer:
37.1g are produced
Explanation:
The combustion of C₈H₁₈ is:
C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O
Where 1 mole of C₈H₁₈ produce 8 moles of CO₂
To find the mass of CO₂ that is produced we need to convert the mass of C₈H₁₈ with molar mass. Then, with the chemical equation, we can find the moles of CO₂ and its mass, as follows:
Moles C₈H₁₈ -Molar mass: 114.2g/mol-
12g C₈H₁₈ * (1mol / 114.2g) = 0.105 moles of C₈H₁₈
Moles CO₂:
As 1 mole of C₈H₁₈ produce 8 moles of CO₂, 0.105 moles of C₈H₁₈ produce:
0.105 moles of C₈H₁₈ * (8moles CO₂ / 1mole C₈H₁₈) = 0.84 moles of CO₂
Mass CO₂ -Molar mass: 44.01g/mol-:
0.84 moles of CO₂ * (44.01g / mol) = 37.0g of CO₂ ≈

If you start with 3 moles of sodium and 3 moles of chlorine to produce sodium chloride, what is the limiting reagent?(You will need to balance
the equation first.)
Na + Cl2 -> NaCl A. They are equal B. Na C. Cl2 D. NaCl
Answer:
B. Na
Explanation:
Once balanced you get 2Na + Cl₂ ⇒ 2NaCl. Sodium is the limiting reagent because it would produce the smallest amount of the product (NaCl)–while chlorine is the excess reagent. Based off of the Na in the balanced equation, it would produce 3 moles of NaCl, and for Cl₂ it would produce an excess of 6 moles of NaCl. [It'd be wise to utilize stoichiometric factors to get a good grasp of this]

3. Calculate the number of moles and mass in
gram_of_1 x 10^20mdecules of Nz gas
.
Answer:
0.17×10⁻³ mol
Mass = 0.00476 g
Explanation:
Given data:
Number of molecules of N₂ = 1 ×10²⁰ molecules
Number of moles of N₂ = ?
Mass in gram of N₂ = ?
Solution:
1 mole of any substance contain 6.022×10²³ molecules
1 ×10²⁰ molecules× 1 mol /6.022×10²³ molecules
0.17×10⁻³ mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.17×10⁻³ mol × 28 g/mol
Mass = 4.76×10⁻³ g
Mass = 0.00476 g

Methane(CH4) is a gas at room temperature, Methanol (CH3OH) is a liquid. Explain why using types of intermolecular forces present.
Explanation:
Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.
Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.
What are intermolecular forces?An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.
Intermolecular forces are classified into five types namely,
Ion-dipole forces.Ion-induced dipole forces.Dipole-dipole forces.Dipole-induced dipole forces.Induced dipole forces.Between ions and polar dipole molecules, ion-dipole forces exist.
Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.
This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.
Thus, this is the reason of using types of intermolecular forces present.

In which material would the particles be closest together?
O Syrup
O Brick
O Air
O Water
Answer:

Explanation:
The distance between particles is best determined by density. So, to find which material has the most compacted particles, we need to find which material has the highest density. Solids will always have the highest densities, so Brick would have the particles that are closest together.

Which process is caused by natural selection
Answer:
Four general conditions necessary for natural selection to occur are: More organisms are born than can survive. Organisms vary in their characteristics, even within a species. Variation is inherited.
Answer:
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Explanation:
Suppose you pour a glass of ice water and set it on the kitchen table. After a few minutes, the outside of the glass will be covered with drops of water. Why did this happen?
For condensation to take place there should be noticeable difference between the temperature of the system and the atmosphere. Thus condensation is the reason for clinging of water particles to the side of the glass.
What is condensation?Condensation is a process in which the vapor state converts to liquid state. Condensation is the reverse process of evaporation. Condensation occur at dew point. Dew point is the temperature at which condensation starts.
When the hot air particles collides with the surface of the glass having ice water, then the hot particles that had so much energy or kinetic energy suddenly reduces its energy and converts to water due to the change in temperature and pressure .
Thus condensation is the reason for clinging of water particles to the side of the glass having ice water.
