Answer:

Plants use carbon dioxide to make their food

Explanation:

The most important role of carbon dioxide in the ecosystem is that plants use the compound to make food.

Since plants are primary produces, the food is taken by other organisms in the ecosystem for their own nourishment.

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.

Explanation:

Students were asked to describe evidence of Plate Tectonic Theory.

descriptions listed above accurately describe evidence supporting Plate

Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."

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.

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.

Answer: 2) Chloroform & Caustic potash

Explanation:

The carbylamine reaction is a kind of chemical test which is done to detect primary amines in an unknown solution. It cannot detect secondary and tertiary amines.

The reaction involves the heating with up of the unknown solution with alcoholic potassium hydroxide or caustic potash and the chloroform.

In the presence of primary amine, the production of isocyanide results.

Answer:

This molecule is AgN3

Explanation:

Answer:

AgN3

Explanation:

Mass of nitrogen N is given as 24.36 g

Molar mass of nitrogen N= 14 g/mol.

amount of substance in mol of N = mass/molar mass

=24.36 g/ 14 g/mol.

=1.74 mol.

Given mass of silver= 62,64 g.

Molar mass of silver Ag=107.87 g/mol

Number of mols=62.64 g ÷ 107.87 g/mol.

=0.58 mol.

Ratio of number of mol of N and number of mols of Ag = 1.74 mol / 0.58 mol

=3:1

Hence, empirical formula is AgN₃.

Answer: it’s the first one ☝️

Mass NEVER changes

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

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.

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.

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 ≈

Explanation:

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.

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,

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.
