I is rusting car, II is water boiling, III is cooking eggs and IV is melting ice cream

A. I

B. I and III

C. II and IIII

D. I, II, and III

Answers

Answer: B

Explanation:

I. Rusting is a chemical reaction which is oxidation of iron.

II. Boiling water is a physical change. There is no chemical change between H2O molecules. It only shifts to the gas state from the liquid state.

III. When egg is cooked proteins are denaturated so it changes interactions between molecules.

IV. Melting is also just a phase change like boiling.

Which statement correctly describes the relationship between molecular structure, the strength of electrostatic forces between

The boiling point of a substance affects its molecular structure, which can affect the the strength of

Molecular structure affects the strength of electrostatic forces, which can affect the boiling point of a
substance
Stronger electrostatic forces cause a stronger molecular structure and lower boiling points

Answers

Molecular structure affects the strength of electrostatic forces, which can affect the boiling point of a substance is the statement that correctly describes the relationship between these terms.

The molecular structure is the way in which the atoms that are in a molecule are arranged in space, this is defined by a series of forces that hold the atoms together in a specific arrangement.

The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure that surrounds the liquid, when this happens, the liquid transforms into gas.

For a compound to vaporize, the forces that hold the molecules together must be broken, this means that the boiling point of a compound depends on the attraction between the molecules, that is, on the forces that determine the molecular structure.

If the molecules are held together by strong electrostatic forces, it will take a lot of energy to push the molecules away from each other and the compound will have a very high boiling point.

Therefore, we can conclude that the boiling point depends on the molecular mass of the substance and the type of electrostatic forces present, that is, the bonds that the atoms establish with each other to form the molecule (molecular structure).

A. has set electron orbits.
B. has positive and negative particles in the nucleus.
C. can be represented in one dimension.
D. answers many questions about atoms.

Answers

Answer:

its D. answers many questions about atoms.

The modern-day quantum model of the atom is better than John Dalton’s model because it "  answers many questions about atoms."

What is quantum model ?

This concept also referred to as the quantum mechanical and wave mechanical model, would be the cornerstone of contemporary atomic theory. The fact that an electron inside an atom may only exist in a limited range of states or energy is analogous to a standing wave.

What is John Dalton’s model ?

Dalton proposed that the concept of atoms will be used to explain the laws of conservation of mass as well as definite proportions. Imagining atoms as "solid, massy, hard, impenetrable, moving objects," he claimed that almost all matter would be composed of these tiny, indivisible particles.

Dalton also stated that almost no atom might be formed, converted into another, as well as destroyed. The complex shapes of orbitals also known as electron clouds used in the quantum mechanical atomic model are areas of space where an electron is likely to be present. So rather than being based on certainty, this model would be probability based.

Therefore, the correct answer will be option (D)

A student mixes 20.0gof white KCl crystals with distilled water in a beaker. After the mixture was stirred, no crystals are visible and the solution is clear. After several days, all of the water evaporates and white crystals are found in the beaker. Which of following pieces of experimental evidence would best help the student to confirm that a new compound had not been made and that only a physical change occurred?
a- The solution does not change color after stirring.
b- The KCl crystals are no longer visible after mixing with water.
c- There is a temperature change in the solution during the dissolving process.
d- After the water has evaporated, the white crystals in the beaker have a mass of 20.0g

Answers

Answer:d

Explanation: over time water evaporates which leaves you with the white crystals mass

A student in a beaker mixes 20.0 g of white KCl crystals with distilled water; no crystals are visible, and the solution is clear, indicating that the physical change has occurred, which is that after the water has evaporated, the white crystals in the beaker have a mass of 20.0 g; that is option d.

What is the significance of the physical change?

The physical change includes the change in the shape and size of the substances but not the chemical change, as in the case of here the crystal, which is left behind after the evaporation of the solution without any change in the chemical composition.

Hence, a student in a beaker mixes 20.0 g of white KCl crystals with distilled water; no crystals are visible, and the solution is clear, indicating that the physical change has occurred, which is that after the water has evaporated, the white crystals in the beaker have a mass of 20.0 g; that is option d.

As the ionic compound increases in
complexity, the melting point
A. increases
B. decreases
C. stays the same

Answers

Given what we know, we can confirm that as an ionic compound grows more complex, its melting point will increase.

What is an Ionic compound?An ionic compound is one in which atoms of elements share electrons between them to form compounds.These shared electrons generate powerful electrostatic forces that we refer to as ionic bonds. Electrostatic forces cause an increase in the melting point of a compound. As a compound grows more complex and adds more elements to its composition, it will gain new electrostatic forces, and thus increase its melting point.

Therefore, as an ionic compound grows more complex, its melting point will increase due to the increasing number of strong electrostatic forces present in the compound.

do Plants and animals create energy the same way?

Answers

Answer:

Yes

Step By Step Explanation:

Plants extract energy from food molecules the same way animals do — by cellular respiration.

Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called "photosynthesis". ... Plants get their energy in form of starch whereas animals get it in form of glycogen. Animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.

Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP.

Hopes This Helps

Plants extract energy from food molecules the same way animals do — by cellular respiration. When plants do cellular respiration, they produce carbon dioxide and use oxygen just like animals do.
