Please answer the following essay question with 5-7 sentences.
How is a chemical change different from a physical change?

Answers

Answer 1
Chemical change is different from physical change because physical change is the appearance or form changes. but the matter in the substance does not change. but in chemical change the kind of matter changes and at least one new substance with new properties is formed. *you can add more punctuations to make it 5-7 if you would like:)*
Answer 2
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.

If two oceanic plates move towards each other at a convergent boundary, then_____ may occur.

earthquakes

ocean formation
mountains
volcanoes
island chains
seafloor spreading

pick two events

Answers

earthquake and mountains

Answer:

I think the answer is Volcanoes.

Explanation:

If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.

When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.

Precipitate has different meanings so I didn't really know about which one, but tell me if I'm wrong :)

Answer:

Reactant: a substance that takes part in and undergoes change during a reaction.

Product: are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state.

How is energy involved in physical change?

Answers

the amount of energy that is used changes the amount of physical change that is shown

During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants.

Explain the correlation between chemical properties and chemical changes. (plz i not sure on the answer so it would mean a lot if you could help me.)

Answers

Answer:

Explanation:

A chemical property describes the ability of a substance to undergo a specific chemical change.

A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

Differences

Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.

Physical properties are properties that can be observed without bringing a chemical change.

Another one

chemical properties; can be used to predict how substances react.

chemical changes; It is mostly used in identifying or describing the substance.

A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.[1] Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected greatly for its chemical properties to be investigated. When a substance goes under a chemical reaction, the properties will change drastically, resulting in chemical change.


Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

Answers

Answer: ... being that the food she eats food that contains a lot of protein and also starch, so systems are both good for you and work together. Chemical energy is stored in the bonds of sugars. When a sugar molecule is broken down, a usable form of energy is released for the cell's life functions. Cells can release energy in two basic processes: cellular respiration and fermentation. ... In cells use oxygen to release energy stored in sugars such as glucose.

Explanation:

Answer:

What does she need from the food she ate and the air she breathes so that she can go on her run?

A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).

B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.

How do Rosa's body systems work together to get the molecules she needs into her cells?

Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).

2. 1. Your best friend has missed a lot of school recently. Your teacher has allowed you to create a study guide and will let your friend use it on the test.

The guide should include:
• descriptions of amplitude, wavelength, frequency, and wave speed.
• Give examples of the wave relationship between amplitude and wavelength (if there is no relationship, explain how you know)
• Give examples of the wave relationship between wavelength and frequency (if there is no relationship, explain how you know)Text to speech

Answers

Answer:

Hi (best friend)! Here is what you missed!

Five wave parameters are defined and measured: the time, the frequency, the amplitude, the wavelength, and the speed. The wave length is the time it takes to pass a full phase. The frequency is just the opposite; it's the number of wave cycles that have been completed in a second.

Lets give a wave of water as an example. Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity vw. Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.
