What is the difference between a compound and a mixture?



Group of answer choices

A compound is just a mixture of elements.

A mixture can be physically separated into its components; a compound cannot be physically separated into its components.

The components of a mixture do not have the same properties individually as they do when mixed.

A compound can be physically separated into its components; a mixture cannot be physically separated into its components.

Answers

Answer:

Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.

Answer:

The answer is a mixture can be physically separated into its components; a compound cannot be physically separated into its components.

which option is an example of a physical change??

A breaking chemical bonds

B forming chemical bonds

C nuclear decay

D melting a substance

which option is an example of a chemical change
A ironing a shirt

B melting cheese

C grinding powder

D fireworks exploding

Answers

Answer:

D

Explanation:

Melting of ice is a physical change as there no new compound is forming only state is changing So Option D is correct option. For second question Option D is correct option as combustion reaction is taking place.

What is chemical change?

Chemical change is a reaction in which breaking and forming of new bonds take place. One molecule completely converted to totally different molecule. The number of atoms remains same

One famous example of chemical change is the rusting of iron. The color, odor and arrangements of atoms in products are very much different from reactant. Chemical change are mostly irreversible in nature.  Physical change is just opposite of chemical change. Phase change is an example of physical change.

Thus option D  is correct option in both cases.

2. If a person in a wheelchair wanted to get to the second story of a two-story building, would it be easier to
take a short, steep ramp or a long, shallow ramp? Explain.

Answers

Answer:

The short steep ramp would be much harder because you will have to work more against gravity.

Explanation:

The long shallow ramp would be easier to take than the short, steep ramp because the person would have to use more force on the short, steep ramp to push the wheelchair against the force of gravity.

What is an inclined plane?

An inclined plane or a ramp can be defined as a flat supporting surface tilted at an angle, with one end higher than the other, utilized as an aid for raising or lowering a load.

The inclined plane can be defined as one of the six classical simple machines developed by Renaissance scientists. Inclined planes can be utilized to move heavy loads over vertical obstacles.

Moving a body up an inclined plane needs less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage, the factor by which the force is decreased, is equal to the ratio of the sloped surface's length to the height it spans.

The inclined plane provides the same amount of work to be done with a smaller force exerted over a greater distance. The angle of friction or the angle of repose can be defined as the maximum angle at which a load can rest motionless on an inclined plane because of the friction without sliding down.
