Answer:

Compound is made of two or more than two elements in a fix ratio by mass. Compounds have different properties from the parent elements.

Explanation:

The chemical and physical properties of compound are different from the parent materials because it is produced from the chemical combination of elements. In chemical combination, bonds are formed and new substance is produced which is quite different from the parent substances. For example, CO2 is produced when carbon and oxygen react with each other. The properties of CO2 are different from carbon and oxygen.

Answer: A compound

Explanation: A compound is a substance which contains two or elements chemically combined together.

The properties of a compound are different from the properties of the individual elements. For example, water H2O which is made up of hydrogen and oxygen atoms has properties different from the individual properties of hydrogen and oxygen.

Also, water is a compound made up of hydrogen and oxygen atoms which are combined in the ratio is 2 hydrogen atoms to 1 oxygen atom.

Imagine that Ana has a block made of pure gold. If she cuts this block into two equal pieces, pick the statement that best descr
dimaraw [331]

Answer : The correct statement is:

The density of each piece is the same as that of the original block.

Explanation :

Intensive property : It is defined as a property of substance which does not change as the amount of substance changes.

Examples: Temperature, refractive index, density, hardness, etc.

According to question, if Ana has a block made of pure gold and she cuts this block into two equal pieces then the density of each piece is the same as that of the original block because density is an intensive property that does not changes until and unless material is changed.

That means density remains same as that of the original piece.

Hence, the correct statement is the density of each piece is the same as that of the original block.

two samples of water, 10 grams and 50 grams are in sperate cups which of the following properties is different for the two boili
Trava [24]

Answer:

volume

Explanation:

The volume of the two samples of water will be different because volume is the amount of space occupied by a body. It is dependent on the amount of materials it contains.

  • The 50g sample will have a higher volume compared to the 10g sample.
  • The boiling point and density are intensive properties and do not depend on the amount of matter present.
  • Since both samples are from the same source, they will have the same color.

What is the relationship between the Kuiper Belt and the status of Pluto today?
Xelga [282]

Pluto is a dwarf planet, but one of the largest known members, in the Kuiper belt.

The Kuiper Belt extends between 30 AU and 55 AU from the Sun

(1 AU = 1.5 × 10^8 km = distance from Earth to Sun).

Pluto's orbit is highly elliptical. It ranges from 30 AU to 50 AU. When Pluto is closest to the Sun, it is inside the orbit of Neptune (30 AU).

Astronomers class Pluto as a <em>resonant Kuiper belt object</em> (KBO). Because it gets so close to Neptune, its orbit is in <em>resonance</em> with that of Neptune. Pluto makes two orbits for every three of Neptune.
