Answer:

Characteristics of a compound

The properties of a compound are different from the properties of its constituents. Formation of a compound is generally accompanied by evolution of energy in the form of heat or light. A compound has a fixed melting point and boiling point. A compound is always homogeneous in nature.

Bogdan [553]

Answer: <em>Newton's first law</em>

Explanation: <em>The idea that objects only change their velocity due to a force is encapsulated in Newton's first law. Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.</em>

Which matter has more attraction between the particles​
julia-pushkina [17]

There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases. There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together.

Is the temperature at which a substance melts the same as the temperature changes from a liquid to a solid
sasho [114]

Answer:

No.

Explanation:

If the temperature changes a substance from it's original form, going from solid to liquid, then the temperature required to change it from a liquid to a solid are the opposite. For example, Ice is Water (H2O) in it's solid form. In order to freeze water into ice, the temperature must be very low. In order to melt the ice back into water, the temperature must be higher than the freezing point, but not too high or it will boil, making it a gaseous substance instead.

Susan has a beaker with one mole of water and another beaker filled with one mole of hydrogen chloride. Compare the number of mo
lisabon 2012 [21]

Answer:

Ratio is 1:1 ; they have same number of molecules.

Explanation:

One mole of any compound have same number of molecules, irrespective of their chemistry and composition, i.e. 6.022x10^23 . This number is known as Avogadro's Number.

So the beaker with one mole of water contains = 6.022x10^23 molecules ;

and beaker with one mole of Hydrogen chloride = 6.022x10^23 molecules.

The comparative ratio is 1:1.
