Relate the effect of temperature and pressure on

Chemistry
1 answer:
Anna007 [38]4 years ago
5 0

Answer:

According to the Kinetic-molecular theory, <u>increase in temperature</u> causes the <u>gas molecules' average speed and kinetic energy to increase</u>.if the <u>volume of the container is held constant</u>, <u>collision of gas molecules</u> will be <u>frequent</u> and with more force on the walls of the container,making the <u>pressure to increase.</u>

Explanation:

Remember that a gas pressure is affected by the rapidness of moving gas molecules which is directly proportion to number of molecules hitting a unit area of the container in a unit time.Kinetic-molecular theory can be explained from Boyle's law where a decreased volume of a container compresses the gas in the container due to reduced area,making gas molecules to collide with high frequency rising the pressure exerted by the gas.

In the covalent compound CH3, the Greek prefix used to represent the anion is Answer here​
Contact [7]

Answer:

Tri.

Explanation:

''Tri'' is the Greek prefix used to represent the CH3 because there are three hydrogen atoms to form the covalent compound so in Greek method ''Tri'' is used for three. In Greek system, there are certain names for prefixes such as ''di'' is used for two, ''tri'' is used for three, ''tetra'' is used for four etc. This method only provides information about the number of atoms that form the covalent compound.

write a skeletal equation for the following reaction: An aqueous solution of barium nitrate and an aqueous solution of sodium su
belka [17]

Answer: skeletal equation : Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)

The products are sodium nitrate and barium sulphate.

balanced equation :  Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The skeletal equation is:

Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)

The balanced chemical equation is:

Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)

What is arranged to form a material with a crystal structure
mafiozo [28]

Answer:

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. The scientific study of crystals and crystal formation is known as crystallography.
