Explain how the crystals of an igneous rock are used to help classify it?

A) What characteristics of physical properties distinguish metals from nonmetals?

salantis [7]

Answer:

The answer to your question is:

Explanation:

a)

Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.

Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.

b)

Metals are located in the left side of the periodic table

Nonmetals are located in the right side of the periodic table.

c)

Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.

Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.

if the relationship between tempurature and volume of a gas at a constant pressure is linear, explain why the volume of a gas do

Lilit [14]

The gas has already created enough pressure to become a gas, which is the most expandable it could turn in to. Thats what i think, hope it helps.

Problem page in each of the molecules drawn below one chemical bond is colored red. decide whether this bond is likely to be pol

Slav-nsk [51]

The question is incomplete, here is the complete question:

Problem page in each of the molecules drawn below one chemical bond is colored red. Decide whether this bond is likely to be polar or not. if the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge.

The image is attached below.

Answer:

For carbon dioxide molecule: The bond is considered as polar and the elecvtronegative atom is oxygen.

For water molecule: The bond is considered as polar and the elecvtronegative atom is oxygen.

Explanation:

There are two types of covalent bonds:

Polar covalent bond: This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: $CO_2,NO_2$ etc..
Non-polar covalent bond: This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc..
