Extrusive rock because it takes longer to cool, making the crystal size larger
Answer:
neutral atoms when an atom is charge less
Explanation:
Answer:
The molar concentration would have to be 0,81 M.
Explanation:
The osmotic pressure equation is:
where:
: osmotic pressure [atm]
M: molar concentration [M]
R: gas constant 0,08205 [atm.L/mol.°K]
T: absolute temperature [°K]
To solve the problem, we just clear M from the osmotic pressure equation and then replace our data using the appropiate units. Clearing the variable M we have:
We have to use temperature as absolute temperature (in kelvins), T=29+273=302 °K. Now we can replace our values in the equation:
As we can see, all units will be simplified and we'll have the molar concentration in mol/L.

Menirals have definite chemical composition
- Minerals have crystalline structure
<u>Explanation:</u>
Minerals should be found in nature. Elements made laboratories are not actual minerals like masquerading as rubies or sapphires. All naturally available crystals are not minerals like opal and amber.
Minerals are not under any class of organic compounds. Almost all known minerals come from inorganic processes. Some minerals originate from organic processes like pearls.
Minerals exist only as solids. Solids have a defined volume and shape, and they cannot be compressed any further. Minerals are rigid.
- Definite chemical composition
Each mineral has a unique combination of atoms that cannot be found in other minerals. The strength of mineral can be defined by the type of bond a mineral has. Some minerals, like gold and diamond, have only one element in it.
Minerals form crystals that have repeated arrangements of ions. Minerals have different shapes depending on the size of the ion. Crystals usually take six types of shapes.
