hat is the percentage of water in the following compound? Answer using three significant figures. Sodium carbonate decahydrate,

BigorU [14]

You need to find the whole molar mass of the compound using the periodic table to add the values.

Na2CO3= (2 x 23.0) + 12.0 + (3 x 16.0)= 106 g/mol
H2O= 10 x [ (2 x 1.01 ) + (16.0) ]= 180.2 g/mol

the total molar mass is 106 + 180.2 = 286.2 g/mol

the percentage of water you can find by doing "parts over the whole"

H2O%= 180.2 / 286.2 X 100= 63.0%

Since there are many organic compounds,how can you distinguish one organic compound from another

iogann1982 [59]

What are organic and inorganic compounds? Organic chemistry is the study of the carbon compounding molecules. Inorganic chemistry, by contrast, is the study of all compounds that do NOT contain carbon compounds.

Identify the ion ratios needed to form neutral compounds from the ions below. The metal ion (cation) is listed first, and the no

Natasha2012 [34]

To figure out the ratios of these compounds, it is important to remember that the charge of these compounds must be <em>neutral</em>.

So in order to make them neutral, you must have specific ratios:

$Na^{+}: Br^{-} =1:1$ ; This is true because they both have a charge of magnitude of 1.

$Al^{3+}: Cl^{-}=1:3$ ; We need 3 chlorine atoms because we need to balance out the charge from the 3+ charge of aluminum - therefore since chlorine has a 1- charge, we need 3 atoms.

$Mg^{2+}: O^{2-}=1:1$ ; The charges of the magnesium (2+) are balanced with the oxygen charge (2-).

$Al^{3+}: O^{2-}=2:3$ ; This is correct because if charges are like this, you must find the least common factor in order to know the ratio. The LCF is 6, therefore, for the atom with a 3+ charge, you need 2 of them, and for the atom with a 2- charge, you need 3 of them. This keeps the charge neutral.

Describe a method to separate the substances in a solution.

zhenek [66]

Answer:

By using different techniques.

Explanation:

For example: Chromatography involves solvent separation on a solid medium. Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes.
