The Balanced equation will be :

$\mathrm{ \boxed2Fe + \boxed3Cl_2 \rightarrow \boxed2FeCl_3}$

The Coefficients are :

$Fe - 2$

$Cl_2 - 3$

$FeCl_3 - 2$

Which mixture can be separated based on differences in the particle size of the components?

Rina8888 [55]

Answer: Mixtures you can separate are like cereal and milk. Hope that helps

Explanation: Filteration is required to separate a mixture.

So heterogeneous mixures (that contain substances with different particle sizes) can be separated with a filter.

Homogeneous mixtures are uniform in composition so they will not be able to be separated.

A 2.912 g sample of a compounds containing only C, H, and O was completely oxidized in a reaction that yielded 3.123 g of water

Taya2010 [7]

Answer:

Explanation:

18 gram of water contains 2 g of hydrogen

3.123 gram of water will contain 2 x 3.123 / 18 = .347 g of hydrogen .

44 gram of carbon dioxide contains 12 g of carbon

7.691 gram of carbon dioxide will contain 12 x 7.691 / 44 = 2.1 g of carbon .

So the sample will contain 2.912 - ( .347 + 2.1 ) g of oxygen .

= .465 g of oxygen .

moles of Carbon = 2.1 / 12 = .175

moles of hydrogen = .347 / 1 = .347

moles of oxygen = .465 / 16 = .029

Ratio of moles of carbon , oxygen and hydrogen ( C,O,H )

= 0.175 : 0.029 : 0.347

= .175/ .029 : 1 : .347 / .029

= 6 : 1 : 12

So empirical formula = C₆H₁₂O

Let the molecular formula be $(C_6H_{12}O)_n$

molecular weight = n ( 6 x 12 + 12x 1 + 16)

= 100 n

Given 100 n = 100.1

n = 1

Molecular formula = C₆H₁₂O.
