P_4O_8

How?

Let's learn how to create name of compound from its name.

Look below for root words

  • 2-di
  • 3-tri
  • 4-tetra
  • 5-pent
  • 6-hex
  • 7-hept
  • 8-oct
  • 9-non
  • 10-dec

Hence formula of the compound is P4O8

Temperature is the______
Natasha2012 [34]

<u>Answer:</u> Temperature is the independent variable and amount of sugar in the solution is the dependent variable.

<u>Explanation:</u>

Dependent variable is defined as the variable whose value changes with respect to any other variable.

Independent variable is defined as the variable which remain as such and has no effect on the change of another variable. <u>For Example:</u> Time

Solubility is a property of substance to interact with the solvent particles. Thir property is dependent on temperature.

As, the temperature of the system increases, the solubility of the substance will increase and vice-versa.

Hence, temperature is the independent variable and amount of sugar in the solution is the dependent variable.

A compound containing sodium, chlorine, and oxygen is 25.42% sodium by mass. A 3.25 g sample gives 4.33×1022 atoms of oxygen. Wh
Tcecarenko [31]
step  one 
calculate  the  %  of  oxygen
from  avogadro  constant
1moles =  6.02  x  10  ^23  atoms
what  about    4.33  x10^22  atoms
= ( 4.33  x  10^ 22 x 1 mole )  /  6.02  10^23=   0.0719 moles
mass=  0.0719  x16=  1.1504   g
% composition   is therefore= ( 1.1504/3.25)  x100 = 35.40%
 step  two
calculate the  %  composition  of  chrorine
100-  (25.42  +  35.40)=39.18%

step  3
calculate the  moles   of  each  element
that   is  
Na  =  25.42  /23=1.1052  moles
Cl=  39.18  /35.5=1.1037moles
O=  35.40/16=  2.2125   moles
step  4
find  the  mole  ratio  by  dividing  each  mole  by  1.1037  moles
that  is
Na  =  1.1052/1.1037=1.001
Cl= 1.1037/1.1037=  1
0=2.2125 = 2
therefore  the  empirical  formula= NaClO2

Assume you find four bottles in an empty laboratory, each containing a liquid. The labels that were on these bottles have fallen
fenix001 [56]

Answer:

No, I can not identify the contents of each bottle using solubility and polarity (with H2O) information

Explanation:

While it is true that polar substances dissolve in water and nonpolar substances do not dissolve in water, the task here is to specifically identify the contents of each of the bottles.

Solubility in water can not tell us exactly what liquid is which substance. For instance, trans-1,2-dichloroethylene, cis-1,2-dichloroethylene and cyclooctane are all insoluble in water. The fact that they do not dissolve in water does not tell us which liquid is which compound.

Even though acetic acid is miscible with water, it is not a conclusive prove that the liquid is acetic acid since other polar organic compounds are also miscible in water.

It is only by determining the boiling point of each substance that I can conclusively identify the contents of each bottle since boiling point is an intrinsic property of substances.
