Sodium hydroxide, NaOH; sodium phosphate, Na3PO4; and sodium nitrate, NaNO3, are all common chemicals used in cleanser formulati
Sholpan [36]
Start by writing out molar mass of each component: 

1) NaOH= 22.99+16+1.01 --> 40 

2) Na₃PO₄= (22.99)3 + 94.97 + 64 --> 227.94

3) NaNO₃= 22.99 + 14 + 48 --> 84.99 

Now compare the mass of sodium with the rest of the substances: 

1) (22.99/40)100%= 57.475%

2) (68.97/227.94)/100%= 30.25% 

3) (22.99/84.99)/100%= 27.05%

As seen, the ordered list is: Sodium hydroxide, sodium phosphate and sodium nitrate. 

Hope I helped :)

Describe the relationship between volume and temperature of an ideal gas, and explain it in terms of the kinetic molecular theor
melisa1 [442]

As temperature increases, the particles will gain kinetic energy causing it to move more rapidly and randomly. However, this causes the gas to expand as the particles will have more energy to roam freely. Hence as temperature increases, Volume increases.

This is based on Charles' Law stating that the volume of a gas is directly proportional to its absolute temperature.
