Hydrocarbons may vary from state to state depending on the length of the carbon chain. For methane to butane, they are usually in gas form. Starting from pentane, they are in the liquid form. For very long carbon chains, that occur as solids. Now, it depends if the pentane is in a nonpolar liquid or polar liquid. Since pentane is nonpolar, it is miscible in the liquid solvent. The movements would most likely be free flowing. But if he solvent is polar, the molecules would repel with one another. In the end, it will form two liquid phases, on for the pentane and one for the polar solvent.
Answer:
391.462 g
Explanation:
First, let's calculate the total mass of the solution by the definition of density (d)
d = m/V, where <em>m</em> is the mass in gram and <em>V</em> the volume in mL. So for the given solution
1.285 = m/800
m = 1028 g
The mass of sulfuric acid will be:
0.3808x1028 = 391.462 g
Answer:
2 that is Calcium (Ca) and Manganese (Mn)
Explanation:
Add dithizone in chloroform and look for a red complex formation.
Answer: the scientist should ensure that the volume is measured in dm3(or L), the pressure in atm, the temperature in Kelvin and use the gas constant 0.082atm.dm3.K^-1.mol^-1
