Between between benzene and ethanol , Benzene is the most soluble in hexane. reason been benzene can form a hydrogen bond with hexane, also benzene can form london forces with hexane molecule. In addition benzene can form dipole-dipole interaction with hexane molecules
The amount of carbon combined with oxygen in order to form Carbon Dioxide(CO₂) is 12 grams
The Law of Multiple proportions is one of the basic laws in chemistry along with the Law of Definite proportion. This law was proposed by John Dalton in 1803. The law states that if two elements react to form one or more compounds then the ratio of masses of both the elements is in the ratio of small whole numbers.
It is known that Carbon can form two different compounds while reacting with Oxygen that is: Carbon Monoxide, Carbon Dioxide. For Carbon Monoxide, 12g of Carbon needs to react with 16g of Oxygen. Whereas, In Carbon Dioxide, 12g of Carbon needs to react with 32g of Oxygen. So the mass of Carbon is equal in both cases is 12g.
C(12g) + O(16g) ⇒ CO (Carbon Monoxide)
C(12g) + 2O(32g) ⇒ CO₂ (Carbon Dioxide)

Answer:
Explanation:
Hello,
In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:
So we solve for 
by firstly computing the initial pressure:
Finally, we can compute the work by using the following formula:
Best regards.
Answer:
2M
Explanation:
M=mol/L
1. Find moles of CoCl2
mass of substance/molar mass = 130/129.833 = 1.001 mol
3. Substitute in molarity equation
M=(1.001/0.5)
M= around 2M
