Answer:
Explanation:
The quantity of moles of ethanol in the solution is:
The mass and volume of ethanol in the solution are, respectively:
The difference between the total volume of water and ethanol mixed to prepare the solution and the actual volume of solution is:
Answer:
Viscosity
Explanation:
The viscosity of the liquid is the independent variable. The flow rate is the dependent variable in this hypothesis.
The statement given is called the hypothesis. It is a form of scientific guess into a phenomenon.
- An independent variable is the cause.
- A dependent variable is the effect produced.
- In this hypothesis, the cause of the various flow rate of the liquid is the viscosity.
- It is therefore the independent variable.
- The flow rate is the dependent variable.
Answer:
From what I personally know, Acenaphthylene 75%. Empirical Formula (Hill Notation): C12H8. CAS Number: 208-96-8. Molecular Weight: 152.19. Beilstein: 774092. EC Number:
Explanation:
Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit. It is a yellow solid. Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence. Acenaphthylene/Formula is C12H8.
I'm not sure if this will help you but this is what I know so I hope it does :)
True because n on both sides are 2 and the hydrogen on both sides are 6
The reaction will be spontaneous if Gibb free energy is negative, according the following relation:
G = H - T*S
where G is Gibbs free energy, T is change of enthalpy , T is temperature and S is change of entropy
In the case of ammonia:
G = -93000 - 356*(-198) = -93000 + 70488 = -22512 j/mol
As G < 0 then the reaction is spontaneous.
