The solvent for the mixture is water
<em><u>Explanation</u></em>
- <em><u> </u></em>Solvent is substance that dissolves the solute in a solution.
- solvent must be present at a higher percentage as compared to solute.
- water is the solvent in a homogeneous mixture that consists 12% ethanol, 28% methanol and 60% water, since it contain more % than ethanol and methanol.
Answer:
Explanation:
The question must be restated because you can calculate ΔH₂ from the other reactions only if you know the global ΔH, ΔH₁, and ΔH₃.
As stated by Hess’s law, the overall change in the enthalpy, ΔH, of a reaction does not depend of the path followed. Thus, when you have a series of reactions, the net change from the first reaction to the last reaction is equal to the sum of the ΔH values for the individdual reactions:
If you name ΔH₄, the overal change in the enthalpy to convert 1 to 4, but ΔH₁, ΔH₂, and ΔH₃ are the changes of the intermediate reactions that transform 1 in 2, 2 in 3, and 3 in 4, respectively, then, you can write, accordingly to Hess's law, you can write:
Then, assuming you know ΔH₄, ΔH₁, and ΔH₃, you can calculate ΔH₂ clearing from the previous equation:
- ΔH₂ = ΔH₄ - (ΔH₁ + ΔH₃) ← answer
Answer:
7.34 atm
Explanation:
I'm not 100% sure but from the info given, the most likely case is the following:
0.146/0.0203 = 7.192....
7.192... × 1.02 = 7.335... --> 7.34
Answer:
it is d
Explanation:
because if hot magma is hot wonts it is cold down it actly forms it self
Density=mass/volume
density=45/26.4
density=1.7g/ml
