When pure methanol is mixed with water the resulting solution feels warm would you expect this solution to be ideal?Explain

Chemistry
1 answer:
Pepsi [2]3 years ago
5 0

Answer:

No

Explanation:

In ideal solutions, the interactions between solute - solvent are approximately the same as those of solute - solute and solvent - solvent, that is the interactions are to be practically indistintiguishable after disolution.

The moment we have a release of energy (the solution feels warm) we are to conclude that there are strong interactions between the water and methanol molecules so we would expect the solution to be non ideal.

The reason for the interactions is the presence of hydrogen bonds between methanol and water.

What is the empirical formula of a hypothetical compound that is 96%S and 4% H?​
Bess [88]

Explanation:

Let the mass of the compound be 100g.

Mass of Sulfur = 96g.

=> Moles of Sulfur

= 96g / (32.07g/mol) ≈ 3

Mass of Hydrogen = 4g.

=> Moles of Hydrogen

= 4g / (1.008g/mol) ≈ 4

Mole ratio of Sulfur to Hydrogen = 3 : 4,

Empirical formula of compound = S3H4.

What is the number of electrons shared between the atoms in I2 molecule (That is an i not a 1)
labwork [276]
Iodine is one of seven elements that usually form as diatomic molecules. These other "diatomics" are O_2, H_2, F_2, Br_2, N_2, and Cl_2. They typically bond to themselves.

Iodine has seven valence electrons. Using valence shell electron pair repulsion (VSEPR) theory, we can predict the Lewis dot structure for I_2. We see there are fourteen electrons, and we can make a covalent bond, leaving three lone pairs on each atom. The bond replaces two electrons, so the number of electrons shared is two.

Using the Antoine equation, prepare two plots of Psat versus T for Benzene over the range of temperature for which the parameter
Liula [17]

Answer:

Here's what I get.

Explanation:

The Antoine equation is

\log p = A - \dfrac{B }{C+T}

A = 13.7819

B = 2726.81

C = 217.572

I did the calculations and the plots in Excel.

Figure 1 shows the calculations, Figure 2 is the linear plot, and Figure 3 is the log plot.
