Propanone is more soluble in water compared to propane mainly because propanone?

Answers

Answer 1

Answer:

Propanone is more soluble in water compared to propane mainly because propanone cannot hydrogen bond with themselves but can hydrogen bond with water molecules. One of the slightly positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on the oxygen atom of propanone. In order for propane to bond with water, the van der Waals forces must be broken and also the stronger hydrogen bonds of water molecules and it needs a great amount of energy.

Answer 2

Answer:

Answer:

Propanone is polar, and propane is nonpolar.

Explanation:

As we can see in the molecules below, propanone has a polar bond between Oxygen (in red) and the Carbon, because they have very different electronegativities. In the molecule of propane, there are only bonds between carbon and hydrogen, which have close electronegativities, so it's a nonpolar molecule. Water is polar too. The solubility law says that "polar dissolves polar, and nonpolar dissolves nonpolar".

It occurs because the positive pole of water (in the hydrogen) can bond with the negative pole in propanone (in oxygen) forming a hydrogen bond..

WhenÂ a nucleus of ^235 U undergoes fission, it breaks into two smaller, more tightly bound fragments.1) Calculate the binding energy per nucleon for ^235U? (Express with appropriate units)2) Calculate the binding energy per nucleon for the fission product ^137 Cs? (Express in appropriate units)

Answers

1) The binding energy per nucleon is 7.59 MeV/nucleon and 2) The binding energy per nucleon is 8.39 MeV/nucleon.

1) The binding energy per nucleon is as follows:

m_proton + m_neutron + m_electron - m_U

= 92*1.007276466812 + 92*5.4857990943e-4 + 143*1.008664916 - (235.0439299)

= 1.9151 u

= 931.494061 * 1.9151 MeV

= 1784 MeV

= 1784/235 = 7.59 MeV/nucleon

2) The binding energy per nucleon is as follows:

m_proton + m_neutron + m_electron - m_Cs

= 55*1.007276466812 + 55*5.4857990943e-4 + 82*1.008664916 - (136.9070895)

= 1.2338 u

= 931.494061 * 1.2338 MeV

= 1149 MeV

=1145/137 = 8.39 MeV/nucleon

What is the color of methyl orange after it is added to this sample?

Answers

The indicator will lead to a solution that has a red color. Methyl orange is an indicator used in titrations because it changes colors at all pH values. When in acidic solution it is red and in basic it is yellow. A pH of 1 is acidic, therefore a red solution.

Which of the following statements holds true for a chemical change?A. In a chemical change, no new substance is formed
B. In a chemical change, a substance changes its phase
C. In a chemical change, the molecular structure of a substance changes
D. In a chemical change, one substance dissolves into another

Answers

Answer : The correct option is C.

Explanation :

Chemical change : It is defined as a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.

The molecular structure of a substance changes in a chemical reaction is a chemical change.

Change in molecular structure means that there is a breaking and formation of bonds in a molecule.

The example of chemical change in terms of change in molecular structure is the reaction of hydrogen with oxygen.

The reaction of hydrogen with oxygen is,

$H_2(g)+O_2(g)\rightarrow 2H_2O(l)$

In this reaction, the H-H bond is break and O-H bond is form.

c. in a chemical change the molecular structure changes.

If 40.0 g of HCl react with an excess of magnesium metal, what is the theoretical yield of hydrogen?

Answers

The reaction between HCl and Mg is a substitution reaction:
2HCl + Mg --> MgCl2 + H2

The molar mass of HCl is 36.46 g/mol. Converting the amount of HCl,
40 g / 36.46 g/mol = 1.0971 mol

Based on the balanced chemical reaction, the stiochiometric ratio is:
2 mol HCl / 1 mol H2

So,
1.0971 mol HCl (1 mol H2 / 2 mol HCl) = 0.549 mol H2

Converting moles to mass
0.549 mol H2 (2.02 g H2 / mol H2) = 1.108 g H2

The theoretical yield is:
(1.108/40) (100) = 2.77

The yield is 2.77 g H2 per 100 g of HCl
