Hexane and heptane are miscible with each other in all proportions. In making a solution of them, is the entropy of the system i
Damm [24]

Answer: Option (a) is the correct answer.

Explanation:

A miscible solution is defined as the one in which two or more than two components are soluble with each other.

So, when hexane is added to heptane then both of them will mix with each other and hence they are miscible. This mixing will lead to formation of more number of ions into the solution as a result, more will be the disorder present in the solution.

As entropy is the degree of randomness present.

Hence, we can conclude that a solution of hexane and heptane will lead to an increase in entropy.

How many kilowatt hours does it take to lift an apple that weighs 100g 1 meter.(use 9.8 kg
kati45 [8]

Answer:

The answer to your question is   Power = 0.98 W  or 9.8 x 10⁻⁴ kW

Explanation:

Data

Power = ?

mass = 100 g = 0.1 kg

distance = 1 m

gravity = 9.8 m/s²

Formula

Power = Work / time

Process

1.- Calculate the Work

      Work = Force x distance

      Force = mass x gravity

      Work = mass x gravity x distance

      Work = (0.1 kg)(9,8)(1)      

      Work = 0.98 J

2.- Calculate the power

       Power = 0.98 J / 1 h

       Power = 0.98 W  or 9.8 x 10⁻⁴ kW

Which sublevels hold valence electrons?
pogonyaev

Answer:

The Periodic Table can be divided into s, d, p, and f sublevel blocks. For elements in the s sublevel block, all valence electrons are found in s orbitals. For elements in the p sublevel block, the highest energy valence electrons are found in p orbitals.
