Answer:

"3. Energy can either be destroyed or created. Its goes from one form to another."  

Explanation:

The third answer choice, "3. Energy can either be destroyed or created. Its goes from one form to another. " is related to the Law of Conservation of Energy from thermodynamics. Is it not a postulate of the Kinetic Molecular Theory.

<u>"1. Average Kinetic Energy of the system is a measure of the temperature of the system."</u>

Postulate of Kinetic Molecular Theory \checkmark

  • The average kinetic energy of the system is measured by its temperature and nothing else

<u>"2. Energy is conserved in the collisions between gas molecules.."</u>

Postulate of Kinetic Molecular Theory \checkmark

  • All collisions between gas molecules are perfectly elastic, meaning no energy is lost

<u>"3. Energy can either be destroyed or created. Its goes from one form to another.</u>

<u />\times NOT a Postulate of Kinetic Molecular Theory

  • Related to Conservation of Energy from thermodynamics

<u>"4. Gases travel in straight line until they collide with other gas molecules"</u>

Postulate of Kinetic Molecular Theory \checkmark

  • All gas molecules will travel in a straight line until they collide with other gas molecules or some object (e.g. a container)

Calculate the % composition of the unknown liquid using your most precise result. It is a mixture of ethanol (D[ETOH] = 0.7890 g
Rufina [12.5K]

% composition of ethanol = 34.51%

% composition of water  = 65.49%

<h3>What is density?</h3>

A material's density is defined as its mass per unit volume.

Given data:

The density of ethanol = 0.7890 g/mL

The density of water = 0.9982 g/mL

The density of mixture = 0.926 g/mL

Let the % composition of ethanol = x

Let the % composition of water = 100-x

Now density of the mixture

\frac{Mass}{Volume}

Mass = \frac{percent  \;of  \;ethanol  \;X  \;density  \;of  \;ethanol  \;+  \\ \;percent  \;of  \;water X  \;density  \;of  \;water}{100}

0.926 = \frac{x X  0.7890 g/mL  \;+  (100-x) X  0.9982 g/mL}{100}

x= 34.51 %

Hence,

% composition of ethanol = 34.51%

% composition of water = 65.49%

How is primary selection different from secondary succession?
PIT_PIT [208]

Answer:

Explanation:

Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.
