Answer:
Most viscous to least viscous: 
Explanation:
For hydrocarbons, viscosity increases with increasing molar mass. Because increasing molar mass signifies increase in number of electrons in molecules.
We know that in non-polar hydrocarbons, only van der waal intermolecular force exists. Van der waal force is proportional to number of electrons in a molecule.
Therefore with increasing molar mass, van der waal force increases. hence molecules gets more tightly bind with each other resulting increase in viscosity.
Here molar mass order :
Therefore viscosity order :
Well, the sun heats up colder areas, the temperature difference causes wind. (sorry if wrong)
Answer:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Explanation:
<span>The atmosphere is composed
mainly of air molecules. And air molecules consist of 21% oxygen and 79%
nitrogen. Oxygen is used for a lot of things. It used for cellular respiration,
for humans to breathe and other complex chemical reactions that needs oxygen. Nitrogen
is one of the important nutrients mostly used in the soil of the plants. It is
used for protein synthesis. Nitrogen is also absorbed by the plants from the
and the soil to complete the necessary reactions. </span>
Answer:
<h3>The answer is 2 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.204 × 10²⁴ atoms of gold
We have
We have the final answer as
<h3>2 moles</h3>
Hope this helps you
