katovenus [111]
<span>The correct answer is 1. compound. There are three elements and not just one so it's not element. Mixtures wouldn't have the same properties that you described but these do so it's a compounds. Solution is not a solid thing but rather a liquid one. The two samples are therefore compounds.</span>

Answer:

Average of measurements = 20.97 cm

Explanation:

Given data:

Three measurements of pete's = 20.9 cm, 21.0 cm, 21.0 cm.

Average value of measurements = ?

Formula:

Average of measurements = sum of all measurements / Total number of measurements

Solution:

Average of measurements =  20.9 cm + 21.0 cm + 21.0 cm. / 3

Average of measurements = 62.9 cm / 3

Average of measurements = 20.97 cm

natta225 [31]

Answer:

Most viscous to least viscous: (c)> (b)> (a)

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 : (c)> (b)> (a)

Therefore viscosity order : (c)> (b)> (a)
