Barrier island refers to the large sandbars along the coastline that form

from deposition of sand over long period of time.

<h3>Features of a Sandy environment </h3>

The features of a sandy environment include the following:

Spits

Barrier islands

Tombolos

Barrier Island are formed when sand is deposited over a long time and this

helps to prevent erosion along the coastline area.

How many molecules are in 18moles of CH.

-Dominant- [34]

Answer:

1.08 x 10²⁵molecules

Explanation:

From the mole concept we know that ;

1 mole of any substance contains 6.02 x 10²³ molecules

This number is the Avogadro's number.

So;

18 mole of CH will contain:

Number of molecules of CH = 18 x 6.02 x 10²³ = 1.08 x 10²⁵molecules

The number of molecules is therefore 1.08 x 10²⁵molecules

You are given a cube of lead that is 1.000 cm on each side. The density of lead is 11.35. How many atoms of lead are in the samp

aliya0001 [1]

<u>11.35 g</u><u> </u><u>atoms </u><u>of lead are in the sample.</u>

What does density mean?

The density of an area refers to the quantity of things—which may include people, animals, plants, or objects—there are in it.
Divide the number of objects by the area's measurement to determine density.
A country's population density is calculated by dividing its total population by its area, expressed in square kilometers or miles.

We can calculate the volume of the cube by cubing the side of the cube.

Volume of cube = ( 1.000 cm)³

= 1.000 cm³

We can now determine the amount of lead in the cube by multiplying by the density. Because we know we have a 1.000 cubic centimeter and that lead has a density of 11.35 grams per cubic centimeter, we have 11.35 grams of lead.

= ( 1.000 cm³) ( 11.35 $\frac{g}{cm^{3} }$ )

= 11.35 g

Answer:

Towards the big bully

Explanation:

If a big bully and a small child are involved in a thug of war, it is clear that the bully is stronger than the child and he/she will pull the rope used in the thug of war with a greater force.

By so doing, the ball attached at the centre of the rope will naturally be drawn towards the stronger bully.
