<span>The type of map that shows the type and age of rocks in an area is called a Geologic Map. A geologic map is a special-purpose map that represents the distribution of diverse types of rocks, as well as locations of different geologic structures such as faults and folds. This map is the main source of information for various aspects of land-use planning, especially in the placement of transportation systems and buildings. Although they are typically depicted as two-dimensional, they can also be illustrated in its third or fourth dimension depending on the type of information needed to be taken. </span>

What solid depends on hydrogen bonds to hold it together?

notka56 [123]

Answer: The force of attraction present between the solids depends on the type of solid.

Explanation:

For e.g. if solid is ionic solid, then the ionic forces hold on the solid molecules. And these forces hold together and form solid. When it comes to hydrogen bonding stronger the hydrogen bonding, more together the molecules and it become solid.

1. convert 8.43 x 1025 atoms of Fe to moles

Luba_88 [7]

Answer:

The number of moles of Fe are, 139.9 moles.

The number of moles of CO are, 7.89 moles.

The number of moles of Al are, $4.04\times 10^{-4}$ moles.

Explanation :

As we know that 1 mole of substance contains $6.022\times 10^{23}$ atoms or molecules.

Part 1:

As, $6.022\times 10^{23}$ atoms of Fe present in 1 mole

So, $8.43\times 10^{25}$ atoms of Fe present in $\frac{8.43\times 10^{25}}{6.022\times 10^{23}}\times 1=139.9$ mole

Thus, the number of moles of Fe are, 139.9 moles.

Part 2:

As, $6.022\times 10^{23}$ molecules of CO present in 1 mole

So, $4.75\times 10^{24}$ molecules of CO present in $\frac{4.75\times 10^{24}}{6.022\times 10^{23}}\times 1=7.89$ mole

Thus, the number of moles of CO are, 7.89 moles.

Part 3:

As, $6.022\times 10^{23}$ atoms of Al present in 1 mole

So, $2.43\times 10^{20}$ atoms of Al present in $\frac{2.43\times 10^{20}}{6.022\times 10^{23}}\times 1=4.04\times 10^{-4}$ mole

Thus, the number of moles of Al are, $4.04\times 10^{-4}$ moles.

What is the difference between an atom and ion. What makes an ion an ion?

tresset_1 [31]

Answer:

atoms are neutral or they have equal number of proton and electron but ions can be cation(positively charged) or anion(negatively charged) based on the number of electron the atm lose and gain respectively
