Answer:

1.551\times 10^7 atoms of palladium are to be laid side by side to span a distance of  4.25 mm.

Explanation:

The radius of the palladium atom, r = 137 pm

Diameter of the palladium atom = 2r =  137 pm = 274 pm

Let the number of palladium atoms laid side by side be x

Length of the chain = 4.25 mm = 4.25\times 10^9 pm

1 mm = 10^9 pm

x\times 274 pm =4.25\times 10^9 pm

x=\frac{4.25\times 10^9 pm}{274 pm}=1.551\times 10^7

1.551\times 10^7 atoms of palladium are to be laid side by side to span a distance of  4.25 mm.

Which agents cause both chemical and physical weathering
shutvik [7]
Weathering is the process by which rocks are broken down by either physical or chemical means. Physical weathering involves physical factors that cause mechanical break down of rocks while chemical weathering involves chemical reactions between the contents of the rocks and other factors such air (oxygen). Agents of weathering are the factors that cause or enhance both physical and chemical weathering. Some of these factors cause both physical and chemical weathering these includes water and temperature.

How many moles of oxygen atoms are in 1.2x10^25 diphosphorus pentoxide molecules
insens350 [35]

Answer:

19.9 atoms

Explanation:

Grams --- Moles --- Atoms

You're converting from atoms (molecules) to moles.

You do not have to calculate the mass of "di phosphorus pentoxide."

Since you're already given 1.2x10^25 atoms, you start with that. You need to cancel out the atoms, so you need Avogadro's number as shown in the image.

(This has nothing to do with the problem) But in case if you're wondering, the "di" in phosphorus means there's 2 phosphorus and the "pent" means that there are 5 oxygens. So P2O5. Go to your periodic table, multiply their respective atomic masses. You would multiply phosphorus twice and oxygen 5 times. And add them up to get the overall mass.

I hope this helped!
