They both have different textures. they are completely different substances with each exhibiting unique properties. they both have different atoms involved on their structures which is the cause of the differing properties. hope this helps, have an amazing day :)

Lead is heavier and more resistant. Plastic foam is light and can easily be broken

Convert Au(clo3)2 to s name
Sholpan [36]
Since Au is a symbol for Gold, and once you split the name into to giving each ion its charge... you'll see that this compound has Au+2 and Cl03- .... so  the name would be 

Gold(II) Chlorate

Hope this helps!

Compound X has a molar mass of 266.64 g/mol and the following composition: aluminum 20.24% chlorine 79.76% Write the molecular f
N76 [4]

Answer:

Explanation:

Assume we have 100g of this substance. That means we would have 20.24g of Cl and 79.76g of Al. Now we can find how many moles of each we have:

\frac{79.76 \:g}{35.45 \: g/mol} = 2.25 mol of chlorine

\frac{20.24 \: g}{26.98 \: g/mol} = 0.750 mol of Al.

To form a integer ratio, do 2.25/0.75 = 2.99999 ~= 3.

So the ratio is essentially Al : Cl => 1 : 3. To the compound is possibly AlCl_3.

However, it says it has a molar mass of 266.64 g/mol, and since AlCl3 has a molar mass of 133.32, it must be Al_2Cl_6.

Actually this molecule isn't exactly AlCl3 (which is ionic). Al2Cl6 forms a banana bond where Cl acts as a hapto-2 ligand. But that's a bit advanced. All you need to know is X = Al2Cl6

At 298 K, oxygen (O2) and ozone (O3) have different properties because their
Paha777 [63]

Answer: (3) molecules have different molecular structures.


Explanation:


1) Oxygen (O₂) and ozone (O₃) are allotropes of each other.


2) Allotropes are different structural forms of a same element with different structures and properties, when they are in the same state: solid, liquid, gas.


3) The bonds is what define the structure and properties of the substances, so since O₂ has only two bonds and O₃ has three bonds, the properties and behaviors of the element are different.


4) Other example of allotropes are graphite and diamond: two different forms of carbon. Both, graphite and diamond are formed only by carbon atoms, but they are bonded differently so, as you know, diamond and graphite have different properties: graphite is very soft while diamond is one of the hardest known substances.
