Because they're not confident enough to confirm it's indeed true but they will support it for they believe it's correct.

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

What is true about all plutons? They form near Earth’s surface. They form below Earth’s surface. They cut across other rock laye
pishuonlain [190]

<u>Answer:</u> The correct answer is that they are formed below Earth's surface.

<u>Explanation:</u>

Plutons are defined as the intrusive igneous rocks named as plutonic rocks which are formed when the magma gets cools down slowly and solidifies below the Earth's surface.

It is different from volcanic rocks which are formed when lava gets cools down and solidifies on the Earth's surface.

Hence, the correct answer is that they are formed below Earth's surface.
