Answer:
To balance the reaction, we should put a 4 in front of Al
Explanation:
<u>Step 1:</u> Data given
AI+3O2->2AI2O3
<u>Step 2:</u> Balance the equation
On the right side we have 2*3 = 6 oxygen atoms
On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced
On the right side we have 2*2 = 4 Al atoms
On the left side we have only 1 Al atom
We should multiply this by 4 (place a 4 in front of the Al)
4AI + 3O2 → 2AI2O3
Now al atoms are balanced on both sides.

Answer:
See explanation and image attached
Explanation:
The reaction of (R)-2-chloro-3-methylbutane with potassium tert-butoxide yields a monosubstituted alkene .
Since the base is bulky, the Hoffman product predominates because attack occurs at the less hindered carbon atom to yield the major product as shown.
The alkene reacts with HBr at the secondary carbon atom to yield a carbocation intermediate which is flat and planar. Attack on either face of the carbocation yields a racemic mixture of the (2R) and (2S) products.
Rearrangement of the carbocation to yield a tertiary carbocation gives the 2-bromo-2-methyl butane product as shown in the image attached.
A kilometer is equal to 1000 meters and a meter is equal to 100 centimeters, so:
1 km = 100000 cm
1 cm = 0,00001 km
Just multiply or divide it by 100000.
