Construction crews sometimes use this reaction for welding underwater structures:
meriva

Answer:

5 moles of iron formed

Explanation:

Given data:

Moles of iron formed = ?

Moles of iron oxide react = 2.50 mol

Solution:

Chemical equation:

Fe₂O₃ + 2Al     →     Al₂O₃ + 2Fe

Now we will compare the moles of iron with iron oxide.

                  Fe₂O₃        :           Fe

                      1             ;            2

                  2.50          :          2×2.50 = 5 mol

Write structural formulas for each of the possible isomers of n-hexene that are formed by moving the position of the double bond
dem82 [27]

Answer : The structural formulas for each of the possible isomers of n-hexene are shown below.

Explanation :

Isomer : It is defined as a molecule have the same molecular formula but the different chemical structure.

There are three structural isomers of n-hexene that is based on the location of the double-bonded carbon atoms with the other atoms.

In n-hexane, 'n' shows that the chain should be straight chain there is no branching.

The three structural isomers of n-hexene are:

(1) 1-hexene

(2) 2-hexene

(3) 3-hexene

Thus, the structural formulas for each of the possible isomers of n-hexene are shown below.

Nutral atoms&charged atoms has equal number of proton a)true B)false​
Alex73 [517]

Answer:

true

Explanation:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral
