How many iron atoms are present in 3.0 mol of iron metal? Group of answer choices 18 .06 x 1023 iron atoms
6.02 x 1023 iron atoms
12.04 x 1024 oxygen atoms
6 potassim atoms

non of the above lol , 3.77 moles of Fe contain 2.27x1024 atoms fe

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

the movie was based there, and all the animals and characters are native.
