Answer : There are 7.0 moles of oxygen in the formula.
Explanation :
The chemical formula of nickel tetracarbonyl is Ni(CO)₄.
We can see that there are 4 carbon atoms and 4 oxygen atoms which together form 4 carbonyl (CO) groups.
Therefore the mole ratio of C to O is 1 : 1.
Let us use this as a conversion factor to find moles of oxygen.
We have 7.0 moles of carbon in the formula.
The moles of O can be calculated as,
There are 7.0 moles of oxygen in the formula.
The formal charge on each atom can be known by counting up the number of valence electrons that is present on each atom.
<h3>What is Lewis structure?</h3>
The term Lewis structure is the representation of a compound using its symbols and showing the valence electrons as dots. This question is incomplete as the Lewis structures were not shown.
If it is shown, we can know the formal charge on each atom by counting up the number of valence electrons that is present on each atom.

<span>The volume of iron is obtained from the density formula (density= mass/ volume) given the density and mass. In this case, 4,540 grams of iron and a density of 7.86 g/ml are given. The volume obtained from formula is 493.64 ml or 5.78 dL. </span>
Answer:
[A]²
Explanation:
Since the formation is independent of D, D is 0 order.
Since a quadruples when it is doubled it can be written as
2A^X= 4
To find the unknown power we can assume A= 1 to make the math simple. So When a = 2 (Because you doubled it) raised to X power it will equal 4
so the unknown power is 2
Making the rate law
[a]²[b]⁰
or simply just
[A]²
