The answer should be...99.318!
In order to <span>complete and balance the following reactions, you should add a Fe into it. So it will look like uo2+ +cr o^2- 7 ـــــــــــــــــــــ uo2+ +cr3+Fe. The answer to the following given statement or missing answer is Fe. </span>
<h2>9. Given : P + O2 = P2O5</h2>
Balanced Chemical Equation: <u>4</u>P + <u>5</u>O2 = <u>2</u>P2O5
<u>Reactant Product</u>
P = (1) 4 | P = (2) 4
O = (2) 10 | O = (5) 10
Reaction Information
Phosphorus + Dioxygen = <u>Phosphorus Pentoxide</u>
Reaction Type: <u>Synthesis</u>
<h2>
10. Given: HCl + NaOH = NaCl + H2O </h2>
<u>Reactant Product</u>
H = 2 | H = 2
Cl = 1 | Cl = 1
Na = 1 | Na = 1
O = 1 | O = 1
