Answer:
B. 4 Fe + 3 0₂---> 2 Fe₂O3
Explanation:
(A) Ir + O₂--> IrO₂ No: Ir is iridium
(B) 4 Fe + 3 0₂---> 2 Fe₂O3 Yes: Fe is iron and O is oxygen, and the equation is balanced.
(C) I+ 0₂ ---> 10₂ No: I is iodine
(D) 3 Ir + 0₂ -> 6 Ir₂03 No: I is iodine

In the most common isotope of fluorine, fluorine-19, it has 19 electrons, 9 protons and 10 neutrons. Hope this helps you! Good luck!!
We are given with the percentage composition of oxygen in an oxide from phosphorus and oxygen equal to 43.6 percent. that is the phosphorus is equal to 56.4 percent. we divide each with the molar mass and divide each with the smaller quantity. P then is equal to 1 and O is equal to 1.5. In this case, the empirical formula is P2O3.

Heat produced per gram of reactant=13.1 KJ
.=13100 J
Actual heart produced=1850 J
By applying unitary method we get the weight of reactant to be x
x=1850/13100
=0.141 gm
Hope this helps
