4FeS2 + 11O2 yields 2Fe2O3 +8SO2. I don't understand this equation. FeS2 leads me to believe that the Fe here has a charge of +2 but in the product it appears to have a charge of +3 judging by the formulas. How is this possible
Recognize each of the following reactions as synthesis, decomposition, single replacement, double replacement, neutralization, or combustion. A)H3PO4 + 3NaOH -> Na3PO4 + 3H20 This reaction is known as Neutralization. B)P4 + 5O2
I need an idea to show single replacement reaction and double replacement reaction. The example the teacher used was a single guy + couple dancing - Girl swithes partners. I have to be able to draw the idea....help!!
a. Cl2 + 2NaI → 2NaCl + I2 This is a single replacement reaction. b. 2K + 2HCl → 2KCl + H2 This is a single replacement reaction. c. N2 + 3H2 → 2NH3 This is a synthesis reaction. d. 2KClO3 → 2KCl + 3O2 This
