1. _C2H5OH + _O2 = _CO2 + _H2O 2. _Zn + _CuSO4 = _ZnSO4 + _Cu
3. _Ca + _AICI = _CaCl2 + _Al
4. _Hg(OH)2 + _H3PO4 = _Hg3(PO4)2 + _H20
5. _H3PO3 +_H3PO4 + _PH3
6. _C25H52 + _O2 = _CO2 + _H20
7. _Au2O3 = _Au + _O₂
8. _KBr + _Cl2 = _KCI + _Br2
9. _C4H10 + _O₂ = CO₂+ _H₂O
10. P4 + O2 = P₂O5​

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.

Element before carbon on the periodic table

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
