Given a chemical reaction, methane (CH4) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). Which of these represent an unbalanced equation with the correct chemical formulas?

CH4 + O2 CO2 + H2O

CH4+ CO2 O2 + H2O

CO2+ H2O CH4+ O2

CH4 O2 + CO2+ H2O

anonymous · Answer

Equation 1 it is unbalanced as it has to be CH4  +2O2    Makes CO2 + 2H2O

Complete combustion
Complete combustion (given sufficient oxygen) of any hydrocarbon produces carbon dioxide and water. 
CH4+O2-->CO2+H2O

When a strip of zinc is placed in a solution of silver nitrate, Zn replaces Ag to form zinc nitrate, and metallic silver is formed. How many moles of silver will be generated if 1.30 moles of zinc is placed into the silver nitrate solution?

2AgNO3 + Zn → 2Ag + Zn(NO3)2

    0.65 moles

    1.30 moles

    2.60 moles

    6.20 moles
