CH4(g) +2O2(g)-->CO2(g)+2H2O(g)
An increase in the concentration of O2(g) at constant temperature and pressure will result in?
1. An increase in the concentration of CH4(g)
2.An increase in the concentration of CO2(g)
3.A decrease in the concentration of O2(g)
4.A decrease in the concentration of H2O(g)

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
