1. Carbon monoxide, CO(g), is a deadly gas that takes the place of oxygen molecules
in the blood. If you are smoking, the concentration of carbon monoxide that reaches
your lungs is approximately 200 ppm. Determine the mass of CO(g) that would be
present in a sample of air having a mass of 9.69 (approximately one breath).

1= c 2= a or d3 = idk sorry 4= c5= c

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.
