Compare the effusion rate of O2 and CO2 gas; which one is faster and by how much? 3. What is the total pressure in a scuba tank containing 225 KPa of O2 and 55 KPa of N2 and 22 KPa of He gases-
4. The atmosphere consists mostly of N2, O2, and Ar gases. If atmospheric pressure is 101 KPa at Aztec then find O2 pressure if N2 is 80.8 KPa and Ar is 1.0 KPa-

The correct answer is "false"

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
