a sample may contain na2co3 (105.989 g/mol), nahco3 (84.007 g/mol), naoh (39.977 g/mol) or a compatible mixture of these bases. a 0.8412-g sample titrated directly to the methyl orange endpoint required 45.38 ml of 0.1320 m hcl. another 0.8412-g sample was titrated to the phenolphthalein endpoint with the same acid. it required 28.32 ml acid.

what is/are the percentage(s) of each of the base(s) in the sample?

can i get a solution that separates the bases, if possible

Which atom or ion is the largest? a. k b. k+ c. ca d. ca2+ e. li

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
