A bicarbonate/carbonic acid buffer is present in Coca-Cola, human blood, and chickens. However, chickens also combine the carbonate in their blood with calcium ions to create calcium carbonate for their eggshells. Since chickens do not sweat, they pant in hot weather. Panting helps to reduce the acidity of the blood by blowing out carbon dioxide. What effect would this have on the pH of their blood and the strength of eggshells they produce

Acertain reaction has a activation energy of 54.0 kj/mol. as the temperature is increased from 22c to a higher temperature, the rate constant increases by a factor of 7.00. calculate the higher temperature. c (report only numerical answer)

Which of the following represents the balanced reduction half-reaction from the redox reaction? (2 points) pb + pd(no3)2 yields pb(no3)2 + pd pb yields pd2+ + e- pd2+ + 2e- yields pd pb + e- yields pb 2 pd2+ + 4 e- yields 2 pd

Henry moseley used x-ray experiments to determine the atomic number of elements. how did his discovery contribute to the development of the periodic table? a.it confirmed that elements should be arranged in strict order of increasing atomic mass. b.it led to elements with similar atomic numbers being grouped together. c.it allowed the elements to be placed in strict order of increasing atomic number. d.it showed that the way mendeleev grouped elements together was completely wrong.
