Answer:
A buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH.
Explanation:
Answer:equal to rotation period
explanaition i took the quiz and got this one right
I am not positive but my guess is reproducing because it is producing another organism and it sounds like mitosis and that is part of reproducing and part of that entire system of work cells do
I don’t have my notes on me but I’m assuming this questions has to do with the H+ concentration in each compound. The more H+ molecules in a solution, the more acidic it is, the lower it’s pH is. So for the low pH of 4 (most acidic), H2CO3 is the most concentrated since there are the highest number of H+ ions per molecule. For the medium pH of 7 (neutral), HCO3- is most concentrated. For the high pH of 10 (basic), CO3^2- is most concentrated because there are the least number of H+ ions, in this case, none at all.
Lunar eclipses are more wildly visible because Earth casts a much larger shadow on the moon during a lunar eclipse than the moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar!. ;)
