Answer:
b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.
Explanation:
Hello,
In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.
Best regards.
Explanation:
The giant-impact hypothesis is currently the favored scientific hypothesis for the formation of the Moon. Supporting evidence includes: Earth's spin and the Moon's orbit have similar orientations. Moon samples indicate that the Moon's surface was once molten.
The answer would be Felis silvestris lybica
Answer:
The carbon level would be higher because there is less flora and the carbon would be absorbed at a slower rate. There would not be a good plant to carbon ratio to balance out the carbon levels in the atmosphere.
