Answer:
The answer is: the body contains chemicals called buffers that resist changes in pH
When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.

The noble gas notation is the short or abbreviated form of the electron configuration.
It means that you use the symbol of the previous noble gas as part of the electron configuration of an element.
The gas noble previous to antimony is Kr, so you do not use Xe to write the electron configuration of Sb.
The gas noble previous to radium is Rn, so you do not use Xe to wirte the electron configuration of Ra.
The gas noble previous to uranium is Rn, so you do not use Xe to write the electron configuration of U.
The gas noble previous to cesium is Xe, so you use Xe to write the noble notation for Sb. This is it: Cs: [Xe] 6s.
Answer: cesium

Answer:
72.3%
Explanation:
The following data were obtained from the question:
Theoretical yield of MgO = 3.43 g
Actual yield of MgO = 2.48g
Percentage yield of MgO =.?
Percentage yield of a reaction can simply be obtained by dividing the actual yield by the theoretical yield multiplied by 100. This is illustrated below:
Percentage yield = Actual yield /Theoretical yield × 100
Thus, we can obtain the percentage yield of MgO as follow:
Theoretical yield of MgO = 3.43 g
Actual yield of MgO = 2.48g
Percentage yield of MgO =.? Percentage yield = Actual yield /Theoretical yield × 100
Percentage yield = 2.48/3.43 × 100
Percentage yield = 72.3%
Therefore, the percentage yield of MgO is 72.3%.
