The study of all chemicals containing carbon is organic chemistry.
A. the height of the cactus plants
Explanation:
The dependent variable in this experiment designed to test this hypothesis is the height of the cactus plants.
In a hypothesis statement, we can always deduce the dependent and independent variables.
- Independent variables do not rely on other variables. They are usually the cause of the phenomenon observed in an experiment. In this experiment, it is the rainfall on the cactus plant.
- Dependent variable is that variable that relies on the independent variable. It is usually the effect of changes in independent variable.
- The height of the cactus plant depends on the amount of rainfall in an area.

Given:
0.607 mol of the weak acid
0.609 naa
2.00 liters of solution
The solution for finding the ph of a buffer:
[HA] = 0.607 / 2.00 = 0.3035 M
[A-]= 0.609/ 2.00 = 0.3045 M
pKa = 6.25
pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
