Answer:
6.7970 g
Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pOH of the basic buffer solution as:
pOH = pK + log[acid] / [base]
Where K is the dissociation constant of the base.
Base dissociation constant of the ammonia = 1.8×10⁻⁵
pK = - log (Kb) = - log (1.8×10⁻⁵) = 4.75
Given concentration of base = [base] = 0.273 M
pH = 10.150
pOH = 14 - pH = 14 - 10.150 = 3.85
So,
3.85 = 4.75 + log[acid]/0.273
[Acid] = 0.0347 M
Given that Volume = 2 L
So, Moles = Molarity × Volume
Moles = 0.0347 × 2 = 0.0694 moles
Molar mass of ammonium bromide = 97.94 g/mol
Mass = Moles × Molar mass = (0.00775 × 97.94) g = 6.7970 g

WHERE IS THE EQUATION ?????
Explanation:
Answer:
Explanation:
{\displaystyle {}^{n}x}{}^{n}x, for n = 2, 3, 4, …, showing convergence to the infinitely iterated exponential between the two dots
In mathematics, tetration (or hyper-4) is an operation based on iterated, or repeated, exponentiation. It is the next hyperoperation after exponentiation, but before pentation. The word was coined by Reuben Louis Goodstein from tetra- (four) and iteration.
Under the definition as repeated exponentiation, the notation {\displaystyle {^{n}a}}{\displaystyle {^{n}a}} means {\displaystyle {a^{a^{\cdot ^{\cdot ^{a}}}}}}{\displaystyle {a^{a^{\cdot ^{\cdot ^{a}}}}}}, where n copies of a are iterated via exponentiation, right-to-left, I.e. the application of exponentiation {\displaystyle n-1}n-1 times. n is called the "height" of the function, while a is called the "base," analogous to exponentiation. It would be read as "the nth tetration of a".
Tetration is also defined recursively as
{\displaystyle {^{n}a}:={\begin{cases}1&{\text{if }}n=0\\a^{\left(^{(n-1)}a\right)}&{\text{if }}n>0\end{cases}}}{\displaystyle {^{n}a}:={\begin{cases}1&{\text{if }}n=0\\a^{\left(^{(n-1)}a\right)}&{\text{if }}n>0\end{cases}}},
allowing for attempts to extend tetration to non-natural numbers suc
Answer:
Independent variable: DIFFERENT TEMPERATURE
Explanation:
The independent variable of an experiment is the variable that the experimenter changes or manipulates in order to effect an outcome or response in the measured variable/dependent variable.
In this experiment, a scientist wants to determine how temperature affects photosynthesis. He sets up the experiment by adding 20ml of water at different temperatures to three test tubes. Hence, the independent or experimental variable is the DIFFERENT TEMPERATURES GIVEN TO EACH PLANTS IN THE TEST TUBE because it is what the experimenter changes in order to effect a measurable outcome i.e. oxygen released in each balloon as a result of photosynthesis, which is the dependent variable
