A positive feedback is a process that occurs in a feedback loop which exacerbates The effects of a small disturbance. That is, the effects of a pertubation on a system include an increase in the magnitude of the pertubation.
Answer:
The pressure inside the chamber is 0.132 atm
Explanation:
Step 1: Data given
The initial volume = 0.027 L
The initial pressure = 1.0 atm
The volume changes to 0.205 L
Step 2: Calculate the pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 1.0 atm
⇒with V1 = the initial volume = 0.027 L
⇒with P2 = the changed pressure = TO BE DETERMINED
⇒with V2 = the changed volume = 0.205 L
1.0 atm *0.027 L = P2*0.205 L
P2 = 0.027/0.205
P2 = 0.132 atm
The pressure inside the chamber is 0.132 atm

{\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:
12.044 ×10²³ molecules of HCl
Explanation:
Given data:
Number of moles of MgO = 1 mol
Number of molecules of HCl react = ?
Solution:
Chemical equation:
MgO + 2HCl → MgCl₂ + H₂O
with 1 mole of MgO 2 moles of HCl are react.
Number of molecules of HCl react:
1 mole contain 6.022×10²³ molecules
2 mol × 6.022×10²³ molecules / 1 mol
12.044 ×10²³ molecules
