please mark me as brainlest
The one that is observed or measured in the experiment, and it is known as the dependent variable.
Answer:
if charge of ion is positive then it will loose electron
if charge of ion is negative it will gain electron
Only one. variable to get a reliable results you only have to change one.
Answer:
45.4 L
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 27.9 L
V₂ = ?
P₁ = 732 mmHg
P₂ = 385 mmHg
T₁ = 30.1 ºC
T₂ = -13.6 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (30.1 + 273.15) K = 303.25 K
T₂ = (-13.6 + 273.15) K = 259.55 K
Using above equation as:


Solving for V₂ , we get:
<u>V₂ = 45.4 L</u>
