Answer:
Graduated cylinder
Explanation:
A graduated cylinder is used routinely for measuring volume and is considered more accurate than a beaker because of the permanently-marked incremental graduations incorporated in the clear cylinder.

The concentration of NO2 is 0.054 M and that of N2O4 is 0.003 M.
<h3>Equilibrium constant</h3>
The equilibrium constant shows the extent to which reactants are converted into products.
We have the reaction; N2O4⇌2NO2 and Kp = 4.5. Setting up the ICE table, we have;
N2O4 ⇌ 2NO2
I 0. 0550 0
C -x +x
E 0. 0550 - x x
Given that;
Kp = [NO2]^2/[N2O4]
4.5= (x)^2/0. 0550 - x
4.5(0. 0550 - x) = x^2
0.2475 - 4.5x = x^2
x^2 + 4.5x - 0.2475 = 0
x=0.054 M
The concentration of the required NO2 gas at equilibrium is 0.054 M and that of N2O4 is 0.003 M.

Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
Answer:
The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages
