Answer:
3) The relative concentrations of each gas must remain constant.
4)The concentration of each gas will not change.
Explanation:
- For the equilibrium system:
<em>X₂ + Y₂ ⇄ 2XY,</em>
The no. of moles of gases in each side is constant; there is 2 moles of gases at reactants side and 2 moles of gases at products side.
So, changing the volume will not affect on the equilibrium system.
<em>So, the right choice is:</em>
3) The relative concentrations of each gas must remain constant.
4)The concentration of each gas will not change.
The molarity of a hydrochloric acid solution : 0.32 M
<h3>Further explanation </h3>
Titration is a procedure for determining the concentration of a solution by reacting with another solution which is known to be concentrated (usually a standard solution).
Titrations can be distinguished including acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases is used.
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence
1 ⇒HCl (valence=1, HCl ⇒H⁺+Cl⁻, one H⁺)
2⇒Ca(OH)₂(valence=2, Ca(OH)₂⇒Ca²⁺+2OH⁻, two OH⁻)
M₂=0.1 M
V₂=48 ml=0.048 L
V₁=30 ml=0.03 L

This might be wrong,but im pretty sure its 0.10 m

Q2. All of the above
The geometric arrangement of one of two or more compounds that have the same number and type of atoms but differ drastically from one another.
<h3>What is structural isomers?</h3>
The term "structural isomer," also known as a "constitutional isomer," refers to a group of two or more organic compounds that share the same chemical formula but have different structures. In spite of having the identical chemical formula, the two molecules below differ in where the methyl group is located.
The most extreme kind of isomerism is structural isomerism. As contrast to stereoisomerism, which merely differs in the relative spatial arrangement of the atoms while maintaining the identical atoms and bonding structure. The enantiomers, which have molecules that are mirror images of one another, and the cis and trans forms of 2-butene are examples of the latter.
Skeletal isomers, positional isomers (also known as regioisomers), functional isomers, tautomers, and structural topoisomers are some of the different classes of structural isomers.
