Answer:the initial composition of the reactants is
40cm^3 of CH4
40cm^3of H2
100cm^3 of H2O
Explanation:
Balanced reaction is
CH4 +H2+5/2O2______
CO2 +3H2O
Excess KOH at room temperature absorbs CO2 whose volume is given by 40cm^3 i.e the volume by which the solution decreases
So using Gay lussac combining ratio which states that gases combine in volumes that are in simple ratio to each other if gases.
Since CO2 in the equation is 1 mole
Means 1mole represent 40cm^3
So CH4:H2:O2 are in ratio of 1:1:5/2=(40:40:100)cm^3 respectively.
Many of the men may believe that they are fair and unbiased against women.
Many of the women may already believe that they face biases.
<h3>What is confirmation bias ?</h3>
The propensity to seek for, understand, favor, and remember information that supports or confirms one's preexisting opinions or values is known as confirmation bias. People exhibit this bias when they choose facts that support their opinions while rejecting those that contradict them or when they interpret ambiguous facts as supporting their preexisting beliefs. Although confirmation bias cannot be completely avoided, it can be controlled, for instance, by critical thinking education and training.
Confirmation bias has been linked to poor decisions in the scientific, organizational, financial, and political spheres. These biases can preserve or reinforce views in the face of contradictory data and contribute to overconfidence in personal opinions.

Dissociation of NaCl in water is given as below,
NaCl ₍s₎ → Na⁺ ₍aq₎ + Cl⁻ ₍aq₎
According to this balanced equation the moles on RHS and LHS are as,
Moles on LHS,
NaCl ₍s₎ = 1 Mole
Moles on RHS,
Na⁺ ₍aq₎ = 1 Mole
Cl⁻ ₍aq₎ = 1 Mole
Result:
<span>When one mole of sodium chloride dissociates in water, it produces 2 Moles of Ions.</span>
The molar mass of gas = 206.36 g/mol
<h3>Further explanation</h3>
In general, the gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.082 l.atm / mol K
T = temperature, Kelvin
mass (m)= 2.89 g
volume(V) = 346 ml = 0.346 L
T = 28.3 C + 273 = 301.3 K
P = 760 mmHg=1 atm
The molar mass (M) :
Sodium is a metal and bromine is a nonmetal so they form an ionic compound
nonmetals and nonmetals form covalent compounds
