Answer:
Activation of the ring towards substitution: NH2, OCOCH3
Withdrawal of electrons through resonance. COOH, SO3H
Explanation:
During electrophilic substitution, certain substituents may activate or deactivate the benzene ring.
Substitients that activate or deactivate the benzene ring may do so via resonance or inductive effect.
Groups such as -NH2 and OCOCH3 activate the ring via resonance while groups such as -SO3H and -COOH deactivate the ring via resonance.
From Grahams Law the rates of effusion of two gases are inversely proportional to the square roots of their molar masses at the same temperature and pressure.
Therefore; R1/R2 = √mm2/√mm1
The molecular mass of Carbon dioxide is 44 g
Hence; 1.8 = √(44/x
3.24 = 44/x
x = 44/3.24
= 13.58
Therefore, the molar mass of the other gas is 13.58 g/mol
Answer:
I belive about 3 days.
Explanation:
To the naked eye, the full moon lasts about three days, but in reality, it is a full moon for just an instant before it begins to wane. The moon takes just under one month an average of 29 1/2 days to complete its phases.
Hope this helps!
I’m not sure what this says could you translate it to English please?
The equilibrium constant of reaction, usually denoted as K, is a unit of ratio. The ratio involves concentrations or partial pressures of products to reactants. But you also have to incorporate their stoichiometric coefficients in the reaction as their respective exponents. If K is in terms of concentration, only the substances in their aqueous state are the ones that are included only in the expression. If K is in terms of partial pressures, only the substances in gaseous states are the ones that are included only in the expression. For this problem, it would be in terms of partial pressures. To properly show you how it's done, consider this equilibrium reaction:
aA (g) + bB (g) ⇆ nN (g)
The equilibrium constant for this reaction is:
K = [N]ⁿ/[A]ᵃ[B]ᵇ
where the [] brackets denotes partial pressures of the substances
Particularly, for the reaction <span>a(g)⇌b(g), the K expression would be
</span>K = [B]/[A]
So, if K is less than one, that means that the numerator is less than the denominator. It follows that the partial pressure of reactant A is greater than product B. Since A is greater, then the more favorable direction would be the forward reaction. The δG°rxn would then be negative in value. So δG°rxn < 0.
To explain, δG°rxn is a criterion for spontaneity. If δG°rxn is negative, the reaction is spontaneous. If δG°rxn is positive, it is non-spontaneous. Since the favorable reaction is the forward reaction, it is spontaneous.
