Answer:
is simple apply formula dude.
Answer:
The answer to your question is m = 3.2
Explanation:
Molality is defined as the number of moles of a solute dissolved in a mass of solvent (kg).
Data
moles of solute = 43.6
mass of solvent = 13.5 kg
Formula
Molality = 
Substitution
Molality = 
Simplification and result
Molality = 3.2
Answer:
Homologous structure
Explanation:
Homologous structures come from same ancestors but have different functions.
The equilibrium expression shows the ratio
between products and reactants. This expression is equal to the concentration
of the products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
<span>H2CO3(aq) + H2O(l)
= H3O+(aq) + HCO3-1(aq)
Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>
