Iron has a density of 7.86 g/cm3. Calculate the volume (in dL) of a piece of iron having a mass of 4.59 kg .
Answers
k = 10^3
1 cm^3 = 10^-2 dL
Solutions
Density = (mass)/(volume)
Volume = (mass)/(density)
Volume = (4.59 × 10^3g)/(7.68g/cm³)
Volume = 583.97 cm³
Volume = (583.97 cm³)(10^-2 dL/1 cm³)
So volume = 5.84 dL approximately

How does the carbonyl group increase the reactivity of carboxylic acids?
Answers
Answer:
The relative reactivity of carboxylic acid derivatives toward nucleophile substitutions is related to the electronegative leaving group's ability to activate the carbonyl. The more electronegative leaving groups withdraw electron density from the carbonyl, thereby increasing its electrophilicity.

If a stronger solution of sodium bicarbonate was used in beaker C, would it require more or less hydrochloric acid to neutralize and why?
Answers
Part A; A stronger solution of sodium bicarbonate require more hydrochloric acid will be required
Part A; The reason why more HCl is required is due to the presence of more hydroxyl ions in the solution
The reason arriving at the above responses are as follows;
Part A
Sodium bicarbonate, NaHCO₃, is baking soda = A basic salt; has the capacity to deprotonate water
Hydrochloric acid, HCl = An acid
The reaction between sodium bicarbonate and hydrochloric acid is presented as follows;
NaHCO₃ + HCl → CO₂ + H₂O + NaCl
The equation for the ionic reaction is as follows;
Na⁺(aq) + HCO₃⁻(aq) + H⁺(aq) + Cl⁻(aq) → Na⁺(aq) + Cl⁻(aq) + H₂O(l) + CO₂(g)
In water, we have;
HCO₃⁻(aq) + H₂O(l) ⇄ H₂CO₃(aq) + OH⁻(aq)
The presence of a stronger solution of sodium bicarbonate, will produce more hydroxyl ions, OH⁻(aq), which will require, more HCl to neutralize
Therefore, if a stronger solution of sodium bicarbonate was used, more hydrochloric acid will be required
Part B
The solution of stronger sodium bicarbonate will contain a higher concentration of hydroxyl ions and therefore, require more HCl, to neutralize
