Answer:
.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.
Explanation:
N2O4(g)<--------> 2NO2(g)
At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.
Hydrochloric acid + Sodium hydroxide =Sodium chloride +water
Both carbon 12 and carbon 14 have the same no. of Electrons but the difference is carbon 14 has more neutrons
Answer:
It matters
Explanation:
Pure substance are known to have a sharp freezing point. However, the presence of solute lowers the freezing point of the solvent. The best time to measure the freezing point is when the freezing process is just beginning.
It will be an error to measure the freezing point when the part of the solution has already frozen.
Answer:
a. True
Explanation:
In this reaction, we will have a <u>hydride transfer</u> to the carbon of the carbonyl group, moving the electrons of the double bond towards the oxygen producing a negative charge. The double bond is then regenerated by removing the chlorine atom from the molecule, producing an <u>aldehyde.</u>
Then, another molecule the LiAlH4 transfers another <u>hydride</u> to the carbon of the carbonyl group, again producing a negative charge on the oxygen. Finally, the hydrogen is protonated producing a <u>primary alcohol.</u>
