Hello!
First, HNO₃ dissociates in the following way:
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
Next, there is a neutralization reaction with Methylamine:
H⁺(aq) + CH₃NH₂(aq) → CH₃NH₃⁺(aq)
Finally, the formed methylammonium ion weakly dissociates in the following way:
CH₃NH₃⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + CH₃NH₂ (aq)
From this sequence of reactions, we can see that the resulting solution would be slightly more acidic than the initial one, as the buffer solution resists the addition of strong acid.
Have a nice day!
Boyle’s Law P1V1 = P2V2
P1 = 0.80 atm V1 = 1.8 L
P2 = 1.0 atm V2 = ??
(.8 atm)(1.8 L) = (1.0 atm)(V2)
1.44 atm x L = 1 atm V2
Answer: 6 valence electrons
Explanation: the valence electrons and group are always the same, but when the group numbers are 10 and above, they would be the first number. For example, every element in group 16 has 6 valence electrons.
Answer:
1.11407×10^25
Explanation:
18.5 x 6.022*10^23= 1.11407×10^25
(Avogadro's number)
Answer is: <span>all of them are hard and dense metals.
Beryllium, magnesium,calcium and strontium are a</span>lkaline earth metals. The elements have very similar properties. Alkaline earth metals<span> have in common an outer s- </span>electron shell (two electrons). Strontium has greatest density of this four elements.
