Answer:

The components present in the solution are:

CH₃NH₂

CH₃NH₃⁺

NO₃⁻

Explanation:

CH₃NH₂(aq) + HNO₃(aq) → CH₃NH₃⁺ NO₃⁻

t = 0,

milliequivalent

100*0.25 = <em>25</em>   50*0.25 = <em>12.5</em>

End of reaction:

25 - 12.5 = <em>12.5</em>,  12.5 - 12.5 = <em>0</em>,  25 - 12.5 = <em>12.5</em>

<em />

moles of CH₃NH₂ left    = 12.5x10⁻³ = 0.0125 > 0.001

moles of HNO₃ left        = 0

moles of CH₃NH₃⁺ left  = 12.5x10⁻³ = 0.0125 > 0.001

moles of NO₃⁻ left         = 12.5x10⁻³ = 0.0125 > 0.001

Therefore, the component present in the solution are: CH₃NH₂ , CH₃NH₃⁺ , NO₃⁻

Which element is most likely to gain electrons in a chemical reaction?
tatyana61 [14]
Option 2, Br. I'll go over why all other three options are incorrect.

Option 1 - Krypton is a Noble gas, and so it doesn't need to accept electrons since it has an octet.

Option 3 and 4 - Both Calcium and Barium are alkaline earth metals, and give away electrons, since they only have 2.
