Answer:
Endothermic. The energy is flowing into the molecules causing them to break apart and the ice pop change state.
<span>e.sr⁺(g) → sr2⁺(g) + e⁻
When remove first electron became Sr</span>⁺, second Sr²⁺.
There are 2 significant figures
Answer:
CH3CH=NH2+>CH3CH2NH3+
Explanation:
If we look at the both species under review, we will realize that they are both amines hence they possess the polar N-H bond.
Electrons are ordinarily attracted towards the nitrogen atom hence making both compounds acidic. It is worthy of note that certain features of a compound may make it more acidic than another of close structural proximity. 'More acidic' simply means that the proton is more easily lost.
CH3CH=NH2+ contains an sp2 hybridized carbon atom which is highly electronegative and further withdraws electron density from the N-H bond thereby leading to a greater acidity of CH3CH=NH2+ compared to CH3CH2NH3+
