Answer:
I'm pretty sure this doesn't really connect with chemistry much but the answer should be <u>Schedule 1 </u> as stated by the Drug enforcement agency.
Answer:
True
Explanation:
The force gets weaker as you move further away from the nucleus. Therefore, the electrons in the outermost energy level have the most energy
Answer:
Blues
Explanation:
Colors of Rainbow => ROYGBIV
Red Orange Yellow Green Blue Indigo Violet
low energy => => => => => => => => => => high energy
low frequency => => => => => => => => => high frequency
long wavelengths => => => => => => => => short wavelengths
Note: All L's on the Left => low, low, long; other end are opposites.
When a solution of Pb(NO3)2(aq) is mixed with a solution of KI(aq), a precipitate of PbI₂ will form; K⁺ and NO₃⁻ are spectator ions.
<u>Explanation:</u>
When an aqueous solution of lead nitrate (Pb(NO₃)₂ is mixed with aqueous solution of potassium iodide (KI), then there is a precipitate formation of lead iodide (PbI₂), and the potassium (K⁺) ion and nitrate (NO₃⁻) ion acts as spectator ions that is ions do not involved in the reaction.
The reaction can be represented as,
Pb(NO₃)₂(aq) + 2 KI (aq) → PbI₂(s) + 2KNO₃(aq)
The ionic equation can be written as,
Pb²⁺(aq) + 2 NO₃⁻(aq) + 2 K⁺(aq) + 2 I⁻(aq) → PbI₂(s) + 2K⁺(aq) + 2NO₃⁻(aq)
On both sides of the equation, we have K⁺ and NO₃⁻ ions, which gets cancelled, and these 2 ions are called as spectator ions.
This seems more like a statement than a question, but if it is true or false, this is true
