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: We know, by law of constant proportion :
Chemical compounds always contains its component in constant fixed ratio or in fixed percentage without depend on its source, method of preparation and mass of compound.
Therefore, percentage of oxygen is same for any mass.
Hence, this is the required solution.
Explanation:
Answer:
The final volume is 6.4 L.
Explanation:
Dilution is reducing the concentration of a chemical and is achieved by adding more solvent to the same amount of solute. In other words, dilution is the procedure that is followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.
In a dilution the amount of solute does not vary, and as only more volume (and mass) of solvent is being added, the concentration of the solute decreases.
In a dilution the expression is used:
Ci*Vi = Cf*Vf
where:
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
In this case:
- Ci: 8 M
- Vi: 2 L
- Cf: 2.5 M
- Vf: ?
Replacing:
8 M* 2 L= 2.5 M* Vf
Solving:
Vf=6.4 L
<u><em>The final volume is 6.4 L.</em></u>
Answer:
<h3>2CH3COOH(l)⇒⇒⇒⇒(CH3COOH2)+ + (CH3COO)-</h3>
Explanation:
Remember that, ionization is a process by which an atom or a molecule receives a negative or positive charge by gaining or losing electrons during a chemical reaction. However the auto-ionization reaction for acetic acid the two solvent molecules (CH3COOH2)+ + (CH3COO-) collide and a proton is transferred between them.
