Answer:
c. salty.
Explanation:
From the question,
The reaction of an acid , i.e hydrochloric acid and a base i.e. , sodium hydroxide takes place , which is a type of neutralization reaction,
Where the acid and a base reacts to give salt along with water .
From the question,
The reaction is as follows -
2 HCl + NaOH → NaCl + H₂O
Hence, the resulting product is a salt ,
Therefore , the resulting solution would taste like salt.
Good JAHAHAHAHHAHAHAHGAHAHAHA HAHAHAHHAGAGAGGAGAHA
I think, the question should by:
When does quenching occur in a chemiluminescence reaction?
Quenching is a process that decreases the fluorescence intensity of any compound while chemiluminescence refers to emission of cold light due to a chemical reaction. Quenching of fluorophore occurs in a chemiluminescence reaction when the fluorescence of the fluorophore is quenched that leads to the decrease in the intensity of the fluorescence.
In terms of energy transfer, quenching occurs when loss of excitation energy of the molecule takes place in a chemiluminescence reaction.
Answer:
3.00 cm
Explanation:
The absorbance can be expressed using <em>Beer-Lambert's law</em>:
A = ε*b*c
Where ε is a constant for each compound, b is the optical path, and c is the molar concentration of the compound.
Now we <u>match the absorbance values for both solutions</u>, because we want the absorbance value to be the same for both solutions:
A = ε * 1.00 cm * 7.68x10⁻⁶M = ε * b * 2.56x10⁻⁶ M
And <u>solve for b:</u>
ε * 1.00 cm * 7.68x10⁻⁶M = ε * b * 2.56x10⁻⁶ M
1.00 cm * 7.68x10⁻⁶M = b * 2.56x10⁻⁶ M
b = 3.00 cm
