Answer:

the empirical formula is H_2NO_2

Explanation:

The empirical formula is

The following information is given

It contains 29.17 mass percentage of N

4.20 mass percentage of H

And, 66.63 mass percentage of 0

Now based on the above information, the empirical formula is H_2NO_2

hence, the same is to be considered and relevant too

Answer:

The given equation obey the law of conservation of mass.

Explanation:

Chemical equation:

2LiOH + CO₂  →   Li₂CO₃ + H₂O

There are equal number of atoms of oxygen, hydrogen and lithium on both side of equation so it obey the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

2LiOH                +            CO₂         →         Li₂CO₃           +                    H₂O

2(6.941 + 16 + 1)  +          12+32                   6.941×2 + 12 + 3×16     +       18

47.882 + 44                                                  13.882 +12+48   +   18

91.882 g                                                                91.882 g

The mass of reactants and product are equal.

You measure the absorbance of your extracted curcumin solution and realize that the solution is too concentrated. What made you
zepelin [54]

If the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high.

Spectrometry measures the interaction of light with molecules. The absorbance refers to how much light that interacts with molecules of the substance. The more the concentration of the substance the higher the absorbance of the solution.

Hence, if  the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high. An unusually high absorbance tells us that the solution is too concentrated.

Wine has a pH of 3, which means it is __________ times more acidic than tomatoes, which have a pH of 4.
Natasha2012 [34]

Answer:

10

Explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,  

pH = - log [H⁺]

Thus, from the formula, more the concentration of the hydrogen ions or more the acidic the solution is, the less is the pH value of the solution.

Thus, solution with pH = 3 will be more acidic than solution with pH =4  

Thus, concentration of the [H⁺] when pH =3

3 = - log [H⁺]

[H⁺] = 10⁻³ M

For pH = 4, [H⁺] = 10⁻⁴ M

<u>hence, pH = 3 is 10 times more acidic than pH = 4</u>
