When ethyl acetoacetate (CH3COCH2CO2CH2CH3) is treated with one equivalent of CH3MgBr, a gas is evolved from the reaction mixtur
Alik [6]

Answer:

Methane gas is formed in this reaction. After adding aqueous acid, ethyl acetoacetate is reformed through protonation of it.

Explanation:    

CH_{3}MgBr acts as base towards ethyl acetoacetate. Because ethyl acetoacetate contains active methylene group.

Hence  CH_{3}MgBr abstracts a proton from methylene group and being converted to methane gas.

After addition of aqueous acid, conjugate base of ethyl acetoacetate gets protonated and ethyl acetoacetate is reproduced.

Use the Henderson-Hasselbalch equation, eq. (3), to calculate the pH expected for a buffer solution prepared from this acid and
notka56 [123]

Answer:

pH=4.56

Explanation:

Hello there!

In this case, given the Henderson-Hasselbach equation, it is possible for us to compute the pH by firstly computing the concentration of the acid and the conjugate base; for this purpose we assume that the volume of the total solution is 0.025 L and the molar mass of the sodium base is 234 - 1 + 23 = 256 g/mol as one H is replaced by the Na:

n_{acid}=\frac{0.2g}{234g/mol}=0.000855mol\\\\n_{base}= \frac{0.2g}{256g/mol}=0.000781mol

And the concentrations are:

[acid]=0.000855mol/0.025L=0.0342M

[base]=0.000781mol/0.025L=0.0312M

Then, considering that the Ka of this acid is 2.5x10⁻⁵, we obtain for the pH:

pH=-log(2.5x10^{-5})+log(\frac{0.0312M}{0.0342M} )\\\\pH=4.60-0.04\\\\pH=4.56

Best regards!

algol [13]

The correct answer for this question is 'False'

Environmental science is not the study of the earth's natural hazards

What is Environmental science?

Environmental Science is the study of physical, chemical, biological components of earth's natural environment they include air, water etc.,

The Environmental science closely studies the human impact on the earth's environment.

This field of science also helps us to know about how science effects our environment.

And the 3 main aspects of Environmental science are:

To understand the interaction between humans and environment

To understand how natural world works

To Find a way to deal with the environmental problems to live sustainably.
