Answer:
The mechanism of this reaction i shown on the second uploaded image
The final product of the reaction is shown on the third uploaded image
The hydroxide would be first mixed with the ketone group before the aldehyde is added
Explanation:
The compound given in the question is 2,2-dimethylpropanal (pivalaldehyde) the structural formula is shown on the first uploaded image
looking at the structurally formula we can see that the hydroxide promoted reaction of this compound would be between the ketone and aldehyde functional group present in this compound in the presence of a hydroxide
Now this process of the reaction is this
The 
is first made to react with the ketone group
Then the aldehyde is added
What happens is that that the would search for an acidic proton because it is a base and this acidic proton is present in ketone and absent in aldehyde group hence the reason for the first reaction with the ketone group before the aldehyde is added
Economic concerns is the correct one
Heterogeneous mixtures are made of different substances that remain physically seperate. An example would be mixing sand and sugar together.
the answer would be soil
The answer is B soil
1. 5 electrons.
- Therefore, the 3d subshells blanks will be like this:

The correct option is this: EFFUSION BECAUSE THERE IS A MOVEMENT OF A GAS THROUGH A SMALL OPENING INTO A LARGER VOLUME.
Effusion refers to the movement of gas particles through a small hole. According to Graham's law, the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
