If most objects are made up of free space then why can we put our hands through a book or wall?
Mazyrski [523]
I suppose you mean to ask why we can't go through obstacles.

Any atom is surrounded by an electronic cloud. When two atoms get close to each other, the electronic clouds repel each other, preventing them from interpenetrating each other. That same phenomenon, on a larger scale, prevents us from going through matter.

Which set of reagents will best convert 2,2-dimethylpropan-1-ol (neopentyl alcohol) to 4,4-dimethylpentan-2-ol
Sladkaya [172]

Answer:

SOCl2, Mg, CH3CHO, H3O^+

Explanation:

The reaction of the 2,2-dimethylpropan-1-ol  with SOCl2 converts the alcohol to an alkyl halide. This now reacts with Mg metal to yield a Grignard reagent.

The Grignard reagent reacts with CH3CHO and acid  to yield  4,4-dimethylpentan-2-ol as shown in the image attached to this answer.

What is the pH of 0.12M HNO3
Phoenix [80]

Answer:

pH= 0.92

Explanation:

HNO3-> H^+ +NO3^-

HNO3 is a strong acid, so it fully dissociates

[HNO3] = 0.12M    [H^+] = 0.12M  

pH= -log[H^+]

pH=-log[.12] = 0.92

pH = 0.92

Why is water displacement an effective way of measuring the volume of an irregular solid?
icang [17]

Answer:

There is no way of finding the volume of an irregular shape.

We cant find the volume of an irregular solid because we can never measure the volume of curves that are present in an irregularly shaped object. so we tend to place this irregular object in a beaker of water so that the volume of water displaced by it will actually show us the volume of object itself. And now we can conclude that water displacement is an effective way of measuring the volume of an irregular solid there is no way of finding the volume of an irregular shape.
