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.
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.
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
Answer:
B
Explanation:
follow the chart starting at the y axis go away from it at the level of 1 till you hit 100
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.
