Explanation:
Aquifers are porous and permeable formations that stores ground water. The ground water system is made up of mostly fresh water.
- An aquifer acts as a reserve for ground water in the environment.
- By passing through different formations, water that recharges them are purified.
- This makes them fresh and mostly free from salt intrusion
An aquifer is able to store this fresh water and it is is good prospect for sourcing ground water.
Answer:
C) They are not made of matter.
Explanation:
Case in which protons are inside of neutrons doesn't exist.
It would be 65 miles per hour
B is a double replacement reaction where OH and Br switch places.
Structures of <span>
1-bromo-3-methyl-2-butene and </span>
2-bromo-3-methyl-2-butene are shown below.
It can be seen that <span>
1-bromo-3-methyl-2-butene is containing a C-H bond in which carbon is sp</span>² hybridized (i.e. =C-H) while such bonding is absent in
2-bromo-3-methyl-2-butene.
So, as we know that the peak of C-H stretching of alkenes is found in the region of 3010-3100 cm⁻¹ with medium intensity. Therefore,
1-bromo-3-methyl-2-butene will show this peak and
2-bromo-3-methyl-2-butene will lack this peak in IR spectrum.
