Some people weren't convinced with the theory. Also many people tried to prove that the atom didn't exist, or at least prove the theory wrong.
People had asked this many times and that is why they came up with methods and standards that will answer these type of questions. You can look it up in the NIST or the National Institute for Standards and Technology.
Answer:
Following DNA replication, the chromosome consists of two identical structures called (sister chromatids), which are joined at the centromere.
Answer:
The coordination number is 4.
Explanation:
- Square planar clusters can be either cis or trans, as they form 180 and 90-degree bond angles. Therefore, a pair of ions may be adjacent (cis) to one another and immediately across (trans) from one another.
- A square planar molecule could never be simultaneously cis and trans, so because several coordinators are 4.
- Since linear complexes have only an angle of a bond of 180 degrees, they can not have cis or trans-isomers. In the coordination complex, there is only yet another way possible of bonding the two binding sites to the steel.
The formula here is:
pH = -log[H+]
3.6 = -log[H+]
[H+] = 2.51 x 10⁻⁴ mol / Liter
The first option is correct.
