Prochirality is an important concept in biological chemistry because enzymes can distinguish between the two ‘identical’ groups bound to a prochiral carbon center due to the fact that they occupy different regions in three-dimensional space.
Second- Beryllium (Be)
Third- Magnesium (Mg)
Fourth- Calcium (Ca)
Fifth- Strontium (Sr)
1. 6.5*10^6
2. 5.94*10^-3
3. 1.2*10^2
4. 2.05*10^-2
5. 7.00*10^-1
Sorry if this is incorrect. To my understanding this is the correct answer.
Answer:
Aluminum Reacts With Hydrochloric Acid To Produce Aluminum Chloride And Hydrogen Gas. 2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)What Mass Of H2(g) Is Required From The Reaction Of 0.75 G Of Al(s) With Excess Hydrochloric
Answer: Nickel has one more proton.
Explanation:
The Periodic table orders elements based on their atomic number not by their atomic mass even though this order usually coincides with the atomic masses of the elements. Occasionally however, this is not the case as is proven by Cobalt and Nickel.
The atomic number of an element refers to the number of protons that the element has in its nucleus. Cobalt has 27 protons whilst Nickel has one more proton at 28 which is why it comes after Cobalt.
