The compounds are missing. It will be helpful instead if you know what are stereoisomers. <span>Two molecules are described as stereoisomers of each other if they are made of the same </span>atoms<span>, connected in the same sequence, but the atoms are positioned differently in space in which the difference between two stereoisomers can only be seen when the three dimensional arrangement of the molecules is shown.</span>
Answer: GeH4 (Germanium(IV) Hydride)
Explanation:
A Binary molecular compound Hydrogen and a Group 4A element which is more more acidic than SiH4 in aqueous solution is GeH4.
The pKa of GeH4;
= 25
Whilst that of SiH4
= 35
The lesser the pKa the higher the Ka which means more acidic.
A. An oxidation state is a number that is assigned to an element in a chemical combination. This number represents the number of electrons that an atom can gain, lose, or share when chemically bonding with an atom of another element.
1. <span>The region in which an electron is most likely to be found is called an orbital.
2. </span>An atom in which an electron has moved to a higher energy level is in an excited state.
3. When Mendeleev organized elements in his periodic table in order of increasing mass, elements with similar properties were in the same column.
4. Mendeleev’s periodic table was useful because it enabled scientists to predict properties of unknown elements.
As you move from left to right of the periodic table, the element becomes more negative.
