Explanation:
boiling water has high temperature as it's molecules have high average KE ( kinetic energy) than ice....
Solubility of KMnO4 in water is 6.4 g/100mL Which means maximum of 6.4 g of KMnO4 can dissolve in 100 mL of water. ... And in given situation, 0.35 moles are added to 500 mL of water which is off the limit and thus it cannot be dissolved completely.
The atom that cannot serve as a central atom in a Lewis structure are the He, F, and H. That is option B, C and D respectively.
<h3>What is a Lewis structure?</h3>
The Lewis structure is defined as the structure in chemistry that is used to represent the Valence electrons of an atom in dot forms.
The atoms that can not serve as central atom in a Lewis structure are the He, F, and H atoms. This is so because:
- Helium (1s2) is a noble gas, and as such, it does not need to bond to any other atoms.
- Hydrogen (1s1) and fluorine (1s22s22p5) only need one electron to complete their valence shells.
