They contain the same number of molecules; however, the masses can differ depending on the molar masses of the substances.
Answer:
K20(s)+H2O(L) -> 2KOH(aq)
Answer:
Option (3)
Explanation:
Ductility of a substance is defined as the property by which a substance can be hammered and change its form into thin, stretched wires. In simple words, the ductile materials can be drawn into thin wires. Some of the examples of ductile substances are gold, copper and silver.
The rocks also have this property which means that they have the capacity to get deformed into enormous strains in the absence of large scale fracturing.
Thus, the correct answer is an option (3).
Answer:
D. The lone pair forces bonding atoms away from itself.
Explanation:
The lone pairs are found in the outermost shell thereby making sharing of electrons easier. Lone pairs which are found in a covalent bond creates a bond angle which makes it a determinant of the bond angle.
The lone pairs which are negatively charged repulses the bond pairs thereby creating a distortion in the shape of the molecule.
The lone pairs creates the distortion by forcing bonding atoms away from itself.
