reactant concentration
Answer:
Explanation:
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.

Answer:
C
Explanation:
Pressure it says it in the name its the force of colliding particles
Answer:
Option C is correct.
The atoms sharing the electron pairs will spread out around the central atom.
Explanation:
In covalent bonding, the atoms involved form a bond by sharing a pair of electrons. These pairs of electrons are repulsive towards one another, when they occur together around a central atom.
Infact, the Valence shell electron pair repulsion (VSEPR) theory explains further that 'electron pairs around a central atom arrange themselves so that they can be as far apart as possible from each other'.
So, it becomes obvious that the atoms that share these electron pairs around a central atom are pushed to spread out as far as possible around that central atom.
Hope this Helps!!!
