Explanation:
As we known that an ionic solid is a solid whose atoms chemically combine together by transfer of electrons from one atom to another.
For example, is an ionic solid because transfer of electrons take place from calcium to chlorine.
As a result, calcium atom has a partial positive change and chlorine atom has a partial negative charge. Hence, there will be strong intermolecular forces of attraction between the two because opposite charges attract each other.
Therefore, particles will be arranged in a regular crystal lattice of opposite charges.
Answer:
Explanation:
Since it first order, we use order rate equation
In ( ) = -kt where A1 is the final quality = 0.8 (80%), A0 is the initial quality = 1 ( 100%)
also, t half life = where k is rate constant
k = = 0.0154
In ( ) = - 0.0154 t
-0.223 / -0.0154 = t
t = 14.49 approx 14.5 days from the date the yogurt was packaged
