This dissociation occur because:
O had to bond with H due to the Hydrogen bonding rule, which will form OH~ (Hydroxide).
K is more attracted to Hydroxide than Cl, so it will depart Cl and bond with OH~.
that leaves a H and a Cl, which one has a positive charge and the other has a negative, so they will bond and form Hydrochloric Acid.
Answer:
Explanation:
Hello,
In this case, considering that the compound is 48% oxygen, we infer it is 52% chromium, therefore, by using their atomic masses we compute the moles by assuming those percentages as masses:
Next, by dividing by the smallest moles, we find the subscripts in the empirical formula:
Which are also expressed in the smallest whole numbers, therefore the empirical formula is:
Which corresponds to the chromic oxide or chromium (IV) oxide.
Regards.
