<span>According to naming rules, the types of compound that use prefixes in their names are the covalent compounds. These are formed by sharing of valence electrons, by the atoms, and results in the formation of a covalent bond. For example, water and DNA.</span>
Answer: 2 : 1
Explanation:
Cation :
Ca - calcium = atomic number = 20
Electron dot configuration : 2, 8, 8, 2
Ca losses 2 electrons in its outermost shell and thus has a charge of 2+ in other to attain a stable octet state.
Anion:
F - has 7 valence electrons and thus needs 1 electron to achieve a stable octet state, hence it accepts one electron has has a charge of (-1)
Therefore,
Ratio of cation (+) to negative (-) = 2 :1
Answer:
Explanation:
Hello!
In this case, since the percent recovery for this crystallization operation is computed as shown below:
Thus, by plugging in the initial 8.95 g and the recovered 7.20 g, we obtain:
