<u>Answer:</u> The ionic compound formed is magnesium chloride having formula
<u>Explanation:</u>
Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.
The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.
Magnesium is the 12th element of the periodic table having electronic configuration of
This element will loose 2 electrons to form ion
Chlorine is the 17th element of the periodic table having electronic configuration of
This element will gain 1 electron to form ion
So, for every 1 atom of magnesium, 2 atoms of chlorine are required. Thus, the chemical formula becomes
Hence, the ionic compound formed is magnesium chloride having formula
Answer: The percent composition of oxygen is 54.5%
Explanation:
Below I have attached my work through, but essentially the percent composition relies on finding the mass of the oxygens and dividing it by the mass of the whole compound. The masses of the elements can be found on the periodic table and added together to get a mass of the whole compound- ascorbic acid. Then, you turn this proportion into a percent by multiplying by 100%.
