Prophase is the first step in mitosis!
That's a ionic compound because it has a metal and polyatomic parts within the chemical formula.
It seems to have choices. You can get the electronegativity order from the periodic table of elements. From left to right, the electronegativity will also increase. From top to bottom, it will decrease.
Empirical Formula for given compound Ba1C2N2.
<u>Explanation</u>:
<u>Step 1; </u>convert the mass of each element into their molar values by dividing available mass by molar masses.
Molar masses of required elements are as follows; Ba- 137.327, C- 12, N- 14.
<u>Step 2;</u> Divide all the values by the smallest mole value. For given compound after dividing the masses by molar masses we get 0.0690, 0.1383, 0.1378 for elements Ba, C, N respectively. Divide all three values with the least value which is 0.0690 and note these values.
<u>Step 3;</u> Convert all the numbers available into whole numbers by multiplying with suitable values. i.e. 3 if values are 0.33, 2 if values are 0.5 etc.
<u>Step 4;</u> Assign these values to corresponding elements and you will get the above empirical formula.
Group 16 must gain 2 electrons to become stable :)
Hope this helps!!
