Tungsten carbide is becoming popular for making jewelry. a chemist is examining a sample of tungsten carbide (chemical formula wc). what is the percent composition of tungsten in this compound? round your answer to the nearest whole percent. the percent composition of tungsten is %

The percent composition of W in WC is 93.868 %.

MM of WC = 183.84 u + 12.01 u = 195.85 u

% W = Mass of W/Mass of WC × 100 % = 183.84 u/195.85 u × 100 %

= 93.868 %.

% composition of tungsten ( W) = 93.86%

solution is attached below

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
