You didn't post the whole question. However the answer would be : Mg, according to former questions in this website.
Hope this helps !

Answer:
1 mole of calcium, one mole of carbon, and 3 moles of oxygen.
Explanation:
The amount of the precipitate PbCl2 can be obtained using stoichiometry, assuming the reaction goes into completion given the excess amounts of the lead (II) nitrate solution. First, divide 2.5 g NaCl to its MW of 58.44 g/ mol to obtain the moles of NaCl involved in the reaction. Second, knowing that for every 2 moles of NaCl, there is 1 mole of PbCl2 produced, we divide the moles of NaCl obtained earlier by 2 to get the moles of PbCl2 produced. From the moles of PbCl2, we multiply it to its MW of 278.1 g/ mol. The amount of precipitate is then calculated to be 5.9484 g PbCl2.
C6H12O6, also known as glucose, is a carbohydrate. Another name of the carbohydrate is a monosachharide, and it is produced by plants while conducting photosynthesis.
