Answer:
i think its b
Explanation:
im sorry if its wrong i tried really hard
Because carbon has a molar mads of 12 (6 protons and 6 neutrons) while sulfur has a molar mass of 16 (8 protons and 8 neutrons)
Answer:
1. absorb water,get rid of of waste products
2.chewing
3. absorbing nutrients
4. holding the food, breakdown of food
So in order to answer this we need the number of moles of oxygen and the right stoichiometry.
The balanced reaction should be 2HgO --> 2Hg + O2, therefore 2 moles of mercury are produced for every one mole of oxygen gas. Since we have the mass of O2 we can calculate the moles as moles = mass/RMM where RMM is the relative molecular mass of O2, which is 32 g/mol. Therefore the number of moles = 125/16 = 3.9 mol.
Since 2 moles of Hg are produced for every one mole of O2, the number of moles of Hg = 3.9*2 = 7.8 mol.
