Determine the mole ratios using balanced equation: C3H8(g)+ 5O2(g) --> 3CO2(g)+ 4H2O(g) 1. C3H8:O2 __?__
2. C3H8:CO2 __?__
3. O2:H2O __?__
4. CO2:O2 __?__

5. How many grams of water are produced when 12.00 moles of C3H8 react?

6. How many moles of oxygen gas are necessary to produce 35.0 grams of water?

7. How many grams of carbon dioxide are produced when 100.00 g of C3H8 react?

Nonmetals usually react by gaining electrons

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
