Always use significant figure rules. Remember that these rules apply to all numbers that are measurements. A series circuit contains both a 6Ω and a 3Ω resistor. Through the 6Ω resistor, the current is 0.5 amps. What will the current be through the 3Ω resistor? 0.5 amps 0.25 amps 3.0 amps 1.0 amps

Answer ozone (o3) is made of three atoms of oxygen, it is a molecule;

Oxygen= 88ghydrogen= 12g

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 -
