When the following molecular equation is balanced using the smallest possible Integer coefficients, the values of these coefficients are: Na (s) + H₂0 (1) NaOH(aq) + H₂ (g) 2/ - T E✓ ✓ ✓ A6 0 Submit Answer When the following molecular equation is balanced using the smallest possible Integer coefficients, the values of these coeff Do Br₂(g) + Cl₂(g) → BrCl(g)

Balance the following equation - If a coefficient is a one (1) PUT IT IN even though that would be optional if you were writing the equation yourself.

The lead-acid storage battery is the oldest rechargeable battery in existence. It was invented in 1859 by French physician Gaston Plante and still retains application today, more than 150 years later. There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid decomposes to form sulfur trioxide and water: H₂SO4(1)→ SO3(g) + H₂O(1) AH +113. kJ In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate: Pb(s) + PbO₂(s) + 2SO3(g) 2 PbSO4(s) Calculate the net change in enthalpy for the formation of one mole of lead (II) sulfate from lead, lead(IV) oxide, and sulfuric acid from these reactions. Round your answer to the nearest kJ. kJ AH = -775. kJ X

"Smelling salts," which are used to revive someone who has fainted, typically contain ammonium carbonate, (NH4)2CO3 . Ammonium carbonate decomposes readily to form ammonia, carbon dioxide, and water. The strong odor of ammonia usually restores consciousness in the person who has tainted. The unbalanced equation is: ( NH4 )2 CO3( s)→ NH3(g ) + CO2( g) + H2O(g ) calculate the mass of ammonia gas that is produced if 1.25 g of ammonium carbonate decomposes completely.
