6. How many grams of NaOH (molar mass = 39.997 g/mol) are contained in 5.0 x 102 mL of a 0.81 M sodium hydroxide solution?

H2so4(aq) + mg(s)—> mgso4(aq) +h2(g) which substance is the acid in the reaction?

If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
