I need help on this second one please
2) How many moles of sodium will react with water to produce 4.0mol of hydrogen in the following reaction? 2Na + 2H,0 a 2N2OH + H, Propane (C,H,) is commonly used in gas grills. a) If 3.2 L of carbon dioxide are formed at STP in the combustion of propane, how many moles of propane were burned? (STP-standard temperature and pressure or 25°C and latm) b) If 32grams of water are produced during the combustion of propane, how many moles of propane were burned? 3) Phosphorous burns in air to produce a phosphorous oxide in the following reaction: 4P + 50, à P̟o,0 a) What mass of phosphorous will be needed to produce 3.25mol of P O ? b) If 0.489mol of phosphorous burns, what mass of oxygen is used? 4) Aluminum chips are sometimes added to sodium hydroxide-based drain cleaners because they react to generate hydrogen gas which bubbles and helps loosen material in the drain. The equation follows Al + NAOH + H,O a NAAIO, + H,
