4 NH3 + 5 O 2 -----> 4 NO + 6 H2O  HOW MANY MOLES OF OXYGEN (O2) ARE NEEDED TO REACT WITH 51.12 GRAMS OF AMMONIA(NH3) BY THIS REACTION ? NH3 MOLAR MASS = 17.04g/mol 2 C4H10+13 O2 --------------> 8 CO2+ 10H2O HOW MANY GRAMS OF WATER (H2O) ARE PRODUCED IF 100.0 MOLES OF C4H10 ARE USED? H2O MOLAR MASS = 18.02 G /MOL

4. An old antacid commercial claimed that each tablet of their product could "neutralize 47 times its mass in stomach acid". The active ingredient in the antiacid tablet, NaAl(OH)₂CO3, reacts with HCl in stomach acid according to this balanced reaction: NaAl(OH)₂CO3 + 4 HCl →→ NaCl + AlCl³ + 3 H₂O + CO₂ How many moles of HCl can a 1.03 g of antiacid tablet neutralize if the tablet contains 0.246 g of the active ingredient? If stomach acid has a concentration of 0.14 M HCl, assuming the density of stomach acid to be similar to that of water (1.00 g/mL), what is the mass of stomach acid that the 1.03 g of antiacid tablet can neutralize? Does this number support the claim in the commercial?

Baking soda is a pure substance, sodium bicarbonate. Vinegar is a mixture of acetic acid dissolved in water, and it is only the acetic acid that reacts. Acetic acid and sodium bicarbonate can react together according to the chemical equation below: HC2H302 NaHCOe NAC2H302 + H20 + CO2 acetic acid + sodium bicarbonate sodium acetate + water + carbon dioxide Samuel wants to help his brother make a science fair volcano. 1. For his first experiment, Samuel obtains samples of solid acetic acid powder and solid sodium bicarbonate powder from his chemistry teacher. He mixes the two powders together, but there is no reaction. b) Considering the state of matter of the particles, give a possible explanation for why there is no reaction.
