Question

reactants based on electronegativity values and balance the 112 pts) Predict products of the chemical reactants based on electronegativity values expected chemical equations List at least one specific reason for your choice as the cation anion in each case. a Gallium metal reacts with oxygen gas. b. Hypothetically, fluorine gas directly reacts with oxygen gas. 3. pls Molarity definitions and applications. Be sure to print a balanced chemical equation for scenario. (10 pts) Calculate the final molarity of stomach gastric juice, if a 4.2 L stomach holding about 3.0 liters of digestive fluid that is 0.0150 M hydrochloric acid at 298 K. is diluted with 1200 cc of water. b. (10 pts) Calculate the original molarity of the titrant, aqueous solid hydroxide. 20.0 mL of 0.500 M sulfuric acid (H2304(ag)) completely reacts with 25.0 mL of sodium hydroxide: Three drops of 1% phenolphthalein (in 95% ethanol) is the organic dye indicator used.
