e) hydrogen gas is passed over hot iron (II) oxide powder. Samples of boron trichloride gas and ammonia gas are mixed. d) phosphine (phosphorus trihydride) gas is bubbled into liquid boron trichloride. (e) Hydrogen gas is passed over hot iron(II) oxide powder. (d) Phosphine (phosphorus trihydride) gas is bubbled into liquid boron trichloride. Calcium metal is heated strongly in nitrogen gas. 6. Fluid Phase Equilibria 2007, 253 (2) , 98-107. (f) Solid potassium amide is added to distilled water. (f) Sulfur trioxide gas is bubbled into water. (d) A solution of lead(II) nitrate is added to a solution of potassium sulfate. (e) Ammonia gas is mixed with hydrogen chloride gas. (f) Solid potassium amide is added to distilled water. 11. c) sulfur dioxide gas is bubbled into distilled water. (c) Sulfur dioxide gas is bubbled into distilled water. • Copper reacts with concentrated sulfuric acid to produce copper(II) sulfate, sulfur dioxide, and water. Carbon dioxide gas is bubbled into magnesium oxide. • Chlorine gas reacts with dilute sodium hydroxide to produce sodium hypochlorite, sodium chloride and water. The formula for carbonic acid is H2CO3 (aq). 10. A solution of pH 6 is produced. f) solid potassium amide is added to distilled water. g) a strip of magnesium metal is heated strongly in pure nitrogen gas. (g) A strip of magnesium metal is heated strongly in pure nitrogen gas. (g) A strip of magnesium metal is heated strongly in pure nitrogen gas. 9. If you put the two together, the sulfur will float on the surface of the water or at best, the sulfur will get wet. (b) Solid sodium hydride id added to water. (d) Phosphine (phosphorus trihydride) gas is bubbled into liquid boron trichloride. When carbon dioxide is bubbled through water, some of that carbon dioxide dissolves into the water. 5. (e) Hydrogen gas is passed over hot iron(II) oxide powder. SO2 (aq) + H2O (l) > >> H2SO3 (aq) • A metal sulfide reacts with oxygen to produce the metallic oxide and sulfur dioxide. sulfur dioxide gas is bubbled through water: SO₂ + H₂O → H₂SO₃ nonmetallic oxide: 362400820: solid tetraphosphorus decaoxide is dropped into a beaker of water: P₄O₁₀ + 6 H₂O → 4 H₃PO₄ nonmetallic oxide: 362400821: carbon dioxide gas is pumped into water: CO₂ + H₂O → H₂CO₃ nonmetallic oxide: 362400822 Excess chlorine gas is passed over hot iron filings. 8. Some carbon dioxide is bubbled into distilled water containing universal indicator. (c) Sulfur dioxide gas is bubbled into distilled water. Drops of dinitrogen trioxide are added to distilled water. Experimental determination of dissociation constant, Henry's constant, heat of reactions, SO2 absorbed and gas bubble–liquid interfacial area for dilute sulphur dioxide absorption into water. (c) Propoanone is burned in air. 7. Carbonated water is water that has been infused with carbon dioxide gas under pressure.. Sulphur dioxide can dissolve in water to form Sulfurous acid(H2SO3). It then can react with the water to form carbonic acid. (a) Hot hydrogen gas is passed over heated copper(II) oxide solid. The gases boron trifluoride and ammonia are mixed. Sulfur does not react with water. Sulfur 16 35.5 Cl Chlorine 17 40 Ar Argon 18 ... 6 Carbon dioxide gas forms when dilute nitric acid is added to marble chips.
