In the process of underwater welding, a gas bubble is intentionally formed around the weld to protect it from water until it has cooled. To do so, a mixture of gas is used containing mole fractions of χH2=0.70 (70% hydrogen), χCO2=0.25 (25% carbon dioxide), and χCO=0.05 (5% carbon monoxide). If the total pressure on this gas bubble is 2.6 atm, what are the partial pressures of the three component gases (in atm)?

Which of these properties, used alone, would be least useful in identifying most minerals? a. color b. luster c. streak d. density

What approach is required to balance the objectives of sustainable development? balancing the objectives of sustainable development requires a(n) .

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
