A sample of helium gas has a volume of 5.10L at a pressure of 815 mmHg and a temperature of 28C . 1. What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 1520mL and 347K if the amount of gas is constant?
2. What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 2.24L and 18°C if the amount of gas is constant?
3. What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 12.8L and 48°C if the amount of gas is constant?

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
