The first-order decomposition of phosphene to phosphorus and hydrogen 4PH3(g) → P4(g) + 6H2(g) has a half-life of 35.0 s at 680°C. Starting with 520 mmHg of pure phosphene in an 8.00-L flask at 680°, how long will it take for the total pressure in the flask to rise to 1.000 atm?
A 27.0-g sample of water at 250. K is mixed with 47.0 g water at 310. K. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
