p4s f2g -gt pf3g what mass of f2 is needed to produce 187 g of pf3 if the reaction has a 80.1
If the specific heat of the ball bearing is .474 J/g times degress C, calculate the final temperature of the water. Assume the calorimeter to have neglible heat capacity.
If the water initially has a temperature of 26 0C, how many kilojoules of heat must be removed to cool and freeze the water at 0 0C?
When two gases are mixed, they follow Dalton's law of partial pressures. -It is impossible to compress a gas enough so that it takes up no volume. -CO2 gas becomes dry ice (solid CO2) at 1 atm and -78.5 °C.
Calculate the [SCN-] solution A, where 5.7 mL of 2.910?3 M NaSCN is diluted to 44.0 mL with 0.1 M Fe(NO3)3. Next calculate the [FeSCN2+] in the solutions prepared by diluting volumes of solution A with 0.1 M Fe(NO3)3 to a final volume of 1.0101 mL..
Calculate the heat removal rate (kW) needed to produce 500 kg/h of dry ice at -78.4°C from a feed stream of CO2 (v) at 20°C.
a) write a balanced equation for the reation. b) When 46.0 g of KClO3 is heated, 12.1 g of O2 is formed. How many grams of KCl is also formed? c) What is the percent yield of O2 for the reaction
Using graphical techniques, calculate the distribution (i.e., the fraction) of chlorendic acid ( in uncharged, mono-anionic and di-anionic forms) at pH 3.5,5.0, and 7.5.
The balences in the lab can weigh a maximum of 220.000 g at once. if a beaker has a mass of 86.4329 g, what is the maximum volum of water
An ideal gas flows through a horizontal tube at steady state. no heat is added and no shaft work is done.the cross sectional area of the tube changes with length and this causes the velocity to change
One liter of O2, one liter of N2, and one liter of H2 are collected at a pressure of three atmospheres, each in a different container. The three gases are then forced into a single vessel of one-liter capacity,
Draw an energy-reaction coordinate diagram for both exothermic and endothermic reactions and compare the two. How would temperature changes observed using a calorimeter differ for exothermic and endothermic reactions?
