if equal masses of N2 and H2 (7.00 grams each) are combined to produce ammonia NH3, how many grams of ammonia could be produced at maximum yield?
N2 + 3 H2 ---> 2 NH3
when 15.0g of steam drops in temperture from 275.0C to 250.0C how much heat is released csteam=2.01j/gC
The specific heats of ice and water are 2.09 and 4.184 J/g.°C, respectively. The heat of fusion for water is 334 J/g.
how many grams of metallic copper can be obtained when 54.0 grams of Aluminum react wit 319 grams of CuSO4?
Heat is lost to the styrofoam calorimeter. Assuming a 6.22 C temperature change for the reaction of HCl(aq) with NaOH(aq), calculate the heat loss to the inner 2.35-g styrofoam cup. The specific heat of styrofoam is 1.34 J/gC.
If 69.5 kJ of heat is applied to a 1032 g block of metal, the temperature of the metal increases by 11.4°C. Calculate the specific heat capacity of the metal in J/g°C.
A helium-filled balloon at sea level has a volume of 2.5 L at 0.989 atm and 33°C. If it is released and rises to an elevation at which the pressure is 0.900 atm and the temperature is 29°C, what will be the new volume of the balloon?
A 100.0 mL of acetic acid solution of unknown molarity is titrated with 0.15 M NaOH solution. The titration requires 43.25 mL of the base. Determine the molarity of the acid, CH3COOH.
A beaker with 120 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 5.50 mL of a 0.250 M HCl solution to the beaker. How much will the pH..
