For each of the reactions, calculate the mass (in grams) of the product formed when 3.51g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant.
__Ba(s) + Cl2(g) = BaCl2(s)__CaO(s) + CO2(g) = CaCO3(s)__2Mg(s) + O2(g) = 2MgO2(s)__4Al(s) + 3O2(g) = 2Al2O3(s)
The atmospheric activity of 14 C is 15 cpm/gC (counts per minute per gram of carbon). Assume that the cloth was made in the year 24 B.C. The half-life of 14 C is 5730 years. What will be the expected activity of 14 C of this sample
The reactions represented below are all spoontaneous as written. For each, write the anode and cathode half - reactions and indicate the signs of the electrodes.
explain why covalent bonds are formed when non metals from the right side of the periodic table bond with each other. Give two examples of such compounds.
Ammonium Carbonate, NH4CO2, decomposes as follows: NH4CO2NH2(s) -> 2NH3(g) + CO2(g) Starting with only the solid, it is found that at 40C the total gas pressure is .363 atm. Calculate Kp.
A mass of 1.50 g H2O is sealed in an evacuated 3.0-L flask and heated to 55 °C. What mass of liquid water remains in the flask when equilibrium is established? The equilibrium vapor pressure of water at 55 °C is 118 mm Hg.
In a 1.0× 10-2 M solution of NH4ClO4(aq), identify the relative molar amounts of these species from Most to Least.
