How many moles of carbon monoxide are needed to produce 48.0 L of hydrogen gas according to the following reaction at 0 C and 1 atm
carbon monoxide (g) + water (l) ------carbon dioxide (g) + hydrogen (g)
Acetylene,C2H2 , can be converted to ethane,C2H6 , by a process known as hydrogenation. The reaction is C2H2 + 2H2 --> C2H6 Given the following data, what is the value of K(p) for this reaction?
A sample of sodium reacts completely with 0.355 of chlorine, forming 585 of sodium chloride. What mass of sodium reacted?
An injection containing 10.0pg 10 5 B was injected into a patient suffering from a brain tumor. The patient was irradiated by a neutron gun at the site of the tumor.
If the sample contains a combined total of 1.50 mol and has a total mass of 45.0g, what are the percentages of CO2 and Ne in the sample by mole?
Caulculate the change in pH when 0.95 g of CH3COONa is added to 48 mL of 0.50 M acetic acid, CH3COOH. Ignore any changes in volume. The Ka for CH3COOH is 1.8 * 10^-5
A solution of 0.10 M sodium acetate is mixed with a solution of 0.10 M acetic acid (Ka = 1.8*10^-5). When equal volumes of the two solutions are mixed together the resulting mixed has a pH of:
portion of that solution is diluted by adding 165 mL of water. What is the final concentration? Assume the volumes are additive.
Battery acid is 35% sulfuric acid in water and has a density of 1.29g/ml. What is the mass of sulfuric acid in 1.00L of battery acid?
Tris is widely used in a biochemical laboratory. Its acid dissociation constant is 8.32 x 10^-9. You have available at your lab bench a 0.1 M solution of Tris in its protonated form, 0.1 M solution of HCL and NaOH,
A volume of 120 mL of H2O is initially at room temperature (22.0 C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.1 C , what is the mass of the steel bar?
The Ksp value for the dissociation of barium nitrate is 0.00464. The molar solubility of barium nitrate is consequently 0.105 M. If the concentration of the barium ion in a saturated solution of barium nitrate was raised to 0.178 M (this is not th..
