Liquid water and nitrogen monoxide gas are produced from the reaction of 22.7 grams of ammonia gas with 53 grams of oxygen gas. 36.0 grams of water were measured at the end of the reaction. What mass of nitrogen monoxide gas was produced from the reaction?
Every measurement has a measurement uncertainty. Discuss how precise and accurate measurement can be achieved in spite of the inherent measurement uncertainty.
It has a diameter of 13.46 cm. On the other hand, spent uranium (from processing which removes the commercially important rare isotope) has a specific gravity of 19.05. How many pounds would a uranium cannonball of the same dimensions as the iron ..

What volume of H2 (at 25oC and 1.00 atm ) can be produced by reaction of 161 g Fe and 202 g of HCl? (Atomic weights: Fe = 55.85, Cl = 35.45, H = 1.008).
if 150 ml of 1.50 m perchloric acid hclo4 is combined with 500 ml of 0.125 m barium hydroxidebaoh2 then compute the
How many grams of NaH2PO4 are needed to react with 43.74 mL of 0.285 M NaOH by the following reaction- NaH2PO4(s) + 2 NaOH(aq) --> Na3PO4(aq) + 2 H2O(l)
The difference between the energy of the photons and the kinetic energy of the electrons corresponds to the energy needed to remove the electrons (that is, the ionization energy). Suppose that a PES experiment is performed in which mercury vapor i..
The heat of vaporization of liquid nitrogen is determined by measuring the change in temperature of a known sample of warm water when liquid nitrogen is added.
Write the balanced equation for the ionization of the weak base pyridine, C5H5N, in water, H2O. Phases, such as (aq) or (l), are optional.
