Nitrogen and hydrogen react together to form ammonia according to the equation:___N2(g) + ___H2(g) → ___NH3(g) (unbalanced)Balance the equation, and determine how many grams of hydrogen would be required to form 25.0 g of ammonia, assuming there is sufficient nitrogen available.
Consider the following reaction: HC2H3O2 (aq) + H2O (l) = H3O+ (aq) + C2H3O2- (aq) Kc=1.8*10^-5 at 25C If a solution initially contains 0.260M HC2H3O2, what is the equilibrium concentration of H3O+ at 25C
Look up the molar mass and the density of 2-chloro-2-methylpropane in a reference book such as The Merck Index. Calculate the number of moles of HCl that are produced by complete hydrolysis of 1.0 mL of 2-chloro-2-methylpropane.
Q 3: The salt NaBrO(3) oxides Sn^2+ to SnCl(6)^2- in the presence of hydrochloric acid according to the equation
The barometric pressure was 768.6 mmHg when the open end manometer attached to a flask holding a gas read 13.0 mmHg. (mercury level highest on the side connected to the flask.) what is the pressure of the gas in the flask in kilopascals?1.00 atm =..
The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 15.0 L. How many moles of gas (n_2) remain in the cylinder
The final volume of the balloon is 1500 mL. The atmospheric pressure is 1.00 atm. What was the original pressure of HI in the cylinder before the release of HI
nitroglycerin C3H5(NO3)3 detonates into N2, O2, CO2, and H2O. In addition 6.26 kJ of heat is given off per gram of nitroglycerine denotated. what is the specific heat when 4.65 g of N2 is formed
According to VSEPR theory, if there are five electron domains in the valence shell of an atom, what will be the expected electron domain geometry.
Explain, perhaps with the use of drawings, why the 0.2 mL correction for the use of an inverted cylinder is subtracted from (not added to) the measured volume readings.
Calculate the pH for 5 x 10-10 M HClO4. Please show work. The answer should come out to pH7 when auto-ionization of water is factored
50.00 mL of 0.10 M HNO2 (nitrous acid, Ka = 4.5 ´ 10-4) is titrated with a 0.10 M KOH solution. After 25.00 mL of the KOH solution is added, the pH in the titration flask will be
