Find the mass of the substance and the volume of a gas in a reaction.
1.Ammonium nitrate is a common ingredient in chemical fertilizers. Use the reaction shown to calculate the mass of solid ammonium nitrate that must be used to obtain 0.145 L of dinitrogen oxide gas at STP.
NH4NO3(s) N2O(g) + 2 H2O(g)
2. How many liters of propane gas (C3H8) will undergo complete combustion with 34.7 L of oxygen gas?
The 20 mL of water added to the Erlenmeyer flask is to be previously boiled, deionized water. Since water does absorb CO2 from the atmosphere and since CO2 dissolved in water causes it to be slightly acidic,
what is the wavelength ,in nanometers, of light with an energy content of 1979Kj/mol. In what portion of the electromagnetic spectrum in this light
How many molecular orbitals will be formed by combination of the 3s and 3p atomic orbitals in 1.0 mol of Mg atoms. At 0 K, what fraction of these orbitals will be occupied by electron pairs (all orbitals filled up to the Fermi level)
NaOH + CO2 -> Na2CO3 + H2O. If the average human body discharges 745 g of CO2 per day, how much NaOH is needed each day for each person in the spacecraft.
why would the chemiluminescence be more pronounced than with the flask stoppered? Why is the chemiluminescence even more pronounced with the ferricyanide/hydrogen peroxide mixture?
If 125 calories of heat is applied to a 60.0 grams piece of copper at 21.0 degrees Celsius, what will the final temperature be? The specific heat of copper is 0.0920 calories per grams times Celsius.
If the total pressure in the flasks is 311 torr after the stopcock is opened, determine the initial pressure of N2 in the 1.00 L flask.
The acceptable limit for mercury in drinking water is 2ppb. Does this correspoond to mercury in its elemental form (Hg) or in its ionic form (Hg^2)
Calculate the vapor pressure of water, in torr, above a solution prepared by dissolving 65.40 g of ZnCl2 in 445.0 g of water at 323.0 K. The vapor pressure of pure water at 323.0 K is 92.50 torr.
Cyclopropane is made up of 85.7% C and 14.3% H. What is the molecular formula of cyclopropane? And what is it chemical formula?
Plot the normalized particle in a box wavefunctions for an electron in a box of 1210 pm for n=1-6 on the same plot. Are any patterns evident? what is the probability of finding an electron in the middle 605 pm for n=6
