Design an experiment using sequential qualitative analysis to determine whether a solution contains acetate or carbonate ions. For each stage of the test write net ionic equations that could occur. Identify how precipitation reactions can be used in the water treatment and purification processes to help maintain a safe municipal water supply.
what is the total pressure in the reaction flask at the end of the reaction? What are the partial pressures of the gases in the flask? 6A(g) + 2B(g) %u2192 2A3B(g)
Write the equation for the general form of an indicator equilibrium. Underline the form of the indicator in acidic solution, and circle the form of the indicator that is in largest concentration in basic solution
The effective nuclear charge is approximated as the total nuclear charge minus the number of core electrons. Thus, effectively, core electrons decrease the nuclear charge felt by the valence electrons because they are between the nucleus and the v..
Write the complete ionic equation for each reaction that produced a precipitate? Write the net ionic equation for each reaction that produced a precipitate?
approximately what percentage of the acetic acid molecules are protonated and neutral in charge at pH 5.7?
In an experiment, 0.30 mol H2 and 0.30 mol I2 are mixed into a 1.00-l container, and the reaction forms HI. If Kc =49 . for this reaction, what is the equalibrium concentration of HI. I2(g) + H2(g) 2HI(g)
How many milliliters of O2 gas at 25 C and 1.00 atm pressure are obtained by the thermal decomposition of 0.470g of KMnO4? The balanced equation for the reaction is:
Using the thermochemical data given for NO2 and N2O4 in class, determine the fraction of N2O4 that will dissociate into two NO2 molecules if one mole of pure N2O4 is introduced to a 10 liter constant volume,
a balloon of co2 g has a volume of 17.1 litres and contains 8.3 moles of co2. some carbon dioxide escapes due to a leak
the air is at a standard temperature and pressure, how many gaseous molucules does the flas contain
When an ant bites you, the reason it stings is because of an injection of formic acid. What is the pH when 50.0 mL of 0.1480 M formic acid (HCOOH) is titrated with 40.2 mL of 0.1841 M NaOH? PKa formic acid = 3.745.
THE IONIZATION ENERGY OF HYDROGEN. In a normal hydrogen atom, the electron is in the lowest energy state. The maximum energy that a hydrogen atom can have is 0 cm-1
