Predict the products of each of these reactions and write balanced molecular equations for each. If no reaction occurs, write NOREACTION.
Cr(NO3)3(aq) + Na3PO4(aq)--->
liquid butanol (C4H10O) and gaseous oxygen
aqueous strontium sulfide and aqueous potassium sulfate
Technetium-99 is a long-live radioactive isotope of technetium. Each nucleus decays by emitting one beta particle. What is the product nucleus?
Methyl nitrite, CH3NO2, a gas at room temperature, is reacted with phenol, C6H6O, to give nitrophenol, in a reaction shown below.
Explain what happens to the atomic number of a nucleus when positron emission occurs
The thermocouple is then placed in boiling toluene at the same pressure and provides an output of 12.59 mA.
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
The energy levels the electron can occupy in the Be3+ ion can be calculated using the energy level equation. Calculate the energy in J of the electron when it is in the n= 4.00 level.
Calculate the volume of concentrated HCL (37% by weight, density 1.19 g/mL) that must be added to 500 mL of .10 M ammonia to make
Explain why a determination of the rate law can never prove a proposed reaction mechanism but can sometimes disprove
yellow-gold is an alloy that is 75.00% gold,16.00% silver and 9.00% copper (by mass). calculate the cost of the gold in a cube of the alloy 1.00 ft on a side.
To identify a diatomic gas (X2), a researcher carried out the following experiement. She weighed an empty 4.2L bulb, then filled it with the gas at 1.30atm and 23.0C and weighted it again. The difference in mass was 6.3 g. Identify the gas
