Why nitromethane (ch3No2) have one double bond on oxgen... why not both oxygen have a double bond when writing the resonanace forms?
What is the percent yield of ammonia when 150.0 g of nitrogen reacts with 32.1 g of hydrogen if the actual yield is 174 grams?
write a balanced equation for the photosynthesis reaction in which gaseous carbon dioxide and liquid water react in the
The equilibrium system H2 + I2 ? 2HI has equilibrium constant K = 6.2. Starting from the nonequilibrium state [H2] = 0.3 M, [I2] = 0.5 M, and [HI] = 0.7 M, what are the concentrations of the three molecules when equilibrium is established
Calculate the experimental value for Ksp for KHP and determine whether it is within 10% of the theoretical Ksp value (solubility = 8.0g/L). If not, give one reason why this error might have occurred.
Suppose that 5193.0 J of heat energy is added to 7 g of ice initially at -10 C. (This could be done, for example, by electrical heating of ice in an insulated container.) What is the final temperature of the water
detailed procedure of determining the enthalpy of reaction between citric acid (H3Cit) and sodium hydroxide (NaOH). Calculate what volume of each .50M solution should be mixed to give a total volume of 50.0mL and the reactants in the correct stoic..
Write balanced molecular equations, complete ionic equations, and net ionic equations for the following reactions. Write "NR" if there is no reaction. All reactants are aqueous solutions.
How long would it take for 1.50 mol of water at 100.0 degrees Celsius to be converted completely into steam if heat were added at a constant rate of 15.0 J/s.
What is the purpose of the sodium bisulfite? If bisulfite is oxidized to sulfate
When the sample burned, the products were CO2 gas and H2O vapor. The CO2 was collected and its pressure found to be 25.2kPa in the same volume and at the same temperature as the original mixture. What % of original mixture was methane
when formic acid is heated it decomposes to hydrogen and carbon dioxide in a first order decay calculate the partial
