If you are given a 0.33 g piece of sodium metal to react with water, how many moles of HCl would it take to neutralize the sodium hydroxide produced?
Balancing equation to calculate correct number of moles If CaC2 + 2 H2O --> C2H2 + Ca(OH)2 then, there are 65 grams of calcium carbide
An antacid tablet containing calcium carbonate as an active ingredient required 26.8mL of .112 M HCL for complete neutralization. What mass of CaCO3 did the tablet contain?
Does a chemical change occur when you cook an egg? Why or why not? When you fry an egg, it becomes a solid, the heat makes it smoke, and the color changes from clear and yellow to all yellow.
A 3.00-L flask is filled with gaseous ammonia,NH3 . The gas pressure measured at 20.0 deg C is 2.05 atm . Assuming ideal gas behavior, how many grams of ammonia are in the flask?
A sample of Oxygen is collected in a 206 mL container over water at 15C, and the barometer reads 793 torr. What volume would the dry gas occupy at 704 torr and 15C? Water's partial pressure at 15C is 12.8 torr. Answer in units of mL.
Methyl Orange is an acid-base indicator. In dilute solution, at pH greater than 4.4, it is yellow. At pH=3.2 the solution appears red. Draw a structure of the species that is formed at the lower pH of the acid proton adds to the azo nitrogen atom ..
What would be the effect of performing your kinetics experiments at a lower temperature than the one you used?
At equilibrium the vessel is found to contain 0.566 g of H2. Calculate the equilibrium concentrations of H2, Br2, and HBr and Calculate Kc.
Organic chemistry- When 2-butene reacts with hydrogen chloride gas, only one product is detected, whereas when 1-butene reacts similarly
Suppose 50 mL of 0.250 M CoCl2 solution is added to 25.0 mL of 0.350 M NiCl2 solution. Calculate the concentration, in moles per liter, of each of the ions present after mixing.
Suppose 5.00g of Ca is added to 50.0mL of 1.00M HCL. Determine the limiting reactant in this case and number of moles of calcium actually consumed.
