The following unbalanced equation is performed in a laboratory:
Mg (s) + HCl (aq) --> MgCl2 (aq) + H2(g)
If you begin with 10.0 grams of each reactant, how many grams of hydrogen gas should you expect to measure in your experiment? Enter only the number, rounded to the correct number of significant figures.
What volume will a sample of hydrogen occupy at 28.0 degrees celsius if the gas occupies a volume of 22.3 dm3 at a temperature of 0.0 degrees Celsius. assume that the pressure remains constant
Write a balanced chemical reaction for the formation of a free fatty acid from a soap molecule under acidic conditions.
Adding magnesium ribbon (about .5g) in a solvent of 100mL of HCl acid in a polysterne cup as my calorimeter. my question is why and how would my calculated anthalpy of reaction be inaccurate if:
a large cylinder of He gas,such as that used to inflate balloons,has a volume of 25.0 L at 22c and 5.6 atm. How many moles of He are in such a cylinder
A white solid, soluble in water and alcohol but not in toluene, does not melt when heated to 250°C. However, upon prolonged heating of the solid a colorless gas evolves and the amount of solid "shrinks". The solid appears in the list of pure subst..
What mass of salt (NaCl) should you add to 1.96L of water in an ice cream maker to make a solution that freezes at -10.2C. Assume complete dissociation of the NaCl and density of 1.00 g/mL for water.
Problem- If 200 ml of some Pb(NO3)2 solution is mixed with 600 ml of 1.10 x 10-2 M NaCl solution, what is the maximum concentration of the Pb(NO3)2 solution added if no solid PbCl2 forms? (Assume Ksp = 2.00 x 10-5 M at this temperature.) Enter the..
What is a reaction equation that would support the explanation? could you use NaOH instead of NaHCO3? Explain
Calculating Volume Needed for Level of pH, A 1.00g sample of benzoic acid (C6H5CO2H, FW = 122.12g/mol,Ka = 6.5 x 10^ -5) is dissolved in water to give a solution with a volume of 500mL.
What is the pH of a solution obtained by adding 75.0mL of 0.366M CsOH to 250.0 ml Ba(OH)2 solution with a pH of 11.65.
Explain how these products are produced by showing the mecahnism involved. (draw).
Explain how and why the nature of the leaving group affects the rate of an Sn1 reaction. Would 2-iodo-2-methylpropane react faster or slower than the other alkyl halides
