Determine the molarity of a solution that contains 15.50mL of glycerol (C3H8O3, d= 1.265g/mL) in 225.0mL
Problem: When styrene (below) is dissolved in a strong Bronsted-Lowry acid (like HCL), it can be protonated on either of the two carbons in the vinyl substituent, to form two isomeric strong electrophiles (carbocations). (Assume the aromatic C=C π..
A reaction that is used to propel rockets is N2O4(l) + 2N2H4(l) --> 3N2(g) + 4H2O(g). This reaction has the advantage that neither product is toxic, so no dangerous pollution is released
What is the final concentration of copper in the flask b)what is the uncertainty in the value of the copper concentration?
At least how many standard solutions would you need to make calibration graph, assuming that the graph is expected to be a straight line? Explain your answer. Do not include the data from distilled water
A nuclear reaction where the nucleus of an atom splits into smaller parts is known as nuclear fission or nuclear fusion? what is the 10 element on the periodic table? What is a crucible? What is your chemistry teacher name.
If you are given a thermometer with 10 divisions between 10.1 and 10.2 degrees Celsius, and room temperature is exactly 22 degrees Celsius how should you report that value
Explain a girl is celebrating her seventh birthday. Each guest is served one large slice of chocolate cake, a hamburger, French fries and some oranges.
Calculate a lattice energy for CaH2(s) in kilojoules per mole using the following information: (a) Eea for H(g) = -72.8kj/mol. (b) Ei1 for Ca(g) = +589.8kJ/mol.
While 10.0 g of hydrogen gas reacts with 10.0 g of oxygen gas to form water, explain what is the theoretical yield of water
Compute the frequency of light emitted when an electron in hydrogen atom goes from the n = 5 shell to the n = 2 shell.
A solution is prepared from 30g of a non-volatile solute in 10 moles of water. The solution has a vapor pressure of 0.117 atm at 50 deg C. What is the molecular weight of the solute. Note the vapor pressure of pure water at 50 deg C is 0.122 atm.
A typical single drop of liquid water has a volume of approximately 0.05 mL. Assuming the density of liquid water is 1.0 g/mL, how many moles of water are in one drop of liquid, and what volume would this amount of water occupy when vaporized at 1..
