Two weights are tied to the ends of a wire as well as the wire is placed on a block of ice with the weights hanging down over the sides. Ultimately the wire passes through the block, however the block remains intact. The engineering students say it is based on one of the most significant equations in physical chemistry the remaining students in chemistry 201 feel it is "black magic". Who is correct? Explain reasoning
Draw the complete mechanism for the reaction that occurrs in this solvolysis experiment showing all intermediates and using curvy arrows to show electron movement.
One mole of oxygen molecules contains more independent units (O2) than one mole of oxygen atoms (O).
List the following in order of decreasing H3O+ concentration, highest to lowest. A) HC2H3O2, Ka= 1.8x10^-5 B) HClO, Ka= 3.5x10^-8 C) H3BO3, Ka= 7.3x10^-10 D) HC7H5O2, Ka=6.3x10^-5 E) H2S, Ka=1.0x10^-7
1.isomerization of cyclopropane to propene is yielding the activation energy for this process is 274 kjmol. by what
Calculate delta s for reversibly heating 2.000mol of liquid water from 0.00C to 100.00C at a constant pressure of 1.00atm. the specific heat capacity of liquid water is nearly constant and is equal to 1.00cal/kgm or 4.18j/kgm
The combustion reaction produces 2.3x104 J of heat energy. As the gaseous products expand they push against a piston which increases the cylinder volume to 55.0 L.
a gas is collected over water at a certain temperature. the total pressure is 762 torr. the vapor pressure of water at
a certain protein was found to contain 0.639% zinc by mass. Determine the minimum molecular mass of the protein.

Enter balanced molecular, ionic, and net ionic equations for the following pairs of reactants. If all ions cancel, indicate that no reaction (N.R.) takes place.
Useful data might be: change in enthalpy of melting=6.0 kj/mol; change in enthalpy of vaporization=40.6 kj/mol; cp(h2O (liquid))=75.3 J/mol K; the density of ice is 0.917 g/cm^3 and the density of water is 1.00g/cm^3.
