Calculate the standard biological Gibbs free energy for the reaction: pyruvate- + NADH + H+(aq) ---> Lactate- + NAD+ at 309 K given that the standard Gibbs free energy = -65.0 kJ/mol at this temperature. This reaction occurs under conditions of low oxygen supply, such as in muscle cells during strenuous exercise. Note: See Box 7.1 on page 164. The biological standard state has hydrogen ions at 1x10-7 molar instead of 1 M.

Suppose you discovered a new element with 120 protons and 2 electrons in its outer level . i'm what group does this new element belong? what properties would you expect it to have

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
