The reaction A -> B is catalyzed by an enzyme that follows Michaelis-Menton kinetics. If the initial rate of the reaction is measured under conditions where [A] = 2/3Km, at what percentage of Vmax will the velocity of the reaction be

The agent of mechanical weathering in which rock is worn away by the grinding action of other rock particles is call

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Suppose a lab group reports a ppercent yield of sand of 105. is it really possible to collect more sand than was originally represented? what is the possible explanation for the extra product?
