Before you can predict if an object will sink or float in a liquid, what do you need to compare? 1 You must compare the size of the object to the density of liquid.

2 You must compare the density of the object to the amount of liquid.

3 You must compare the density of the object to the density of liquid.

4 You must compare the mass of the object to the amount of liquid.

Explain two reasons you think it is important for scientists to search for new ways to treat cancer

Which statement best explains why cells were observed in more detail using a compound microscope than a simple microscope? a compound microscope has greater magnification ability than a simple microscope. the compound microscope was invented before the simple microscope. a compound microscope is much easier to manufacture than a simple microscope. compound microscopes were more common than simple microscopes.

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
