Why amorphous solids are called super cooled liquids?

The density of lead is 11.3 g/mL . The water level in a graduated cylinder initially at 206 mL rises to 287 mL after a piece of lead is submerged. What is the mass in grams of the lead?

What does a substance in solid fase has

Use the problem below to answer the question: 34 grams of carbon react with an unlimited amount of H2O. The reaction is: C + H2O → CO + H2 The equation is balanced. The starting substance is carbon, C. The ending substance is hydrogen, H2.

Predict whether the reaction will take place Ag+NaNO3 → AgNO3+Na yes no

the pressure of the compressed gas is 3.00 atm. if the area of the piston is 0.0590 m^2, what is the force exerted by the gas on the piston in Newton's

In the equilibrium and concentration gizmo, you learned that you can predict the direction of a reaction by comparing the reaction quotient (qc) with the known equilibrium constant kc. you can do the same thing using partial pressures:
