What's in diapers?

A chemical property describing the ability to catch fire and burn

10. Is the identity of an element determined by its mass number or atomic number? By omak

Why do elements in the same group have a similar reactivity?

If 1 mole of gas occupies 22.4 liters of space calculate the number of moles that will occupy 11.2 liters of space? Show work.

What is the most striking part of this simulation?

what is the volume of 0.98 mol oxygen (O2) gas at 275 K and a pressure of 2.0 atm? (the universal gas constant is 0.0821 L*atm/mol*K)

A student asks you for a simple rule to tell apart plants cells and animal cells when viewed under a microscope. Describe such a rule.

Phosphorus tribromide decomposes to form phosphorus and bromine, like this: 4pbr3 (g) → p4 (g) + 6br2 (g) write the pressure equilibrium constant expression for this reaction

Step I of the proposed mechanism involves the collision between NO2 and F2 molecules. This step is slow even though such collisions occur very frequently in a mixture of NO2 (g) and F2 (g).

A 500-g sample of Al2 (SO4) 3 is reacted with 450 g of Ca (OH) 2. A total of 596 g of calcium sulfate is produced in the laboratory. What is the percent yield?
