The molecule below contains both an aldehyde and a ketone functional group. select only the carbonyl carbon atom of the aldehyde functional group. identify the carbon atom by selecting the atom and assigning it a map number of 1.

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).
