In the equilibrium constant expression for the reaction below what is the correct exponent for n2o4? n2o4 (g) → 2no(g) a) 6 b) 4 c) 1 d) 2

1. list three scientific reasons cockroaches may fly.

May someone me with these science questions

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
