Calculation indicates that 82.2 g of zinc should be obtained from a certain reaction if the chemist kids 39.7 g what is the yield percent??

i'm pretty sure its b i might be wrong though!

the ratio of the conjugate base to the acid required to attain the desired ph.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
