From the results, the student calculated that the concentration of the ethanoic acid was 48g. Did the white vinegar contain 5 g of ethanoic acid in 100cm³?

answer; protein;

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.

i wish i could but this one is weird give me abc and i can solve it.
