Please answer. I’ll give Brainliest if correct. I’m lost.
Read the chemical equation shown.
2Ag + H2S → Ag2S + H2
Which statement is true about this chemical equation? (5 points)
Ag (silver) is oxidized and H (hydrogen) is reduced.
Ag (silver) is reduced and H (hydrogen) is oxidized.
S (sulfur) is reduced and H (hydrogen) is oxidized.
S (sulfur) is oxidized and Ag (silver) is reduced.
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.
