Energy Changes In Reactlo Independent Practice
Practice what you learned about energy changes in reactions.
Which is a general chemical equation for an exothermic, single-replacement reaction?
A. AB + C → A+ CB + energy
B. AB + CD + energy – AD + CB
C. AB + C + energy - A+ CB
D. AB + CD AD + CB + energy
SAVE AND CLOSE

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

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.

the answer is barium and copper bromide
