The double-replacement reaction between silver(I) nitrate and sodium bromide produces silver(l) bromide, a component of photographic film. The balanced reaction is below:

AgNO3 + NaBr → NaNO3 + AgBr

If 3.2 moles of silver(I) nitrate reacts, what mass of sodium bromide is required?

Answer : option c) heat is released during the process.explanation :

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.

C. control over the business

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist

Ibelieve the answer is weathering,hope my answer has you : )
