In looking for a chemical to replace sodium azide in airbags, suppose that a cheap, nontoxic, and environmentally friendly chemical was found that decomposed more slowly, producing nitrogen over a period of several seconds. Would this chemical be a good replacement for sodium azide in airbags? Explain why or why not.

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.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Ijust took the quiz. their is no coefficient needed. : )

They cool it down and aluminum cools easily
