Please help me out! It’s due today!: List one way fluids and non fluids are different

Newtonian fluids have a constant viscosity that doesn't change, no matter the pressure being applied to the fluid. This also means they don't compress. Non-Newtonian fluids are just the opposite — if enough force is applied to these fluids, their viscosity will change

if you mean hydrogen and oxygen then water is the product

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.
