Reproducibility is a major principle of the scientific method. It means that a result obtained by an experiment or observational study should be achieved again with a high degree of agreement when the study is replicated with the same methodology by different researchers.
In a closed system, as energy is transformed, it is neither lost nor created. Rather, energy is conserved. Is the force that one surface exerts on another surface when two surfaces rub against each other. When parts of a moving system encounter friction, some of the kinetic energy is transformed into thermal energy.
Oxygen is an example of a gas
Your answer is precipitation.
Are any of the reactants an acid? Can't be a neutralization reaction.
Double replacement reactions are NEVER redox reactions. Process of elimination.
