Why do the reactants nai(sodium iodide) and agno3(silver nitrate) indicate the reaction of double displacement?

Explanations:- If a reaction looks like, then it is called double displacement reaction as two ions are exchanged in this reaction.

When sodium iodide and silver nitrate are added then a double displacement reaction takes place where iodide ion goes from sodium to solver and nitrate ion from silver to sodium. A precipitate of silver iodide forms in this reaction.

if you mean hydrogen and oxygen then water is the product

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
