please help with these questions thank you !
In your experiment you were excpected to observe patterns of reactivity 1) The metal that reacted the most aggressively with water was (Ca, K, Na or Mg). Na The FORMULA for the gas produced when that metal reacted with water was The remaining solution was bsi (neutral, acidic, basic). 0.5 As stated in the lab manual, using your observations you could organize those four metals in order of reactivity. That order should...
Need help. I added the entire page because for some questions,
