When Rutherford shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that this meant there was a tiny, dense nucleus that was causing these deflections.
Answer:
ionic, BRAINLIEST PLZ
Explanation:
ionic is slightly charged particles, and absorbing an o atom creates a slight negative charge, there are no shared atoms, so it is not covalent, and the other two are just add ons
when you hit a chemical with hammer and it was frozen only its physical properties will change and not he chemical properties,
when heated it may decompose to other chemical
when you hit with hamer it physical appearance will change but it remains chemically the same
when you put in salt solution , it wil interact with ions and its chemical properties changes
similarly when it was frozen, it retains its chemical properties.
Hi!
When titrating Calcium and Water solution, if there is some CaCO3 in the solution, the following reactions may occur in acid solution:
CaCO₃ + H⁺ → Ca⁺² + HCO₃⁻
HCO₃⁻ + H⁺ ↔ H₂CO₃ → CO₂ (g) + H₂O
The bubbles are from CO₂ that is being developed from an acidic solution of CaCO₃
