Electron is a negatively charged subatomic particle. It orbits the shells of an atom.
Answer:
9.52 kg/mL
Explanation:
Density = mass/ Volume
= 100 kg/ 10.5 mL
= 9.523809524 kg/mL
OR
100 kg = 100 × 10^3 g
》Density = 100 × 10^3 g/ 10.5 mL
= 9523.809524 g/mL
<span>Ba2+(aq)+2I−(aq)+2Na+(aq)+SO2−4(aq)→BaSO4(s)+2I−(aq)+2Na+(aq)
The spectator ions are: </span><span>Na</span>⁺, I⁻.
They appear on both sides of the reaction, hence did not take part in the reaction.
This was clear chemical reaction. The Potassium Chlorate reacted with Oxygen in a combustion reaction to change the chemical structure so that it was able to react with Silver Nitrate.
