Answer:
positive: proton
negative: electrons
no charge/nuetral: nuetron
Explanation:
no charge could be also described as nuetral.
The balanced equation for the reaction between Ba(OH)₂ and HCl is ;
Ba(OH)₂ + 2HCl ----> BaCl₂ + 2H₂O
When equal volumes of both acid and base are added, the pH is 7 which means its neutral.
This means that the H⁺ ions and OH⁻ are equal and they have neutralised each other. All the ions have reacted to form water molecules.
Dissociation of base and acid are as follows;
Ba(OH)₂ ---> Ba²⁺ + 2OH⁻
1 mol of Ba(OH)₂ dissociates to 2 mol H⁺
HCl ---> H⁺ + Cl⁻
n moles of HCl give out n mol of H⁺ ions
H⁺ = OH⁻ which is why solution is neutral
then OH⁻ moles present are n mol
then Ba(OH)₂ moles present should be n/2 mol
molarity of HCl = 0.5 mol/L
since volumes are equal number of moles are directly proportional to molarity
molarity of Ba(OH)₂ = 0.5/2 = 0.25 M
If enought heat was removed by water, its will probably evaporate or turn into steam.
D) Sulphur i think thats correct
Answer:
Explanation:
Answer:
Its a liquid cause it flows
Explanation:
think about it none of the others make sense ice is a solid and its clear
something like a wall can be thick but it doesn't flow
