Best Answer: <span>We would write the molecular equation as ....
BaCl2(s) + H2SO4(aq) --> BaSO4(s) + 2HCl(aq)
You would write the ionic equation as....
BaCl2(s) + H+ + HSO4^- --> BaSO4(s) + 2H+ + 2Cl-
remove the H+ from both sides and write the net ionic equation as.....
BaCl2(s) + HSO4^- --> BaSO4(s) + H+ + 2Cl-
If you placed BaCl2 solid in sulfuric acid it would quickly acquire a coating of insoluble BaSO4 which will prevent the further reaction of the barium chloride.
The same is true if you took a block of BaCl2 and placed a drop of H2SO4 solution on it. The solid BaSO4 that forms will block further reaction. You would get HCl gas only if the small amount of solution became saturated in HCl.</span><span>

Hello!
We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:
The molar mass of of magnesium = 24.30 g/mol
If:
1 mol we have 6.02*10²³ atoms
1 mole of Mg we have 24.30 g
Then we have:
24.30 g ------------- 6.02*10²³ atoms
x ----------------------- 7.43*10²² atoms
I Hope this helps, greetings ... DexteR! =)
I’m pretty sure it is 50%50%. can you please mark me the brainliest. have a great day and good luck with school. :)
Answer: This is true.
Explanation:
It is true because if becomes frozen, then it is physically harder to melt...
