Answer:
Sorry I’m not rlly sure but maybe the 2nd or the last
Explanation:
Because if you have a liquid then you need a glass to keep it together and when it is a solid it is already together so you don't need to do anything
Answer:
Plates
Explanation:
The Earth's crust is broken up into sections called plates. Tectonic plates are on the mantle which allow them to move.
Answer:
Sr 2+(aq) + SO42-(aq) → SrSO4(s)
Explanation:
<u>Step 1</u>: Write a properly balanced equation with states:
K2SO4(aq) + Srl2(aq) → 2KI(aq) + SrSO4(s)
<u>Step 2</u>: write the full ionic equation with states. Remember to keep molecules intact. Only states (aq) will dissociate, (s) will not dissociate
. This means SrSO4 won't dissociate.
2K+(aq) + SO42-(aq) + Sr 2+(aq) + 2I-(aq) → 2K+(aq) + 2I-(aq) + SrSO4(s)
<u>Step 3</u>: Balanced net ionic equation
Sr 2+(aq) + SO42-(aq) → SrSO4(s)
Because if the the technique is wrong the scientist is wrong I’m sorry it’s a bad answer :(
