Answer:
Sr(s) + C(s) + 3/2 O₂(g) → SrCO₃(s)
Explanation:
The standard enthalpy of formation (ΔH°f) is the energy involved in the formation of 1 mole of a substance from its elements in their most stable states. The chemical equation for the formation of SrCO₃(s) is the following.
Sr(s) + C(s) + 3/2 O₂(g) → SrCO₃(s)
Reactant: <span>Cd(NO^3)^2+(aq)+H^2S(g)
</span>Product: <span>Cds(s)+2HNO^3(aq)</span>
Yes if you build it right it could easily work, i suggest using tape or rope if it's allowed to help support the structure....
