Ok I’m not gonna do anything with my phone I’m gonna send you a picture
Answer:
Yes.A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element.
Answer:
- HNO3(aq)+NH3(aq)→NH4NO3(aq)+H2O(l): neutralization.
- 2Cu(s)+O2(g)→2CuO(s): redox.
- NaCl(aq)+AgNO3(aq)→NaNO3(aq)+AgCl(s): precipitation.
- 2LiOH(aq)+H2SO4(aq)→Li2SO4(aq)+2H2O(l): neutralization.
- CaCl2(aq)+K2CO3(aq)→2KCl(aq)+CaCO3(s): precipitation.
Explanation:
Hello,
Based on the given reaction and their classification as redox, neutralization or precipitation, one obtains:
- HNO3(aq)+NH3(aq)→NH4NO3(aq)+H2O(l): neutralization as ammonia which is a base, is reacting with nitric acid which is an acid to yield ammonium nitrate which is a base.
- 2Cu(s)+O2(g)→2CuO(s): redox as both copper's and oxygen's oxydation states change by increasing by 2 and reducing by 2 respectively.
- NaCl(aq)+AgNO3(aq)→NaNO3(aq)+AgCl(s): precipitation as the inital reactants are soluble but the yielded silver chloride is not.
- 2LiOH(aq)+H2SO4(aq)→Li2SO4(aq)+2H2O(l): neutralization as lithium hydroxide which is a base reacts with sulfuric acid which is an acid to yield lithium sulfate which is a salt.
- CaCl2(aq)+K2CO3(aq)→2KCl(aq)+CaCO3(s): precipitation since both calcium chloride and potassium carbonate are soluble whereas calcium carbonate is not.
Best regards.
