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.
Answer:
An unbalanced single replacement reaction
Answer : The characteristic properties of a substance always remains the same irrespective of the sample being observed is large or small.
Few examples of characteristic properties of any substances includes freezing or melting point, boiling or condensing point, density, viscosity and solubility. They are specific for specific substances and which makes them easily recognizable.
Whereas chemical properties are specific for one substance which chemically transformed into another substances.
Answer:- 
Explanations:- Lattice energy depends on two factors, charge and size.
High charge and small size gives higher lattice energy where as low charge and bigger size gives lower lattice energy.
in LiCl, NaCl and KCl, the anion is same and also the charges for Li, Na and K are also same. The deciding factor here is the size of cations. Since the size increases as we move down a group, the order of size of these three atoms is Li<Na<K.
The order of lattice energy is exactly opposite as it's increases as the size decreases.
Now, if we look at magnesium chloride and strontium chloride then again the anion is common but the metals have higher charge as compared to the alkali metals(Li, Na and K). So, lattice energy values must be higher for these two compounds. If we compare Mg and Sr then size of Mg is smaller and so the lattice energy would be greater for this.
Hence, the increasing order of lattice energy is .
