having a lesser value by a process of depletion
Answer:
Many animals have evolved fur or feather colors to blend in with the environment and hide from predators. But how do animals stay camouflaged when their environment changes with each new season? For snowshoe hares, hybridization plays an important role in their ability to match their environment
Explanation:
Answer:
d. the solution is a acid
Answer:
Molecular equation: NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(s)↓
Net ionic equation: Cl⁻(aq) + Ag⁺(aq) → AgCl (s)
Explanation:
We determine the reactants for the reaction:
NaCl and AgNO₃
In aqueous solutions, salts from nitrate are soluble (all soluble)
In aqueous solutions, salts from chloride can make precipitate (with Ag⁺, Pb²⁺ Hg²⁺, Cu²⁺)
We dissociate the reactants:
NaCl → Na⁺ + Cl⁻
AgNO₃ → Ag⁺ + NO₃⁻
Molecular equation: NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(s)↓
To build the net ionic equation we pick up the ions:
Na⁺(aq) + Cl⁻(aq) + Ag⁺(aq) + NO₃⁻(aq) → NO₃⁻(aq) + Na⁺(aq) + AgCl (s)
Those who are solid must be written as a compound, the ions are only from aq solutions. As we find NO₃⁻ and Na⁺ in both sides of the reactions we named them, spectators ions because they do not react. We can cancel them, so the net ionic equation is: Cl⁻(aq) + Ag⁺(aq) → AgCl (s)
