Answer:
1. NaI Y AgI
2. K2S Y CuS
3. K2CO3 N
Explanation:
1. When we add NaI to the mixture, the reaction that takes place is:
- NaI(aq) + Ag⁺(aq) → AgI(s) + Na⁺(aq)
Such a reaction does not happen with Cu⁺².
2. When we add K₂S to the mixture, the reaction that takes place is:
- K₂S(aq) + Cu⁺²(aq) → CuS(s) + 2K⁺(aq)
Such a reaction does not happen with Ag⁺.
3. When we add K₂CO₃ to the mixture, the reactions that take place are:
- K₂CO₃(aq) + 2Ag⁺(aq) → Ag₂CO₃(s) + 2K⁺(aq)
- K₂CO₃(aq) + Cu⁺²(aq) → CuCO₃(s) + 2K⁺(aq)
This means both Cu⁺² and Ag⁺ would precipitate, thus they would not be separated.
Answer:
They will be able to produce offspring.
Explanation:
Base on the scenario been described in the question, the correct option to the question is that that they will be able to produce offspring.
When new offsprings a being given birth, what they will be able to do over time is give birth to young offspring like them self when the grow up and mature, because they posses the same genetic materials like their parents.
Answer:
The partial pressure of CO2 is 6,02 atm
Explanation:
This is the formula por partial pressure
=
Total moles ---> 1,5 + 3,5 = 5 moles
Partial pressure CO2 / 8,6 atm = 3,5 moles CO2 / 5 moles (CO2 + Ar)
Partial pressure CO2 = (3,5 moles CO2 / 5 moles) . 8,6 atm = 6,02 atm
When the guard cell is filled with water and it becomes turgid, the outer wall balloons outward, drawing the inner wall with it and causing the stomate to enlarge.
Answer:
c a reaction that requires energy
Explanation:
because it's moving kind of like a human is being more spontaneous by running and or movement it just sounds spontaneous if you think about energy and if you think about the way it works or away human being moved it's hard to explain but it just makes sense why would it be because it's more ordered that one is definitely the one that don't make sense I just don't think it has nothing to do with what it's trying to ask you this answer just makes sense and has a better understanding
