Valence electrons : 1
P needs to loose 1 electron to get stable electronic configuration.
Q donates 1 electron,
Q -----> Q+ + 1 e-
P gains 1 electron,

a reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken.
Answers
Answer:
Exothermic
Explanation:
Bond strength has everything to do with the energy associated with it. What I mean by that, is a stronger bond will require a lot higher of an energy input to break than a weaker bond.
In the same way, energy is released when a bond is made. So, the formation of a stronger bond releases more energy than the formation of a weaker bond.
So, putting the two ideas together, if the bonds formed as stronger than the bonds broken, then more energy is released than taken in, which means energy is released overall over the course of the reaction. This means that the reaction is exothermic.
If there was energy taken in overall, this would be an endothermic reaction.
Let me know if that makes sense, and hope I helped! :)
Exothermic reaction is a reaction in which the bonds formed during the reaction are stronger than the bonds broken.
When chemical reactions occur, there will always be an accompanying energy change.
In exothermic reaction the bonds formed in the products are stronger than the bonds broken in the reactants whereas in endothermic reaction the bonds broken in the reactants are stronger than the bonds formed in the products.

a standard solution is made by diluting a small volume of stock solution. if 2.42 ml of stock solution is mixed with 7.55 ml of water, what is the concentration of the diluted solution? the stock solution concentration is 0.197 m.
Answers
Taking into account the definition of dilution, the concentration of the diluted solution is 0.063 M.
DilutionWhen it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeConcentration of the diluted solutionIn this case, you know:
Ci= 0.197 MVi= 2.42 mLCf= ?Vf= 7.55 mLReplacing in the definition of dilution:
0.197 M× 2.42 mL= Cf× 7.55 mL
Solving:
(0.197 M× 2.42 mL)÷ 7.55 mL= Cf
0.063 M= Cf
In summary, the concentration of the diluted solution is 0.063 M.

A sample of an unknown solid is found to have a volume of 24.3 cm3 and a mass of
217.0 grams. What is the density of the unknown
Answers
Density = mass ÷ volume
= 217.0 g ÷ 24.3 cm³
= 8.93 g/cm³
∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³.1. What amount of ammonia (in moles) is produced by the reaction of 4.00 mol H2 with 3.00 mol Nz?
3 H2(g) + N2(g) → 2 NH3(g)
Answers
3 H₂ + N₂ → 2 NH₃
↓ ↓
4 mol 3 mol
Since the moles of N₂ is the smaller of the two reactants, then N₂ is the limiting factor (the reactant that will decide how much ammonia is produced since it has the smaller amount of moles). ∴ we have to use it in calculating the number of moles of ammonia
The mole ratio of N₂ to NH₃ based on the balanced equation is 1 to 2.
∴ the moles of NH₃ = moles of N₂ × 2
= 3 moles × 2
= 6 moles
