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)
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

Calculate the number of moles of NH3 formed by the reaction of 2 moles of N2 and 2 moles of H2,N2(g) + 3H2(g) forms 2NH3(g)
Answer:
we have to find the number of moles of NH₃ formed by reaction of 2 moles of N₂ and 2 moles of H₂. ... ∴ 2 moles of hydrogen will give = 1.33 moles of ammonia. therefore the no of moles of ammonia after the reaction would be 1.33 moles

Explanation:
Predict the ions that form when magnesium(group IIA) and nitrogen (group VA) react:.
Answer: Mg²⁺ & N³⁻
Explanation:
Since Magnesium is in group 2, then it favors losing two electrons forming a cation with a charge of +2 ( Mg²⁺).
Since Nitrogen is in group VA, it favors gaining three electrons forming the anion with charge -3 (N³⁻).

hi everyone can anyone help with this, the question and diagram is in the pic thx!
Answer:
QP
Explanation:
P has 9 electrons.
Electronic Configuration : 2, 7
Valence electrons : 7
P needs 1 electron to get stable electronic configuration.
Q has 3 electrons.
Electronic Configuration : 2, 1
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,
P + 1 e- -----> P-
Q+ + P- -----> QP

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.
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.

H=11419J/g
a reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken.
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.

in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?
Answer:
When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.
Explain how the fire spreading from tree to tree provides a model for conduction.
The great fire of 1910 burned through parts of north Idaho, western Montana, eastern Washington,and southeastern British Columbia. Many small fires and several large fires that were started by an electric storm coalesced into one”big blowup” of unprecedented size that lasted two days. Hurricane-force winds spread the firestorm; trees became blowtorches, sucking fire from the ground and hurling it in several directions, spreading the fire on contact. Witnesses described fireballs being flung like cannons. Trees exploded like fireworks. The fire killed 87 people, destroyed towns in its path, and burned more than three million acres of forest
the fire spreading is what represents the form of heat transferring from one atom to another within an object and direct contact
what is the molarity of an hcl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400 m naoh? group of answer choices 0.200 m 0.280 m 0.320 m 0.500 m
The molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.320 M.
HOW TO CALCULATE MOLARITY:
The Molarity of an acid when involved in a titration procedure can be calculated by using the formula below:M1V1 = M2V2
Where;
M1 = molarity of acid (M)M2 = molarity of base (M)V1 = volume of acid (mL)V2 = volume of base (mL)According to this question,
M1 = ?M2 = 0.400MV1 = 50 mLV2 = 40 mLM1 × 50 = 0.400 × 40
50M1 = 16
M1 = 16 ÷ 50
M1 = 0.32M
Therefore, the molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.32 M.Learn more at: https://brainly.com/question/8732513?referrer=searchResults
