How many electrons are shared between one nitrogen atom and one carbon atom? two three six seven
the nitrogen and the carbon are sharing six electrons! A single bond is created when two atoms share two electrons. If they share four, their bond is doubled. These two are actually sharing a six, which is a triple bond.
How many electrons does the carbon atom share?By sharing four pairs of electrons through the formation of four covalent bonds, carbon fills its outer energy level and achieves stability.
How many electrons do nitrogen atoms share?Only the nitrogen atoms' valence shells are taken into account while thinking about the bonding in a nitrogen molecule. Eight electrons can fit in total in nitrogen's outer shell. Therefore, the nitrogen atoms share three electrons each in order to produce the most stable structure.

4. How much energy will it take to raise the temperature of 75.0 g of water from 20.0 °C to 55.0 °C?
Specific heat of water = 4.184 J/(g°C)
A. 63 J
B. 630 J
C. 2630 J
D. 1.1 x 10¹ J
Answer:
1.1 x 10⁴ J
Explanation:
To calculate eth energy needed, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat (4.184 J/g°C)
-----> ΔT = change in temperature (°C)
You can plug the given values into the equation and solve.
Q = mcΔT
Q = (75.0 g)(4.184 J/g°C)(55.0 °C - 20.0 °C)
Q = (75.0 g)(4.184 J/g°C)(35.0)
Q = 11,000 J
Q = 1.1 x 10⁴ J

Why is an aqueous solution of potassium hydroxide an unsuitable medium for effecting the base promoted elimination of the E2 reaction procedure
The potassium hydroxide is an unsuitable medium because an aqueous solution medium is highly polar in nature, so there will be a high tendency for carbonation to be formed and prefer substitution reaction rather than an elimination reaction.
The potassium hydroxide is an unsuitable medium for effecting the base-promoted elimination due to the fact that alkoxide anions aren't only more basic than the pure hydroxyl group, but they may be also bulkier. The higher bulkiness makes it a worse nucleophile than hydroxyl and the higher basicity makes it better at E2 eliminations.
A substitution reaction is a form of Chemical reaction in which the functional group of 1 chemical compound is substituted by means of any other group or it's miles a reaction that involves the substitute of one atom or a molecule of a compound with another atom or molecule.
Carbonation is the chemical reaction of carbon dioxide to provide carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.

2/16 = (1/2)^n
1/8 = (1/2)^n
log (1/8) = log (1/2^n)

What is Limiting reagent?The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. The precise quantity of reactant required to react with another element may be estimated from the reaction stoichiometry.
How do you identify a limiting reagent?
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
Start by writing the balanced chemical equation that describes this reaction
[tex]2Na_{(s)} + Cl_{2 (g)} -- > 2NaCl_{(s)}[/tex]
Notice that the reaction consumes 2 moles of sodium metal for every 1 mole of chlorine gas that takes part in the reaction and produces 2 moles of sodium chloride.
now we can see that we have 3 moles of sodium and 3 moles of chlorine, according to question. so, we can say that sodium is the limiting reagent in the given situation.
