Answer:
Shortest carbon-nitrogen bond = CH3CN, strongest carbon-nitrogen bond = CH3CN
Explanation:
Bond length is defined as the distance between the centers of two covalently bonded atoms, in this case; carbon and hydrogen.
The length of the bond is determined by the number of bonded electrons (the bond order).
The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length.
Therefore, bond length increases in the following order: triple bond < double bond < single bond.
CH3CN - There's a triple bond between Carbon and Nitrogen
CH3NH2 - The bond between carbon and nitrogen is a single bond.
CH2NH - The bond between carbon and nitrogen is a double bond.
The specie with the shortest carbon-nitrogen bond is CH3CN (acetonitrile).
The species with the strongest carbon-nitrogen bond is also CH3CN (acetonitrile) because it contains a triple bond. A triple bond contains one sigma and 2 pi bonds. The energy required to break it is more when compared to the other bonds hence, it is the strongest bond.
Answer:
Explanation: The lowest pressure in a laboratory is 4.0×10^-11Pa
Using Ideal gas equation
PV = nRT
P= 4.0×10^-11Pa
V= 0.020m^3
T= 20+273= 293k
n=number of moles = m/A
Where m is the number of molecules and A is the Avogradro's number=6.02×10²³/mol
R=8.314J/(mol × K)
PV= m/A(RT)
4.0×10^-11 ×0.020 = m/6.02×10²³(8.314×293)
m = 4.0×10^-11×0.020×6.02×10^23 / (8.314×293)
m = 1.98×10^8 molecules
Therefore,the number of molecules is 1.98×10^8
im not sure which one to answer, and i can hardly see the text.
The sun does not orbit anything everything orbits the sun and I don't think the solar system orbits anything I'm sorry
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.
The reaction for this problem is:
H₂ + Cl₂ → 2 HCl
1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.
