What’s the percent by mass of carbon in c10h14n2

Chemistry
1 answer:
stepladder [879]4 years ago
3 0

Answer:

the answer is 74.03%

Explanation:

Add all the masses together, M of C = 120.1, M of  H = 14.4 and M of N = 28.02. Adding all those together will give you the mass of the compound, then u divide the mass of carbon by the mass of compound and multiply by 100 to get the percent by mass.

120.1 + 14.4 + 28.02 = 162.26

120.1/162.26 x 100 = 74.03%

Select the electron-domain geometry for a molecule with three bonding domains and one nonbonding domain.
mamaluj [8]

Answer: C) Tetrahedral

Explanation:

The number of electron pairs is 4 that means the hybridization will be sp^3 but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.

Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be sp^2.

Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be sp^3.

Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be sp^3d.

Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be sp^3d^2.
