The mass spectrum of BC13 contains 8 peaks. Considering that boron has two common isotopes, 10B and 11B, and chlorine has two common isotopes, 35Cl and 37Cl, what will be the molar mass range in which you would expect to observe these 8 peaks?

If equal masses of the listed metals were collected , which would have a greatest volume ? a. aluminum 2.70,b.zinc7.14,c.copper 8.92,d.lead 11.34

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )
