Interpretation:
The moles of
Concept introduction:
If a compound is formed from two elements and the amount of one element is known, then the amount of another element is determined from the molar ratio of both metals in the compound. Suppose the compound is
(b)
Interpretation:
The mass of
Concept introduction:
Following are the step to calculate the mass of an element present in the compound if the amounts of its constituent elements and the mass of the compound are known.
Step 1: Determine the amount of each element present in the compound and convert moles ot mass by using the following expression,
Step 2: Subtract the known mass of element from the mass of the compound to determine the unknown mass of another element. Suppose the compound is
(c)
Interpretation:
The element represented by the symbol M is to be determined.
Concept introduction:
Molar mass is defined as the mass of

ALEKS 360 for Silberberg Chemistry: The Molecular Nature of Matter and Change
- (15 pts) Consider the molecule B2H6. Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book? Sketch the new highest occupied and lowest unoccupied MOs for the molecule (B2H6).arrow_forwardQ8: Propose an efficient synthesis of cyclopentene from cyclopentane.arrow_forwardQ7: Use compound A-D, design two different ways to synthesize E.
