The mass of a 0.513 mol of Al2O3 is 52.33g.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the molar mass of the substance by its number of moles. That is;

mass of Al2O3 = no. of moles of Al2O3 × molar mass of Al2O3

According to this question, there are 0.513 moles of Al2O3.

Mass of Al2O3 = 0.513 × 102

Mass of Al2O3 = 52.33g

Therefore, the mass of a 0.513 mol of Al2O3 is 52.33g.

Answer:

C) sp2 and sp2

Explanation:

The hybridization depens on the ammount and type of bonds the atom analized has in the molecule.

For example:

  • A C atom bonded to 4 H atoms has a sp3 hybridization.
  • A C atom bonded to 2 H atoms and to 1 C with a double bond (like in ethene) has a sp2 hybridization
  • A C bonded to 1 H and 1 C with a triple bond (like in ethyne) has a sp hybridization.

Analyzing the type and amount of unions of the nitrogen and the carbonyl you will be able to determine the hybridization.

In the imine, the N atom has a double bond to a C and a simple bond two other C, plus the lone pair of electrons (counts as a bond) so it will have a sp2 hybridization.

In the carbonyl, the C has two simple bonds to other C and a double bond to an oxygen atom. It will also have a sp2 hybridization

Answer: 3 <span>moles of water would be produced in present case.
</span>
Reason:
Reaction involved in present case is:
<span>                            C5H12 + 8O2 </span>→<span> 5CO2 + 6H2O

In above reaction, 1 mole of C5H12 reacts with 8 moles of oxygen to give 6 moles of water.

Thus, 4 moles of oxygen will react with 0.5 mole of C5H12, to generate 3 moles of H2O.</span>
