Molecular orbitals are similar to atomic orbitals is that:.
A. They can hold two electrons of opposite spin.
B. In general, bond order is related to bond strength.
C. We refer to molecular orbitals in which the greatest electron probability is between the nuclei as sigma molecular orbitals.
D. Pi orbitals are antibonding orbitals.
E. Atomic orbitals are lower in energy than bonding molecular orbitals.
F. None of the above statements is true.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

i believe the answer is true.
