Given that you have 14.5 moles of n2, how many moles of h2 are theoretically needed to produce 22.5 moles nh3 according to the reaction n2 + 3 h2 → 2 nh3 ? 1. 21.8 moles h2 2. 33.8 moles h2 3. 43.5 moles h2 4. 2.33 moles h2 5. 78.8 moles h2 6. 15.0 moles h2 7. 489 moles h2

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

Consider the elements bromine and chlorine; which elements has a larger ionic radius ?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
