Chem101 S18 W... 5. Lattice energy is the change i energy that is associated with forming a crystal line lattice of a compound from the gasenus ions. e.g. Na (B) + Cl.(s) ? NaCl(s}. A large negative value of lattice energy means that a lot nf eergy will be given off when the ions coe together to farnm the lattice. Choose the correct option in the statements below a. More energy will be given off when ons have a LARGER/SMALLER...

If they are different gases how can they have the same kinetic energy 15. Select the gas with the highest average kinetic energy per mole at 298 K. ОНа (E)All have the same average kinetic energy. A), O2 B) CO2 C) H20
How can you tell which of the two following equations to use when solving problems and why do the two different equations exist? Why does one have moles and the other mass? How does this affect how we find internal energy for instance? I know that U= Q- W but wouldn't know which Q to use. CynAT specific mass change in heat added heat temperature
Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...

When using the K-map to find the equations for DA and DB for the problem down below, how can you tell which variable is supposed to be for the row and columns? How can I tell if the rows for the 2x4 k-maps would be dealing with "A" while the columns would be dealing with "Bx"? Does it even matter how I set up the K-map? --------------------------------------------------------------------------------------------------------------------------------------------------------- Design a sequential circuit with two D flip-flops A and B, and one...
