We did a styrofoam lab to see what hydrides look like when you move across a period. I wanted to know if I drew the last model correctly for group 15. The directions were confusing. I’m supposed to draw the small yellow circles for the hydrogen and the lines represent valence electrons.

Please help me it would be greatly appreciated:)

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

um i think it might be a car?

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
