3.4: Identifying Molecular and Ionic Compounds

WebYou can often recognize ionic compounds because of their properties. Ionic compounds are solids that typically melt at high temperatures and boil at even higher temperatures. For example, sodium chloride melts at 801 °C and boils at 1413 °C. (As a comparison, the molecular compound water melts at 0 °C and boils at 100 °C.) WebMar 28, 2024 · You can determine the number of moles based on the pressure, volume, and temperature provided by the experimental data. The number of moles can be calculated using the following formula: n = PV/RT. [2] In this formula, n is the number of moles, P is the pressure, V is the volume, T is the temperature in Kelvin, and R is the gas constant. pool sounds effects
