STP conditions imply a temperature of 273.15 K and a pressure of 100 kPa. When tose conditions are met, 1 mole of any ideal gas will have a volume of 22.7 L. So, if 1 mole occupies a volume of 22.7 L, 2 moles will occupy a volume twice as big. Likewise, 0.5 moles will occupy half the volume 1 mole occupies.
The answer is most likely nonmetals. :)
Answer: Sodium + water → hydrogen gas + sodium hydroxide (aq) + heat [(aq) means “dissolved in water”. It stands for “aqueous”.] If we boil off the water, we will be able to see the sodium hydroxide crystals. The sodium hydroxide is one of the two new substances produced by this chemical change.
Answer:
Hi
The solid is dissolved in the hot, boiling method, the hot mixture is filtered to remove all insoluble impurities, and then the solution is allowed to cool to produce crystallization. All desired substance must be separated in crystalline form and all soluble impurities must remain dissolved in the mother liquors. Finally, the crystals are filtered off and allowed to dry. If a pure substance does not reach a pure substance, the process can be repeated using the same or another problem.
Finally, and once the filtrate cools, said crystals are filtered by means of suction; and washed (cold) in a Büchner to completely remove adhering mother liquors, drying them to remove traces of insulation.
