🔴 10 AS Chemistry formulae to solve any mole problem in half the time In this video, I break down the must-know AS/IAL Chemistry (WCH11) formulae that repeatedly appear in exams and show you exactly when to use each one for fast marks. You’ll learn how to handle counting particles using Avogadro’s constant, convert moles ↔ gas volume at room conditions (24 dm³), use and rearrange the ideal gas equation, and avoid the common unit mistakes (Pa, m³, K). We also cover the core quantitative formulas

My Concert Stage Lego MOC - Part 16 Please like, follow and subscribe for more updates and other creations. I update often. Today I was able to solve the lower roofs to the side of the main part of the stage and to finish the ramps to the floor on both sides. If you have any thoughts on it, good or bad, please write in the comments section, I’d love to hear from you. #lego #legobuilder #moc #legomoc #concert
