Iam doing an experiment that calls for 200g of h₂so₄. how many moles of h₂so₄ is this? show your work. * 2 points 19,614 moles 2.02 moles 6.02x10²³ moles 7 moles

The following reaction shows sodium carbonate reacting with calcium hydroxide. na2co3 + ca(oh)2 → naoh + caco3 how many grams of naoh are produced from 20.0 grams of na2co3? (molar mass of na = 22.989 g/mol, c = 12.01 g/mol, o = 15.999 g/mol, ca = 40.078 g/mol, h = 1.008 g/mol) 12.2 grams 15.1 grams 24.4 grams 30.2 grams

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.

Just on number 2 (all parts), and if you do answer explain in detail
