2KCLO3(s) --> 2KCL(s) + 302(g) Molecular oxygen is produced by the decomposition of KClO3. How many liters of O2 are produced by the complete decomposition of 100.0 g of KCLO3 at STP?

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )

What must be in balance for temperatures to remain constant?
