Please help!! Approximately what is the minimum temperature needed to dissolve 10 g of KNO3 in 100 g H2O?

Round your answer to the nearest whole number and type in the number only; no units.

Answer explain why it is not possible to deduce a complete order of reactivity.

How many moles of sulfuric acid (h2so4) are needed to react completely with 6.8 moles of lithium hydroxide (lioh)? 2lioh + h2so4 → li2so4 + 2h2o a. 3.4 mol h2so4b. 6.8 mol h2so4 c. 10.2 mol h2so4 d. 13.6 mol h2so4

Do polar molecules have ionic bonds?
