Balloon is filled with helium. At 31 °C pressure is 791 torr and volume is 3.5L. What will be pressure if the balloon rises, so that temperature drops to -5 °C
and volume increases to 5.OL?

What would be the original temperature of a gas that has a volume of 2.0 l and a pressure of 2.0 atm and an unknown temperature that the volume increased to 3.5 l in its pressure decreased to 1.0 atm if the final temperature is measured to be 11°c

State the effect on the concentration of the clo- ion when there is a decrease in the concentration of the oh- ion

Identify the limiting reactant when 9.65-g h2so4 reacts with 6.10-g of naoh.the equation is h2s04 + 2naoh = 2h2o + na2so4• what is the theoretical yield of na2so4, in grams? • how much of the excess reagent will remain after the reaction has been completed? • if 10.5-g of na2so4 are actually recovered experimentally, what is the percent yield?
