On the space shuttle, lithium hydroxide is produced from lithium oxide and water. the lithium hydroxide then reacts with the exhaled carbon dioxide to remove it from the air supply. the process occurs based on the following reactions: li2o (s) + h2o (g) ĺ2lioh (s) lioh (s) + co2 (g) ĺlihco3 (s) if you have 2.6 g of li2o and 1.3 g of h2o, how many grams of co2 can you remove from the air? report your answer to two significant figures. do not include units in your answer. __1__ g co2

(apex) when a cup of water is dropped, as the cup falls, the water in the cup falls out true or false?

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
