co2 + 2lioh = li2co3 + h2o
to ensure that the air in the shuttle remains free of excess co2, engineers test the air-purification system.
they combine 1.000 × 10^3 g lioh with 8.80 × 10^2 g co2. the reaction produces 3.25 × 10^2 g h2o.
what is the theoretical yield of this test reaction? record answer to the nearest whole number.
_g h2o

Answer : The theoretical yield of water in this reaction is 360 g.

Solution : Given,

Mass of

Mass of

Mass of

Molar mass of = 44 g/mole

Molar mass of = 24 g/mole

Molar mass of = 18 g/mole

First we have to calculate the moles of and .

Moles of =

Moles of =

The given balanced chemical reaction is,

From the given reaction, we conclude that

1 mole of react with 2 mole of

20 moles of requires of

But the actual moles of = 42 moles

Excess moles of = 42 - 40 = 2 moles

So, is the limiting reagent.

Now we have to calculate the mass of .

From the reaction, we conclude that

1 mole of gives 1 mole of

20 moles of gives 20 moles of

Mass of = Moles of × Molar mass of  

Mass of = 20 moles × 18 g/mole = 360 g

The experimental yield of = 325 g

Therefore, the theoretical yield of = 360 g

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
