(a) Write an equation for the reaction. How much O2 could be produced from 2.50 g of KO2 and 4.50 g of CO2?4 KO2 (s) + 2 CO2 (g) → 2 K2CO3 (s) + 3 O2 (g) Carbon dioxide is wet.

KO2 + O3 = KO3 + O2 (until 0°C, in the liquid CCl2F2). It takes formals of CO two to react with two moles of co two, so we need to multiply that number by two. 2KO2 + H2SO4 (anhydrous) = K2SO4 + O3↑ + H2O (normal temp.). Still have questions? And now we have to remember that our mass is just number of moules climes, molecular weight.

(12 pts.) The density of $\mathrm{KO}_{2}$ at $20^{\circ} \mathrm{C}$ is $2.15 \mathrm{g} / \mathrm{cm}^{3}$. to form potassium carbonate and oxygen: Potassium superoxide was used as an oxygen source on early manned missions of the Soviet space program, for firefighters, and for mine rescue.

Potassium superoxide is sensitive to moisture in the air.

Hence, it acts as limiting reagent. Potassium superoxide is used as a CO 2 scrubber, H 2 O dehumidifier and O 2 generator in rebreathers, spacecraft, submarines and spacesuit life support systems ! Okay, and now t work out the Mass.

So that's just going to be our baby a 0.0. Well, we've just got them all already inserted there. Potassium superoxide is a strong oxidant, able to convert oxides into peroxides or molecular oxygen. It looks like this, but scientific notation is a more communion notation in general when you start getting lots of decimal places, okay, so how many moles of Ko to are we consuming? 4KO2 (s) + 2 CO2 (g) ---> 2K2CO3 (s) + 3O2 (g) This reaction makes potassium superoxide useful in a self-contained breathing apparatus.

The figure shows an initially stationary block of mass please provide all the steps Potassium superoxide, $\mathrm{KO}_{2},$ is often used in oxygen masks (such as those used by firefighters) because $\mathrm{KO}_{2}$ reacts with $\mathrm{CO}_{2}$ to release molecular oxygen. Reacts with water, acids, mono-and carbon dioxide, ozone, potassium, ammonia. But at the moment it's convenient to have the mass in grams because that works with are forms. How much O 2 (in grams) could be produced from … the CO2 exhaled by a person and replaces it with oxygen according So for Ko to the molecular weight is going to be 39 poin 010 That's the atomic weight of that has waas twice oxygen, which is 16. It has the ionic structure (K +) (O2-).

(Not including theoretical, just ones we know about or have made or discovered so far). It reacts with carbon dioxide in respired (exhaled) air to form potassium carbonate and oxygen gas. The superoxide consumes the $\mathrm{CO}_{2}$ exhaled by a person and replaces it with oxygen.$$4 \mathrm{KO}_{2}(\mathrm{s})+2 \mathrm{CO}_{2}(\mathrm{g}) \longrightarrow 2 \mathrm{K}_{2} \mathrm{CO}_{3}(\mathrm{s})+3 \mathrm{O}_{2}(\mathrm{g})$$What mass of $\mathrm{KO}_{2}$, in grams, is required to react with $8.90 \mathrm{L}$ of $\mathrm{CO}_{2}$ at $22.0^{\circ} \mathrm{C}$ and $767 \mathrm{mm}$ Hg?

And here I am going to put in the units divided by 44 point one grams horrible. Do radioactive elements cause water to heat up? To see how... broadband telecommunications technology and management book ch

So we want to multiply that by our 1 30 a point 21 grams curveball, Remember, this is moles here, So our walls were going to cancel and we're left with an answering grams which is nine point seven one nine times, 10 to the minus for grams.

We're last with one point or zero said it.

4.0, ANSWER: Molar Molar the mass of KO₂ = 71 g mass of co₂ = 44 g given equation - from 2 KO2 + co2 K₂CO3 +3,02 So, & un g co reacts with 2x71 g KO₂ 4.62 g co₂ reacts with 2x71 x 4.62 g 44 i e., 14.91 g KO₂ But only 2.45 g of ko, is available. This is just say it's 1.0 kilograms because there are 1000 grams in a kilogram and that would be a more usual way to write it. And that gives us 71.1 and you'll notice I've conveniently put the units over here so I don't need to write them every time. The orange-yellow, decomposes when heated, melts under excess pressure. We know we wanted a number Ingram's and that gives us. I have a 1993 penny it appears to be half copper half zink is this possible? Hydrolysis gives oxygen gas, hydrogen peroxide and potassium hydroxide: eval(ez_write_tag([[468,60],'homeworklib_com-large-leaderboard-2','ezslot_12',136,'0','0'])); 7.37. But if we want to get rid of that fractional coefficient which is just tidy or sometimes we could multiply everything by two and so are balanced, reaction is going to be four and to and to on three. Potassium superoxide $\left(\mathrm{KO}_{2}\right),$ a useful source of oxygen employed in breathing equipment, reacts with water to form potassium hydroxide, hydrogen peroxide, and oxygen.

So we need to again look at the stoke you metric coefficients. Still have questions? 17. It is a strong oxidizing agent. It is used in submarines, space vehicles, space suits, and by firefighters and miners.
