<span>KCl<span>O3</span><span>(s)</span>+Δ→KCl<span>(s)</span>+<span>32</span><span>O2</span><span>(g)</span></span>
Approx. <span>3L</span> of dioxygen gas will be evolved.
Explanation:
We assume that the reaction as written proceeds quantitatively.
Moles of <span>KCl<span>O3</span><span>(s)</span></span> = <span><span>10.0⋅g</span><span>122.55⋅g⋅mo<span>l<span>−1</span></span></span></span> = <span>0.0816⋅mol</span>
And thus <span><span>32</span>×0.0816⋅mol</span> dioxygen are produced, i.e. <span>0.122⋅mol</span>.
At STP, an Ideal Gas occupies a volume of <span>22.4⋅L⋅mo<span>l<span>−1</span></span></span>.
And thus, volume of gas produced = <span>22.4⋅L⋅mo<span>l<span>−1</span></span>×0.0816⋅mol≅3L</span>
Note that this reaction would not work well without catalysis, typically <span>Mn<span>O2</span></span>.
Answer:
H2SO4 + 8HI → H2S + 4I2 + 4H2O
Physical properties of matter
'The Sedimentary rock formed from years of sediments piling on top of it and being compressed.'
1) <span>Step 5 A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis. Inorganic carbon is turned into organic.
2) </span><span>Step 1 A caterpillar gets the carbon by eating the tree's leaves. Caterpillar use carbon for energy.
3) </span><span>Step 3 A bird gets the carbon by eating the caterpillar. Organic carbon shifts from one animal to another
4) </span><span>Step 4 The bird flies into a building and dies instantly. It falls to the ground.
5) </span><span>Step 2 The bird decomposes and the carbon is added to the atmosphere. Organic carbon turns into inorganic.
