For the reaction shown, calculate how many grams of oxygen form when each quantity of reactant completely reacts.
2 kclo3(s) → 2 kcl(s) + 3 o2(g)
2.72 g kclo3
0.361 g kclo3
83.6 kg kclo3
22.5 mg kclo3

Answer :

The mass of oxygen form from 2.72 g is 1.06 grams.

The mass of oxygen form from 0.361 g is 0.141 grams.

The mass of oxygen form from 83.6 kg is 32.7 kilograms.

The mass of oxygen form from 22.5 mg is 8.81 milligrams.

Explanation :

The given chemical reaction is:

Molar mass of = 122.55 g/mol

Molar mass of = 32 g/mol

For 2.72 g :

From the balanced chemical reaction we conclude that,

As, grams of decomposes to give grams of

So, grams of decomposes to give grams of

Thus, the mass of oxygen form from 2.72 g is 1.06 grams.

For 0.361 g :

From the balanced chemical reaction we conclude that,

As, grams of decomposes to give grams of

So, grams of decomposes to give grams of

Thus, the mass of oxygen form from 0.361 g is 0.141 grams.

For 83.6 kg :

From the balanced chemical reaction we conclude that,

As, grams of decomposes to give grams of

So, of decomposes to give of

Thus, the mass of oxygen form from 83.6 kg is 32.7 kilograms.

For 22.5 mg :

From the balanced chemical reaction we conclude that,

As, grams of decomposes to give grams of

So, of decomposes to give of

Thus, the mass of oxygen form from 22.5 mg is 8.81 milligrams.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
