How many moles of oxygen are produced by the decomposition of six moles of potassium chlorate?
You started with 6 equiv chlorate, and thus 9 equiv dioxygen gas are evolved.
How many moles of oxygen can be obtained by the decomposition?
The correct answer of this question is 5 moles of oxygen gas can be produced during the electrolytic decomposition of 180 g of water.
How many moles of potassium nitrate are produced when?
So clearly 1 mole of each reactant combines to form 3 moles potassium nitrate and 1 mole aluminium phosphate. Hence, by ratio and proportion, 2 moles of each reactant will produce 6 moles potassium nitrate and 2 moles aluminium phosphate.
How many moles of oxygen are produced when 3.0 moles of potassium chlorate decompose completely?
(3/2)*(3.0) moles O2, or 4.5 moles of O2.
How many atoms are in 3.75 moles?
There are 2.26 x 1024 carbon atoms in 3.75 moles of carbon. A mole is defined as 6.022 x 1023 elementary entities of a…
Is 2 KClO3 → 2 KCl 3 O2 balanced?
1 Expert Answer
2KClO3 ==> 2KCl + 3O2 This is the correctly balanced equation. If you look at it, it tells you that TWO moles of KClO3 decompose to produce TWO moles of KCl and 3 MOLES of O2.
How many grams of oxygen can be produced from the decomposition of KClO3?
1 g of KClO3 would yield 0.783353733 g of O2.
How much oxygen will be obtained by the complete electrolysis of 90 kg of water 2h2o → 2h2 O2?
H2O → H2 + O2
In water, the ratio of the mass of hydrogen to that of oxygen is 1:8. So, when water decomposes, it produces hydrogen and oxygen in the ratio of 1:8. So, when 90 kg of water decomposes, 10 kg of hydrogen and 80kg of oxygen is produced.
How many moles of oxygen are evolved?
How many moles of oxygen are evolved? 1 Expert Answer Assuming that only oxygen evaporated, you can figure out the moles by dividing the difference in weight of the mixture by the molecular weight of the oxygen. So the answer would be (23.584-22.347)grams divided by 16.000 g/mol, or 7.7313×10^-2 moles O2.
How many moles of oxygen atoms are in 90 grams of water?
A mole of a compound is a number of grams equal to the atomic weight of a molecule of the compound, so for water we have 2 hydrogen atoms and one oxygen, so the atomic weight of water is 1+1+16=18, so a mole of water is 18 grams. We have 90g of water so we have 90/18 = 5 moles of water.
