When a metal reacts with a non-metal, the electrons that are in the metal are transferred to the non-metal which then forms an ion. The compound in the results is called an ionic compound.
Molar mass:
KCl = 74.55 g/mol
KClO3 = 122. 55 g/mol
<span>Calculation of the mass of KClO3 :</span>
<span>2 KClO3 = 2 KCl + 3 O2</span>
2* 122.55 g KClO3 ------------------ 2 * 74.55 g KCl
mass KClO3 ?? --------------------- 25.6 g KCl
mass KClO3 = 25.6 * 2 * 122.55 / 2 * 74.55
mass KClO3 = 6274.56 / 149.1
mass = 42.082 g of KClO3
Therefore:
1 mole KClO3 ---------------------- 122.55 g
?? moles KClO3 ------------------- 42.082 g
moles KClO3 = 42.082 * 1 / 122.55
moles KClO3 = 42.082 / 122.55
=> 0.343 moles of KClO3
Answer C
hope this helps!
Answer:
15L of 0.40M NaCl(aq) solution
Explanation:
2NaCl(aq) + 2H₂O(l) → 2NaOH(aq) + Cl₂(g)
2Na⁺(aq) + 2Clˉ(aq) + 2H₂O(l) → 2Na⁺(aq) + 2OHˉ(aq) + Cl₂(g)
Na⁺(aq) is a spectator ion in the given reaction and does not enter into the reaction process…
Net Ionic Equation is then 2Clˉ(aq) + 2H₂O(l) → 2OHˉ(aq) + Cl₂(g)
From Rxn, 2 moles Clˉ(aq) is needed to produce 1 mole of Cl₂(g)
Therefore, 6 moles Clˉ(aq) is needed to produce 3 moles of Cl₂(g)
That is, 6 moles NaCl(aq) → 6 moles Clˉ(aq) = 0.40M x V(NaCl)liters
V(NaCl) liters = 6 moles Clˉ(aq)/(0.40mole/liter) = 15 liters of 0.40M NaCl(aq)
Sorry, I don’t believe in Jesus or god etc but thnx???
False.
The correct homonym to fit the following sentence should be "led".
She LED her friends through the woods.
A homonym is a word that is said or spelled the same way as another word but has a different meaning.
In the above sentence: lead and led are homonyms. Lead is a heavy metal while led means guided.
Other examples homonyms are:
*lays - to recline
laze - to recline with extreme prejudice
leis - several flower necklaces
*made - accomplished
maid - young woman
*manner - method
manor - lord's house
