A 0.853-g of 90.0% lithium chlorate mixture decomposes with heat to give 313 ml of oxygen gas collected over water at 20 c and 762 mmHg .what is the percentage of LiCLO3 in the mixture?
Answer:
[tex]\%LiClO_3=90.4\%[/tex]
Explanation:
Hello!
In this case, since the undergoing chemical reaction is:
[tex]LiClO_4\rightarrow LiCl+\frac{3}{2} O_2[/tex]
It is widely known that when a gas given off from a reaction is collected over water, we can compute its pressure by minusing the total pressure 762 mmHg and the vapor pressure of water at the experiment's temperature (20 °C) in this case 17.5 mmHg as shown below:
[tex]p_{O_2}=762mmHg-17.5mmHg=744.5mmHg*\frac{1atm}{760mmHg}=0.980atm[/tex]
Next, by using the ideal gas equation we compute the yielded moles of oxygen considering the collected 313 mL (0.313 L):
[tex]n_{O_2}=\frac{PV}{RT}=\frac{0.980atm*0.313L}{0.082\frac{atm*L}{mol*K}*293.15K}\\\\ n_{O_2}=0.0128molO_2[/tex]
Now, via the 3/2:1 mole ratio between oxygen and lithium chlorate (molar mass = 90.39 g/mol), we compute the original mass of decomposed lithium chlorate as follows:
[tex]m_{LiClO_3}=0.0128molO_2*\frac{1molLiClO_3}{3/2molO_2}*\frac{90.39gLiClO_3}{1molLiClO_3} \\\\m_{LiClO_3}=0.771gLiClO_3[/tex]
Now, the percentage is computed as shown below:
[tex]\%LiClO_3=\frac{0.771g}{0.853g} *100\%\\\\\%LiClO_3=90.4\%[/tex]

If 150 grams of oxygen are produced, how many moles of sodium chlorate decomposed
Answer:
3.13 moles of sodium chlorate are decomposed.
Explanation:
Given data:
Mass of oxygen produced = 150 g
Number of moles of sodium chlorate decomposed = ?
Solution:
Chemical equation:
2NaClO₃ → 2NaCl + 3O₂
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 150 g/ 32 g/mol
Number of moles = 4.7 mol
Now we will compare the moles of oxygen with sodium chlorate.
O₂ : NaClO₃
3 : 2
4.7 : 2/3×4.7 = 3.13 mol
3.13 moles of sodium chlorate are decomposed.

Is N2 + H2 > NH3 balanced?
Answer:
yes
Explanation:
This can be fixed by multiplying the product contacting nitrogen by 2. o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.

The equilibrium constant, Kc, for the reaction H2 (g) + 2 (g) 2H (g) is 54 at 425 ºC. If the equilibrium mixture contains 0.030 M H and 0.015 M 2 , the equilibrium concentration of H2 is______.
Answer:
[H₂] = 0.0011M
Explanation:
Based on the chemical equation:
H₂(g) + I₂(g) ⇄ 2HI(g)
And Kc is defined as:
Kc = [HI]² / [H₂] [I₂]
Where Kc = 54
And [] represents equilibrium concentration of each compund.
Replacing:
54 = [0.030M]² / [H₂] [0.015]
[H₂] = [0.030M]² / 54* [0.015]
[H₂] = 0.0011M
