Hg + O2 --> HgO + O
Note that Mercury has a variable valency.
I didn't know if you meant to the power of 14 but if you did here your answer:
3.64 x 10^-19
(you just multiply the frequency by Planck's constant= 6.63 × 10^–34)
Answer: 8 moles
Explanation:
Nc2H6= 4 mol
2C2H6 + 7O2 → 4CO2+6H2O
CO2=4/2⋅4
NCO2= 8 moles
( I write this on paper so the letters and format might be confusing) sorry!!
Answer: Molarity of
in the original sample was 1.96M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
![Molarity=\frac{\text{no of moles}}{\text{Volume in L}}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B%5Ctext%7Bno%20of%20moles%7D%7D%7B%5Ctext%7BVolume%20in%20L%7D%7D)
![{\text {moles of solute}=\frac{\text {given mass}}{\text {molar mass}}=\frac{186g}{95g/mol}=1.96](https://tex.z-dn.net/?f=%7B%5Ctext%20%7Bmoles%20of%20solute%7D%3D%5Cfrac%7B%5Ctext%20%7Bgiven%20mass%7D%7D%7B%5Ctext%20%7Bmolar%20mass%7D%7D%3D%5Cfrac%7B186g%7D%7B95g%2Fmol%7D%3D1.96)
Now put all the given values in the formula of molarity, we get
![Molarity=\frac{1.96}{1.00L}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B1.96%7D%7B1.00L%7D)
![Molarity=1.96mol/L](https://tex.z-dn.net/?f=Molarity%3D1.96mol%2FL)
Thus molarity of
in the original sample was 1.96M
Maalox is the trade name for an antacid and antigas medication used for relief of heartburn, bloating, and acid indigestion in which
4 ml contains
= 320mg of aluminum hydroxide
= 320mg of magnesium hydroxide
= 32mg of simethicone
recommended doses = 4 times * 2 tea spoon = 8 tea spoon/ day
given = 1 tea spoon = 5 ml
8 tea spoon = 40 ml
hence,
amount of aluminum hydroxide = 320/4 * 40 = 3200mg = 3.2 g
amount of magnesium hydroxide = 320/4 * 40 = 3.2 g
amount of simethicone = 32/4 * 40 = 320 mg = 0.32g
