Answer:
H =2; I = 2; J = 2
Explanation:
Carbon is element 6 in the Periodic Table.
Start at element 1 (H) and count from left to right until you reach element 6 (C).
You get the electron configuration
C: 1s² 2s²2p².
Thus,
H =2; I = 2; J = 2
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
Answer:
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. You might recognize its chemical formula, H2O2, as being similar to that of water (H2O). The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.
