P(total)=P1+P2+P3+...
P(total)=P(N2)+P(others)+P(O2)
100kPa=78kPa+1kPa+P(O2)
P(O2)=100-79=21kPa
The latent heat is correlated with energy as follows:
Q = mL
550 * 103 = 14 * 103 * L
L = 39.285 J /g
Thus, latent heat of the substance is 39.285 j /g
<u>Given:</u>
Concentration of Na₂S = 0.765 M
Volume of Na₂S solution = 25.0 ml = 0.025 L
Final total volume = 225 ml = 0.225 L
<u>To determine:</u>
The concentration of Na+ ions
<u>Explanation:</u>
# moles of Na₂S = 0.765 * 0.025 = 0.0191 moles
Based on the atomic stoichiometry of Na₂S-
# moles of Na⁺ ions = 2*0.0191 = 0.0382 moles
conc of Na⁺ ions = 0.0382 moles/ 0.225 L = 0.169 M
Ans: [Na⁺] = 0.169 M
Answer:
You would put the 4 quantum numbers corresponding to the electrons being described above
Explanation:
Quantum numbers refer to electrons, so I'll assume you mean the electron number that would correspond with the atomic number of the element. Quantum numbers are basically like an address for electrons, giving us information about the location of an electron from most general to most specific.
Soluble means that something will "dissolve" in a substance (typically water). This means that the substance is polar (like water)
insoluble is the opposite of soluble. It means that a substance will not dissolve in water. This means this is non-polar
Hope this helped!
