Answer:
2040 cm-1
Explanation:
The vibrations frequency is obtained from;
v=1/2πc √k/μ
Where;
k= force constant = 240kgs-2
μ= reduced mass = 1.627×10^-27 kg
c= speed of light= 3×10^10cms-1
v= 1/2×3.142×3×10^10√240/1.627×10^-27
v= 5.3×10^-12 × 3.84×10^14
v= 20.4×10^2
v= 2040 cm-1
Carbon Dioxide has two polar C=O. bonds, but the geometry of Carbon dioxide is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.
I hope this helps :)
<span>Answer:
Here is a more complex redox reaction involving the permanganate ion in acidic solution:
5Fe2+ + 8H+ + MnO4 --> 5Fe3+ +Mn2+ + 4H2O
Classify each reactant as the reducing agent, oxidizing agent, or neither.</span>
N(C): N(H)=n(C): n(H)=6: 10
3×10²¹: x=6: 10
x=5×10²¹
Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams
This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
hope this helps have a awesome night/day❤️✨
