Answer:
439.7nm
Explanation:
Energy of a quantum can be calculated using below formula
E=hv...........eqn(1)
But v=λ/ c .........eqn(2)
If we substitute eqn(2) into eqn(1) we have
E= hc/(λ)
Where E= energy
h= Plank's constant= 6.62607004 × 10-34 m2 kg / s
c= speed of light
c= 2.998 × 10^8 m/s
λ= wavelength= ?
But the energy was given in Kj , it must be converted to Kj/ photon for unit consistency.
Energy E= 272 kJ/mol × 1mol/6.02× 10^23
Energy= 451.83× 10^-24 Kj/ photon
E= hc/(λ)...........eqn(1)
If we make λ subject of the formula
λ= hc/E
Then substitute the values we have
λ= [(6.626 × 10^-34) × (2.998 × 10^8)]/451.83× 10^-24
λ=(0.00043965) × (1Kj/1000J) × (10^9nm/1m)
λ=439.7nm
Hence, the longest wavelength of radiation with enough energy to break carbon-sulfur bonds is 439.7nm
Answer:
The pH of the solution will be 7.53.
Explanation:
Dissociation constant of KClO=
Concentration of acid in 1 l= 0.30 M
Then in 200 ml = 
The concentration of acid, HClO=[acid]= 0.006 M
Concentration of salt in 1 L = 0.20 M
Then in 300 ml = 
The concentration of acid, KClO=[salt]= 0.006 M
The pH of the solution will be given by formula :
![pH=pK_{a}^o+\log\frac{[salt]}{[acid]}](https://tex.z-dn.net/?f=pH%3DpK_%7Ba%7D%5Eo%2B%5Clog%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D)
![pH=-\log[2.8\times 10^{-8}]+\frac{[0.06 M]}{[0.06 M]}](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B2.8%5Ctimes%2010%5E%7B-8%7D%5D%2B%5Cfrac%7B%5B0.06%20M%5D%7D%7B%5B0.06%20M%5D%7D)
The pH of the solution will be 7.53.
Answer:
Full answer in explanation
Explanation:
- High Tide - when tides are at their highest elevation
- Low Tide - when tides are at their lowest elevation
- Spring Tide - when tides experience the greatest range between high and low; occur at New and Full Moons
- Neap Tide - when tides experience the least range between high and low; occur at 1st and 3rd Quarter Moons
- Gravitational Pull - the invisible force that exists between all objects that have mass. The greater the mass, the greater the effect of the force
- Tide - the daily change in ocean levels due to the gravitational force of the moon and the sun exerted on Earth
Hope this helps!
Answer:
A (2.475 mol O2). B (11.35 g) C. (.4875 mol O2)
Explanation:
A.
convert 25.9 g C4H10 (68g/mol) to mol. --> .3808 mol
then use mole ratios from equation
.3808 mol C4H10 x (13 mol O2 / 2 mol C4H10). ---> 2.475 mol O2
B.
convert 22.2 g CO2 (44g/mol) to mol. ---> .5045 mol
.5045 mol CO2 x (10 mol H2O / 8 mol CO2) ----> .6306 mol H2O
convert .6306 mol to g ----> 11.35 g
C.
.3 mol CO2 x (13 mol O2 / 8 mol CO2) ---> .4875 mol O2
