Answer:
hydrogen and cloride + hydrogen
The relationship between energy of a single photon and its wavelength can be determined using the formula E=hc/lambda where E is energy, h is Planck's constant, c is the speed of light, and lambda is photons.
Before being able to solve for energy, need to convert nanometers to meters.
407 nm (1 m/1 x 10^9 nm) = 4.07 x 10^-7 m
Then plug in the values we know into the equation.
E h(Planck's constant) c(speed of light)
E = (6.63 x 10^-34 Js)(3 x 10^8 m/s) / 4.07 x 10^-7 m (lambda)
E=(0.000000000000000000000000000000000663js)(300,000,000m/s)=1.989×10^-25j/ms
E=1.989x10^-25j/ms /{divided by} 4.07x10^-7m = 4.8869779x10^-33 J (the meters cancel out)
E = 4.89 x 10^-33 J
This gives us the energy in Joules of a single photon. Now, we can find the number of photons in 0.897 J
0.897J / 4.89 x 10^-33 J = ((0.897 J) / 4.89) x ((10^(-33)) J) = 1.8343558 x 10^-34
1.83435583 × 10-34m4 kg2 / s4 photons
Answer : The empirical formula is
.
Explanation :
Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.
Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.
The given molecular formula is
.
For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.
In the given formula, the valence is 1.
So, the empirical formula is
.
Answer:
From the water to the dry ice
Explanation:
The energy is transferred from the water to the dry ice because the water is warmer than the dry ice.
