Answer is: the energy of exactly one photon of this light is 4.75·10⁻¹⁹ J.
Photon energy equation: E = h·ν.
E - energy of one photon.
ν- frequency.
h - Planck's constant.
ν = 7.17·10¹⁴ Hz.
h = 6.63·10⁻³⁴ J·s.
E = 6.63·10⁻³⁴ J·s · 7.17·10¹⁴ Hz.
E = 4.75·10⁻¹⁹ J.
Answer:
Lithium fluoride i think but I am not really sure
But it should be Lithium fluoride
Explanation: that's because neighter boron nor nitrogen contains water
Since it goes to completion, we can use:
Use NaMaVa =NbMbVb
where
Na= moles of H+ in H2SO4
Ma= molarity of the acid
Va= volume of the acid
Nb= moles of OH- in NaOH
Mb= molarity of the base
Vb= molarity of the base
plug in the numbers
(2 moles of H+) (Volume acid) (10.00mL acid) = (1 mole of OH-) (.248M base) (18.71mL base)
20 V = 4.64
V= .232 M
Answer:
Regional metamorphism occurs at convergent plate boundaries, due to intense pressure. As two plates collide, the Earth's crust folds and faults. The intense pressure changes large areas of the Earth's crust into metamorphic rock. Mountain ranges are typically metamorphic rock, due to plate tectonic processes.
