Hey there!:
Given, energy, E = 703 kJ/mol
λ = ?
We need to do conversion of kJ/mol to J
So, E = 703 kJ/mol*1000 J*kJ *1 mole / 6.023*10²³
= 1.17*10-18 J
We know formula,
E = h*C/ λ
So, λ = h*C / E
= ( 6.626*10-34 J.s ) * ( 3.0*10⁸ m.s⁻¹ ) / ( 1.17*10⁻¹⁸ J )
= 1.70*10⁻⁷ m
So, 1 m = 1*10⁹ nm
So, 1.70*10⁻⁷ m = ?
= 170 nm
Hope that helps!
I think it is Sedimentary rock, igneous is from fire/lava metamorphic is magma, so Sedimentary
Answer:
Synthesis reaction
Explanation:
This is a synthesis reaction. When you combine sodium metal (Na) with chlorine gas (Cl), you form sodium chloride or kosher salt (NaCl).
