<span>The correct answer is option 1. Entropy is the degree of disorderliness in a system. Among the phases, solid has the most ordered structure. Also, at lower temperatures the molecules will have less kinetic energy therefore less motion. Thus, bromine in solid form at 266K has the least entropy.</span>
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!
The answer is All of them
B, a physical change because it is not destroying the substance.
An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.
