That is true, the potential energy they possessed at the airplane door would be converted to kinetic energy. And if they driver is high up, he has further to fall. As the skydivers jump, the energy would be converted to kinetic energy.
A) mass of solute = 17 g
mass of solvent = 183 g
% = mass of solute / total x 100
% = 17 / ( 17 + 183 ) x 100
% = ( 17 / 200 ) x 100
% = 0.085 x 100
= 8.5 %
________________________________
b) mass of solute = 30.0 g
mass of solvent =300.0 g
% = mass of solute / total x 100
% = 30.0 / ( 30.0 + 300.0 ) x 100
% = (30.0 / 330.0 ) x 100
% = 0.090 x 100

Answer:
A. Nuclear
Explanation:
This is because it could cause severe environmental damage in areas inhabited by the public

Answer:
80C
Explanation:
As a substance gets hotter, or as a substance gets closer to the state of gas, the particles in the substance move faster, become more spread out and have more energy. This is why Gas has the most energy while solids have the least. Therefore, the hotter a substance is the more energy it has.
Answer:
9.82% of iron (II) will be sequestered by cyanide
Explanation:
We should first consider that Iron (II) and cyanide react to form the following structure:
[Fe(CN)₆]⁻⁴
Having considered this:
5.60 Lt Fe(II) 3.00x10⁻⁵ M ,this is, we have 5.60x3x10⁻⁵ = 1.68x10⁻⁴ moles of Fe⁺² (in 5.60 Lt)
Then , we have 9 ml NaCN 11.0 mM:
9 ml = 0.009 Lt
11.0 mM (milimolar) = 0.011 M (mol/lt)
So: 0.009x0.011 = 9.9x10⁻⁵ moles of CN⁻ ingested
As we now that the complex structure is formed by 1 Fe⁺² : 6 CN⁻ :
9.9x10⁻⁵ moles of CN⁻ will use 1.65x10⁻⁵ moles of Fe⁺² (this is, this amount of iron (II) will be sequestered
[(1.65x10⁻⁵ sequestred Fe⁺²)/(1.68x10⁻⁴ total available Fe⁺²)x100
% sequestered iron (II) = 9.82%
