F = (mass)(acceleration) = ma
m = 55 kg
Vi = 20 m/s
t = 0.5 s
Vf = 0 m/s (since she was put to rest)
a=(Vf-Vi)/t
a=(0-20)/5
a = 40 m/s^2 (decelerating)
F = ma = (55 kg)(40 m/s^2)
F = 2200 N
Answer:
The multiring aromatic hydrocarbons in the coal liquid were hydrogenated to give saturated molecules that contained only one aromatic ring. Of the several organic bases investigated, potassium bis(trimethylsilyl)amide was found to be the most effective catalyst.

Answer:
The alkaline diet claims to help your body maintain its blood pH level. In fact, nothing you eat is going to substantially change the pH of your blood
Reaction: CS₂ + 3 O₂ → CO₂ + 2 SO₂
For every mole of CS₂, 3 moles of Oxygen formed.
So, Number of moles of CS₂ = 2.14/3 = 0.713 mol
Now, Number of moles = Given mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 76 * 0.713 [ Molar mass of CS₂ = 76 g/mol ]
Mass = 54.21 g
In short, Your Final Answer would be: 54.21 Grams
Hope this helps!
Answer:
A medida que aumenta la temperatura de un líquido, la solubilidad de los gases en ese líquido disminuye. Podemos usar la Segunda Ley de la Termodinámica para explicar por qué. Calentar una solución de un gas permite que las partículas de gas se muevan más libremente entre la solución y la fase gaseosa. La Segunda Ley predice que cambiarán al estado más desordenado, más altamente disperso y, por lo tanto, más probablemente gaseoso.
