Answer:
Explanation:
given reaction
2O₃ ⇄ 3O₂
initial 1 1
final 1-x 1+ 1.5x
rate of reaction = k [ O₃ ]² / [ O₂ ]
initial rate = k . 1² / 1 = k
final rate = k (1-x )² / (1+ 1.5x) = k/2
(1-x )² / (1+ 1.5x) = 1/2
2x² - 5.5 x + 1 = 0
x = 0.196
So fraction of ozone reacted = .196
Answer:
Here the force is 10N and the mass is 5 kg. Dividing both sides by 5kg, we get a = 2 m/s^2.
Answer:
Fluid Friction
Explanation:
Fluid friction involves a fluid or air. The air resistance on an airplane or water resistance on a boat is fluid friction. Rolling Friction - Rolling friction occurs when a round surface rolls over a surface, like a ball or wheel.
The chemical reaction of magnesium and sodium hydroxide would yield magnesium hydroxide and sodium. The chemical reaction is expressed as:
Mg(s)+ 2NaOH(aq)→Mg(OH)2(s)+2Na
In ionic form,
Mg(s) + 2Na+ + 2OH−(aq)→Mg(OH)2(s) + 2Na
Answer:
Chromatography
Explanation:
Chromatography is a technique for separating mixtures that involves the use of a moving liquid and filter paper. The solvent travels through the spots on the paper, taking the chemicals away in the opposite direction. If the solvent combination has been properly chosen, each of them will move at a different velocity than the others.
