Ow does the weight of the water displaced compare to the buoyant force?
Ghella [55]

Answer: They are the same.

Expatiation:

Buoyant force: An upward thrust exerted by any fluid on an object placed in it.

According to Archimedes' principle which states that 'upward thrust exerted by the fluid on an object immersed in a fluid whether partially or fully is equal to the weight of the fluid displaced by the immersed body'.This force  acts in the upward direction at the center of mass of the displaced fluid.

Hence, it is correct to say that weight of the water displaced compare to the buoyant force are the same.

Be sure to answer all parts. Nitric oxide, NO·, is a radical thought to cause ozone destruction by a mechanism similar to that o
SIZIF [17.4K]

Answer:

See image attached and explanation

Explanation:

The stratospheric ozone layer is very important in absorbing high-energy ultraviolet radiation that is harmful to living systems on earth. The concentration of ozone in the stratosphere is determined by both thermal and photochemical pathways for its decomposition. Nitric oxide, NO, is a trace constituent in the stratosphere that reacts with ozone to form nitrogen dioxide, NO2, and the diatomic oxygen molecule. The nitrogen-oxygen bond in NO2 is relatively weak. When an NO2 molecule encounters an oxygen atom, it transfers an oxygen, forming O2 and NO. The chemical reactions involved are formations of NO2 following by reaction of NO2 with atomic oxygen for form NO and O2. The sum of both reactions show that the overall reaction is simply the reaction of ozone with atomic oxygen to form two molecules of molecular oxygen. Hence, NO only serves as a catalyst, it does not undergo a permanent change itself.

Can yall answer the question on the image PLEASE
Brut [27]
Answer is 67.8%

To find the percent yield the equation is actual yield over theoretical yield, and multiply by 100. In this problem it is 4.06996 / 6 = 0.678 x 100 = 67.8%
