Answer: The percent yield is, 42%
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
1 moles of 
require = 3 moles of 
Thus 0.020 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 2 moles of 
Thus 0.020 moles of give =
of
Theoretical mass of 
Actual mass of = 1.1 g
Now we have to calculate the percent yield
Therefore, the percent yield is, 42%
Show them a glass of water.
<span>tell them that the water is obviously in 3d because its not flat. Because this water takes up space in this glass it has a volume </span>
<span>Say anything that's 3d has a volume, even a 3d movie possibly. I know SPY KIDS 3 came out and some of the characters or things would jump off the screen. Since they aren't flat like a normal tv they have a volume</span>
Snow is precipitation in the form of ice crystals. It originates in clouds when temperatures are below the freezing point (0 degrees Celsius, or 32 degrees Fahrenheit), when water vapor in the atmosphere condenses directly into ice without going through the liquid stage.
Is the first one a true or false question?
Answer:
The correct answer will be option-about 174 base pairs of DNA are wrapped around an octamer of histone proteins.
Explanation:
A nucleosome is the fundamental unit of the chromatin thread polymer of DNA which is made up of a nucleosome core. The nucleosome core is composed of histone proteins H2A, H2B, H3, and H4 arranged in two copies forming an "octamer structure of proteins".
About 174 bp of DNA wraps around this nucleosome which is connected to other nucleosomes through 160 to 240 bp linker DNA.
Thus, the selected option is the correct answer.
