<span>To find the percent yield, we first need to write this out as an equation:
3A + 2B --> C + 6D. The moles of C equals 1/3 times the moles of A. Therefore, the moles of C equals 4/3.
The theoretical yield equals = moles x molar mass of C.
(4/3) x (310.2) = 413.6g
The percent yield equals actual yield/theoretical yield x 100%.
382.5g/413.6g x 100% = 92.48%</span>
Answer
thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.
Answer:
How does an organisms DNA determine it's chances of survival:
Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers. If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population
How does humans manipulate DNA of organisms to be benefit themselves:
Biotechnology is the use of biological techniques and engineered organisms to make products or plants and animals that have desired traits.
Ans) 1.3 bison/mile
Soln:} See according to the question, Yellowstone National Park has an average of about 4500 bison living in it.
Area covered by Yellowstone park is 3472 miles.
So, to find the density of bisons living in Yellowstone Park we have to divide the no. of bisons by given area.
= 4500/3472
which is approximately 1.3 bisons per mile.
Therefore option a) is correct
Hope it helps!!!
