How does evolution work

1 answer:

4 0

Billions of years ago, according to the theory of evolution, chemicals randomly organized themselves into a self-replicating molecule. This spark of life was the seed of every living thing we see today (as well as those we no longer see, like dinosaurs). That simplest life form, through the processes of mutation and natural selection, has been shaped into every living species on the planet.

How do solve for density?

Pachacha [2.7K]

Density(D) is defined as Mass(M) divided by Volume(V).

The formula for Density is:

D = M / V.

Another way to remember the formula for Density is to remember "Mass per unit of volume".

I hope this helps!

Answer:

212.304 grams

Explanation:

similar to your other question, use the same formula

q=mCpΔT

23617=m(4.182)(46.6-20)

23617=111.2412m

m=212.304g

The theoretical yield of ammonia in an industrial synthesis was 550 kg, but only 480 kg was obtained. What was the percentage yi

Klio2033 [76]

We know that when calculating percent yield, we use the equation:

$Percent yield=\frac{Actual yield (A)}{Theoretical yield (T)}$

Since the quantities that we are given in the question are equal, we can just directly divide them to find percent yield:

$Percentyield=\frac{480kg}{550kg} =0.8727*100=87.27$

So now we know that the percent yield of the synthesis is 87.27%.
