Answer:
yes and thanks for free points
A theory does not change into a scientific law with the accumulation of new or better evidence. A theory will always remain a theory
I believe that the delta h formation or enthalpy of
formation is only zero for pure elements. They are zero because they are the
most basic substances, that is you cannot form an element from an element.
Since Ozone is already a compound, a mixture of 2 oxygen O2 atoms, therefore
the δh∘<span>f is
not necessarily zero.</span>
Answer:
62.5 moles = 14008.7 in liters.
I hope this is helpful, have a great day.
Explanation:
Answer:
Explanation:
To convert from moles to grams, we must use the molar mass. This is found on the Periodic Table. Look for Phosphorous or P.
- Phosphorus (P): 30.973762 g/mol
We can use this number as a ratio.
Multiply by the given number of grams: 15.62
Flip the fraction so the grams of phosphorus cancel.
Divide.
The original measurement of grams has 4 significant figures, so our answer must have the same.
For the number we calculated, that is the ten thousandth place. The 9 in the hundredth thousandth place tells us to round the 2 to a 3.
There are 0.5043 moles of phosphorus in 15.62 grams.
