I hope this helps! please tell me if it’s wrong.
Answer:
<u>49 moles of atoms</u>
Explanation:
There are 7 individual atoms in each molecule of H2SO4: (2 hydrogens + 1 sulfur + 4 oxygens).
Therefore, if 7 moles are decomposed, there would be 7 times that amount of individual atoms:
7 x 7 = 49 moles of atoms
All food chain in an ecosystem that are connected to each other forms a food web....
Therefore the answer is food web
Since you didn't give the actual volume (or any of the experimental values) I can only tell you how to do it. Do the calculation using the real (determined) volume of the flask. Then, re-do the calculation with v = 125ml. Take the two values and calculate % error; m = measured vol; g = guessed vol.
<span>[mW (m) - mW (g)]/mW (m) x 100% </span>
<span>(they want % error so, if it is negative, just get rid of the sign) </span>
