Answer:
Explanation:
Hello,
In this case, for the given combustion process, we can compute the present moles of carbon atoms by considering that the only product containing carbon is CO2, thus, we have:
Next, we compute the moles of hydrogen that is present at the water only as a product:
Then, we compute the moles of oxygen by considering the oxygen present in both the CO2 and H2O and the initial sample:
Now, we divide the moles of C, H and O by the moles of O since they are lower amount, in order to compute the subscript in the empirical formula:
But the smallest whole number is:
Regards.
D. Experiments provided new evidence about the atom, I think, sorry if I’m wrong
First, determine the amount of vinegar in grams by multiplying the volume by the density. That is,
mass = (355 ml) x (1.01 g/mL) = 358.55 g
Then, multiply the calculated mass above by the decimal equivalent of the given percentage above.
amount of acetic acid = (358.55 g)(0.0602) = 21.58 g
Answer:
2NaOH(aq) + H2SO4(l) → 2H2O(l) + Na2SO4(aq)
Explanation:
2NaOH(aq) + H2SO4(l) → 2H2O(l) + Na2SO4(aq)
