Answer:
C2H6 + 7/2O2 ....... 2CO2 + 3H2O
Answer:
c. 1.4 x 10²³ oxygen atoms
Explanation:
The number of oxygen atoms in one molecule of CH₃COOH is 2.
Avogadro's constant relates the number of molecules in one mole:
6.022 × 10²³ mol⁻¹
Thus, the number of oxygen atoms in one molecule of acetic acid can be converted to the number of oxygen atoms in one mole of acetic acid:
(2 oxygen atoms / molecule)(6.022 × 10²³ molecule / mol) = 1.204 x 10²⁴ atoms per mole
Finally, the number of oxygen atoms in 0.12 moles of acetic acid are calculated:
(1.204 x 10²⁴ atoms / mol)(0.12 mol) = 1.4 x 10²³ atoms/mol
Answer:
Why does this happen?
can the motion of these celestial bodies help in telling time?
does this have something to do with the earth's axis?
They use experimental investigations where they manipulate variables
Answer:
1 only
Explanation:
a compound is a mix of two different elements, two of the same element is just a molecule
