Answer:
CH₂O
Explanation:
From the question given above, the following data were obtained:
Carbon (C) = 39.9%
Hydrogen (H) = 6.7%
Oxygen (O) = 53.4%
Empirical formula =?
The empirical formula of acetic acid can be obtained as follow:
C = 39.9%
H = 6.7%
O = 53.4%
Divide by their molar mass
C = 39.9 / 12 = 3.3
H = 6.7 / 1 = 6.7
O = 53.4 / 16 = 3.3
Divide by the smallest
C = 3.3 / 3.3 = 1
H = 6.7 / 3.3 = 2
O = 3.3 / 3.3 = 1
The empirical formula => CH₂O
Answer: has properties similar to other elements in group 18, does not react readily with other elements, is part of the noble gas group
Explanation: I’ve done on edg before
According to the report of US Environmental Protection
Agency, majority of large dose radiation exposure comes from natural background
radiation sources particularly the radioactive gases radon and thoron. This two
gases form when naturally occurring elements decay. However in the case of
man-made sources, the largest dose comes from medical x-rays.
