Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments.
(a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized, and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight.
(b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u).
(c) Infrared spectroscopy showed that X contained one double bond.
(d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter.
(e) The aqueous solution of X is acidic.
What is the empirical formula of X?
(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true.
1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent.
In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant.
2. In a redox reaction, the reducing agent is oxidized and it gains electrons.
In a redox reaction, the oxidizing agent is reduced and it gains electrons.
3. Bending stress is also known as flexural stress.
The test used in observing the mechanical strength of chocolate is the three-point bend test.
4. The flexural strength of materials may be expressed in Pascals.
Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.
