When carbon an oxygen combine chemically, the mass of the product is....
2 answers:
Answer:The correct answer is option (2).
Explanation:
According to Law of Conservation of Mass , mass can neither be created nor be destroyed.
In a balanced chemical equation of reaction , the mass of the reactant is always equal to the mass of the products. As we can observe this law in the chemical reaction between carbon and oxygen.
Total mass of reactant = 12 g/mol + 32 g/mol = 44 g/mol
Total mass of products = (12 g/mol + 2 × (16 g/mol)) = 44 g/mol
Since,the law of conservation of mass is justified by the above reaction .Hence ,the correct answer is option (2).

Answer:
The simulated 1H NMR spectrum for ethyl acetate is shown in the drawing attached.
Explanation:
To construct this NMR it is necessary to identify the essential components that can produce resonance peaks.
Two main groups can be identified, the acetyl group containing a sub-component (CH3) capable of producing a resonance peak, and the ethyl group containing two components (CH2 and CH3) each of which can produce on its own its own resonance peak.
