Answer

A, C

Explanation

Identify the methods that can provide information about the composition of nitroglycerin.
Evaluate each option:
- A. Combustion analysis: This method is useful for determining the empirical formula of a compound by analyzing the products of combustion. It can provide information about the amounts of carbon, hydrogen, and nitrogen in nitroglycerin. (Useful)
- B. A microscope: While a microscope can provide visual information about the structure of a substance, it does not provide information about the chemical composition or formula. (Not useful)
- C. A mass spectrometer: This instrument can determine the molecular weight and the structure of molecules, which is crucial for determining the chemical formula of nitroglycerin. (Useful)
- D. A bathroom scale: This can measure mass but does not provide specific information about the chemical composition or formula of a compound. (Not useful)
- E. A cathode ray tube: This is primarily used in physics experiments and does not provide information relevant to determining chemical formulas. (Not useful)
- F. A ruler: This can measure dimensions but does not provide any chemical information about the composition of a substance. (Not useful)
Compile the useful methods identified.
- Useful methods: A (combustion analysis) and C (mass spectrometer)

1 2 3 Consider the reaction shown below, in which 2-propanol is converted to acetone. square ° H_2C=frac ∈ t 0.4 ∈ t _HdH_2 H_3C-C- CH_3 1st attempt See Periodic Table Q See Hint In this reaction, focus on the carbon atom bonded to the OH group in the reactant. During this reaction, the C-O single bond is replaced by C=O double bond. O is electronegative than carbon, and we can say that electrons the carbon atom and the oxygen atom.
