What is the percent composition of hydrogen in vinegar (CH3COOH)?

barxatty [35]

Answer:

%H = 6.72 %

Explanation:

Percent composition of an element is the total mass of that element divided by the molecular mass of compound (or molecular mass) of which it is present in.

So,

Percent composition of Hydrogen will be given as,

%H = Total mass of H / Molecular Mass of Acetic Acid × 100

So,

Total Mass of H = 1.01 × 4 = 4.04 g

Molecular Mass of Acetic acid = 60.052 g/mol

Putting values in above formula,

%H = 4.04 g/mol ÷ 60.052 g/mol × 100

%H = 6.72 %

Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that

adelina 88 [10]

Answer:

The three-step synthesis of trans-2-pentene from acetylene is as follows.

Step -1: Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.

Step -2: Formation terminal alkyne to nonterminal alkynes.

Step -3: Formation of trans-pent - 2-pent-ene by reduction.

Explanation:

Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.

The chemical reaction of each step of chemical reactions is as follows.
