Study the flow chart below and answer the following questions that follow: 1. Identify reagent L. 2. Name the catalyst used in step iv. 3. Draw the structural formula of gas J.

Haya Agybeiber, twende na maswali haya ya kemia kutoka kwenye mchoro wa mtiririko:

1. Identify reagent L: Kutokana na mchoro, Gas J ni ethyne ($\text{C}_2\text{H}_2$). Ethyne huandaliwa kwa kawaida kutokana na mmenyuko wa Calcium Carbide na maji. Hivyo, reagent L ni Calcium Carbide ($\text{CaC}_2$).

2. Name the catalyst used in step V: Step V ni mmenyuko wa kubadilisha ethene ($\text{C}_2\text{H}_4$) kuwa ethanol ($\text{CH}_3\text{CH}_2\text{OH}$). Huu ni mmenyuko wa kuongeza maji (hydration) kwenye alkene. Kichocheo kinachotumika kwa mmenyuko huu ni asidi ya salfaiki iliyokolea (concentrated sulfuric acid, $\text{H}_2\text{SO}_4$).

3. Draw the structural formula of gas J: Gas J ni ethyne ($\text{C}_2\text{H}_2$). Ina kaboni mbili zilizounganishwa na kifungo mara tatu (triple bond), na kila kaboni imeunganishwa na hidrojeni moja. Muundo wake ni:

   $$\text{H-C}\equiv\text{C-H}$$
