However, unpaid interns, when offered jobs because of their internship, fail to receive higher salaries as a result of their experience. Deciding between an internship and volunteer position requires careful study with a focus on your career goals. Experience gives you an insight into prospective job duties. Shadowing a professional at work allows a view of the career position, but many times the experience is an idealized view of the workday. Volunteering and internships offer a candid look at your prospective employer without the veneer of a guest experience.
Question: Calcium carbide reacts with water to produce acety... Calcium carbide reacts with water to produce acetylene gas, C2H2. CaC2 (s) + 2 H2O (l) ----> Ca(OH)2 (aq) + C2H2 (g) Calculate the volume (in liters) of acetylene produced at 29 degrees C and 684 mmHg from 0.026 mol CaC2 and excess H2O. ________________L.
This reaction was the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide. At high temperatures, CaC 2 reacts with water vapor to give calcium carbonate, carbon dioxide and hydrogen. Today acetylene is mainly manufactured by the partial combustion of methane or appears as a side product in the ethylene stream from cracking of hydrocarbons.
