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.
First, they must start with various raw materials that make up the monomers. Ethylene and propylene, for example, come from crude oil, which contains the hydrocarbons that make up the monomers. The hydrocarbon raw materials are obtained from the cracking process used in refining oil and natural gas (see How Oil Refining Works). Once various hydrocarbons are obtained from cracking, they are chemically processed to make hydrocarbon monomers and other carbon monomers (like styrene, vinyl chloride, acrylonitrile) used in plastics.
