Tetrachloroethylene, C2Cl4, can be prepared by reacting acetylene (C2H2), chlorine and calcium hydroxide. The equation for the reaction is:

Tetrachloroethylene, C2Cl4, can be prepared by reacting acetylene (C2H2), chlorine and calcium hydroxide. The equation for the reaction is:C2H2 + Cl2 + Ca(OH)2 –> C2Cl4 + CaCl2 + H2Oassuming an excess of calcium hydroxide, how many moles of C2Cl4 can be obtained if 50.0 g of C2H2 and 115.0 g of Cl2 are used?

When nerve cells are at rest, there is an unequal amount of positive and negative charges on either side of a nerve cell membrane. This charge difference creates an electrical potential. Describe how the resting membrane potential (resting potential) is generated. Describe the role of sodium ions and sodium channels in generating an action potential.

When an automobile moves with constant speed down a highway, most of the power developed by the engine is used to compensate for the mechanical energy loss due to frictional forces exerted on the car by the air and the road. If the power developed by the engine is 181 hp, estimate the total friction […]
