Oxygen (O) Human beings obtain this element from the air. It enters a person’s bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells‚ oxygen combines with chemicals obtained from food. Energy produced during this process makes it possible for each cell to perform its function in the body. Also‚ oxygen atoms are present in water and water is essential to all life. It is present in many organic compounds. While oxygen is necessary for life‚ oxygen as ozone

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (Metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as Metubine‚ would interfere with muscle contraction. In order to understand how a neuromuscular blocking agent works one must first understand the process of muscle contraction and what has to take place in order for us

The objective of this lab was to. First‚ we measured out 2.00g of granular zinc and 2.03g of iodine crystals and added them together into a boiling tube‚ which we labeled "R". After‚ we added a boiling chip into a large test tube labeled "P" and we also labeled an empty regular sized test tube with a "C". When we added 5mL of acetic acid to tube R‚ the solution turned red and was hot. After we add 30 drops of the red solution into tube C and continued to swirl tube R‚ the solution became

EXPERIMENT 4 TITLE Complex Formation and Precipitation. INTRODUCTION Precipitation is the formation of a solid in a solution as the result of either a chemical reaction‚ or supersaturating a solution with a salt resulting in solid material collecting on the bottom of the beaker (Housecroft & Constable‚ 2006). When the solution has been supersaturated by a compound and no more material can be supported by the solution‚ it considered as precipitate. Commonly‚ the solid will fall out of the
