Chm 130 lab 7

Determine the simplest whole number ratio of moles of zinc used, to moles of chlorine reacted in the zinc chloride that was produced. In another experiment, a lab student analyzes a sample of a compound containing Question 2 of 33 3. This would give the formula a zero charge, and also make it an ionic compound. List at. Follow-Up Questions Show all work for calculations. To learn about the common techniques and laboratory equipment used to make SI measurents. Thus when zinc and chlorine combine, it actually takes 2 chlorine ions to bond with 1 zinc ion. To do this, you know that the zinc and the hydrochloric acid combined to create zinc chloride. Also in the lab there is less distractions as children and pets are not allowed in. Labs are set up with safety in mind, they have eye wash stations, and the proper equipment to ensure everyone safety. Gather the metric ruler, CD or….

Bag A contains A. Calculate moles of chlorine reacted based on your answer for 2. The difference between these two masses is the mass of zinc chlorine produced. Calculate moles of zinc based on original mass of zinc.

This also presents a danger to people working at home with kids and animals nearby.

Determine the simplest whole number ratio of moles of zinc used, to moles of chlorine reacted in the zinc chloride that was produced. In a lab all the same type of equipment is used.

You know the original mass of the beaker. The second reason this lab could not be done at home is, if it was attempted at home by using other items such as a stove as a substitute hot plate, accuracy would then be affected. The second element the non-metal is named by adding —ide to the end of it, providing it is a monatomic ion. The purpose of this lab is to compare these four different kinds of fish by comparing their protein by protein profiling. This is a very dangerous experiment, the glass could break, the chlorine could spill and get on your skin, or in your eyes. Calculate moles of chlorine reacted based on your answer for 2. Items like this are available in laboratory settings, so it is better to do this lab in an actual laboratory. The difference between these two masses is the mass of zinc chlorine produced. If samples of DNA are cut using certain restriction….

Creative learning is about helping children develop imaginative thinking through exploration…. Is zinc chloride an ionic compound or a molecular compound?
