Steven Leung 9/19/06 Lab Report The Empirical Formula of a Copper Oxide Purpose: To convert an unknown copper oxide to copper (Cu) metal using natural gas to provide a reducing environment as shown below: Cu O (s) + CH (g) ¨ Cu (s) + Co (g) + H O (g) From the mass difference between the unknown copper oxide and the Cu metal generated at the completion of the reaction and the molar mass of Cu and oxygen‚ the empirical formula of the original copper oxide can be calculated.

Hebrew‚ practicing Judaism‚ and hiding in bomb shelters during World War II. This might explain why it’s been an ongoing process to figure out who I am and what’s really important to me‚ however over the last few years I have begun to understand my fluid identity. I consider myself a bit of a chameleon. I have a lot of interests‚ ranging from competitive tennis to orchestra to international community service.

Class: DME2 Title: Flow Measurement Date: 11/02/2013 Lecturer: Mr Higgins Summary: In this experiment many different meters were used to measure fluid flow rate; the orifice plate‚ the venture meter‚ the rota meter and the weigh tank. Each meter works by its ability to alter a certain physical property of the flowing fluid and then allows this alteration to be measured. The measured alterations are linked directly to the flow rate and these measurements are subbed in to adjusted equations

Breastfeeding vs. Formula Deciding whether to breastfeed or provide formula milk is a major decision amongst new mothers. As simple as it may seem‚ the decision to breastfeed versus formula feed babies can be difficult and one of the most important decisions a mother can make. While there is nothing wrong with giving babies formula milk‚ breastfeeding should be the number one choice for mothers. As breast milk provides more nutrients‚ is naturally produced by mothers and is less expensive

CHAPTER – 5 ANALYSIS OF HIGHER EDUCATION IN PAKISTAN There is no denying the fact that socio-economic development of any society mainly depends upon the quality and extent of education accessible to its members. Therefore its development is to be taken like a challenge‚ because prosperity and development of any society is linked with the significant and sustained investment in higher education.1 This challenge demands efficient and judicial use of available resources that may come from the
