Company with Charles Chipman’s Sons Company. In 1979‚ CU had to narrow down its product lines to increase profit margins by removing production inefficiencies. By 1980 it primarily manufactured men’s and boy’s casual and athletic socks‚ which were sold to the retail/ distribution channels unbranded as private label merchandise. By early 1980‚ CU’s market share was estimated at 10% of units and 11% of factory sales. The distribution channel of CU was also wide spread. In 1979‚ over 90% of its production

Introduction Women were considered sub-sets of their husbands‚ and after marriage they did not have the right to own property‚ maintain their wages‚ or sign a contract‚ much less vote. It was expected that women be obedient wives‚ never to hold a thought or opinion independent of their husbands. It was considered improper for women to travel alone or to speak in public. In this paper the author will present the trace of the rise‚ the key players‚ the division within the movement‚ and what

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

dropped into a test-tube with 0.5 M hydrochloric acid. Results: The reaction formulas of the metals and the ions are as following: Zn(s)+2H+(aq)->Zn2+ + H2 Zn(s)+Pb2+(aq)->Zn2+ +Pb Zn(s)+Cu2+(aq)->Zn2+ +Cu Zn(s)+2Ag+(aq)->Zn2+ +2Ag Pb(s)+Cu2+(aq)->Pb2+ +Cu Pb(s)+2Ag+(aq)->Pb2+ +Ag Cu(s)+2Ag+(aq)->Cu2+ +2Ag Conclusions: Zinc is the strongest reducing agent. Zinc loses electrons most easily and is therefore oxidised. After zinc comes lead‚ followed by copper‚ while silver has least reducing
