COMBUSTION OF MAGNESIUM OXIDE DESIGN Aim/Purpose: To calculate the number of moles and the empirical formula of magnesium oxide. Safety precautions: 1) Wear lab coat 2) Wear gogles. 3)Make sure the bunsen burner is working properly and their is no leakage. 4) Wear gloves. Hypothesis: The weight of the magnesium ribbon increases after burning‚ so this indicated that their was a change in mass. This change happened because of the magnesium ribbon inside the crucible which reacted with Oxygen

Nitrous oxide Nitrous oxide Description Nitrous oxide — an odorless‚ tasteless gas — is an inhalation analgesia that can be used during labor. You administer the anesthetic gas using a hand-held face mask. Nitrous oxide takes effect within a minute. While common in the United Kingdom and Canada‚ this technique is rarely used in the United States. Pros Nitrous oxide alters pain perception. It can be used intermittently or continuously during labor. If you need to have a tear repaired after delivery

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods

The Copper A. In the text “the Copper” Glenn Gavin tells about his experience and viewpoints 20 months after he joined the Metropolitan Police. In the text are different subjects discussed. Glenn Gavin talks about his upraise inside the family and at school‚ the role of rules‚ his choice of carrier‚ and attitude toward politics. When Gavin was a kid his parents gave him a “guiding kick up the backside every now and then” (p. 1 l. 2). For example when he “came in late” (p. 1 l.3) or if he “was

Coursework 4 Copper Name of student: Alfiya Ospanova Tutorial group: G Copper is one of the earliest elements explored by humanity. Due to the special red shade it was easy to find in ancient times. The metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper).
