Arsenic has a melting point of 817.0 °C, and Its boiling point is 613.0 °C. Arsenic has a rhombohedral crystal structure, and it is usually found in a solid form while on earth. This element is found in group 15, p-block, on the periodic table, and Its period is period 4. Its electron configuration is [Ar] 4s2 3d10 4p3. B stands for beauty because, in The 1800’s arsenic was a huge beauty statement in Europe.
strained contains carbohydrates (4–5%), lactose (45–50 g/L), proteins (6–8 g/L), lipids (4–5 g/L) and mineral salts (8–10% of dried extract). Mineral salts include NaCl and KCl (>50%) as well as calcium salts (among others). The water content of cheese whey is quite high, constituting as much as 93.12 grams out of 100 g . When dewatered, however, solids are left. 2.2.7 Corn syrup.
Sulphur is a yellowish, non-metallic chemical element in the periodic table. It is found in group 6 and period 3. Sulphur is identified by the letter S. Since Sulphur is the 16th Element of the periodic table therefore atomic number is always similar as the proton number which is located in the nucleus and converts the nucleus in to a positive charge as neutron is a neutral charge (+-) so positive (+) plus neutral (+-) equals a positive charge. The atomic mass for sulphur is 32 amu or (Atomic Mass Unit is the international system of units).
Paraffins are one out of the three major classes of mineral oil hydrocarbons. Hydrocarbons and polar water molecules do not mix and because the hydrocarbons are not as dense as water, they just float on top of it. The light at the bottom of the lava lamp warms the hydrocarbon causing it to expand and
The inner core is about 759 miles in radius and is composed of iron and nickel metals. The average temperature of the inner core is 9,800 degrees Fahrenheit. The outer core is 1,400 miles thick and is made of iron and nickel fluids. The mantle is the thickest layer. Is composed of a hot, viscous mixture of molten rock that measures 1,800 miles thick.
g mass of magnesium oxide=0.25 mass of magnesium oxide - mass of Mg + mass of O 0.25g= 0.122g + mass of O mass of O = 0.25g- 0.122g = 0.128g moles of Mg = 0.122g x 1 mol of Mg divided 24.30g Mg ( mass of magnesium) = 0.122 mol Mg moles of O = 0.25 g O x 1 mol of O divided by 16g of O = 0.25 mol o the ratio = 1:1 there is one mol for mg for one mol of O, therefore there will be 1 atom of mg for 1 mol of oxygen. therefore the empirical formula of magnesium oxide is MgO. Conclusion: the main purpose of this experiment is to determine the reaction and the magnesium oxide’s empirical formula which is when magnesium reacts with oxygen in the air.
For ascorbate peroxidase assay extraction 241 buffer was supplemented with 1.0 mM ascorbic acid. The homogenate was centrifuged at 242 15,000×g for 15 min at 40C, and the supernatant was used as a crude enzyme extract. 243 Spectrophotometric determinations were performed using UV visible spectrophotometer 244 (UV-1700, Shimadju, Japan). 245 2.11.2. Estimation of superoxide dismutase (SOD) activity 246 SOD activity was estimated by its ability to catalyse NBT to formazan at 560nm 247 according to the method of Beyer and Fridovich (40).
The Statue of Liberty is a prime example of oxidized copper. The oxidized surface consists of insoluble ionic compounds of copper (II) oxide and copper (II) carbonate. In class, we did an experiment with where we changed copper into its different states. For example, we added sodium hydroxide to copper (II) nitrate. We turned the copper into a
By: Andrew Barton Periodic Table of Elements The periodic table was created in 1869 by Dmitri Mendeleev. He developed the table to illustrate the trends in properties of then known elements. The periodic tables purpose is to summarize the properties of real elements.
Every element has to have a family, right!!! Bromines family happens to be group 17 (VIIA) Halogen. And for this specific element the melting poi for Bromine is 19.04°F -7.2°C, and of course there 's a boiling point, which is 137.8°F
Zinc I 'm here to tell you about an element. It 's an element called zinc and can be found on the periodic table if you want to look it up. It was discovered in 1746 in Germany by a man named Andreas Marggraf. There is evidence that it was used back in ancient time to make brass weapons, armor, and shields. This atom contains 30 protons and 30 electrons.
