Hello everyone. The chemical that i’ve chosen to research is called “phthalate”, and the question I’m asking is whether it should be banned? The chemical formula for the most popular form of phthalate is C8H4O4. There is also a substance called “Phthalic acid”, from which phthalates originate, which is used to synthesize into phthalate. Some of phthalates physical properties include: a melting point of 207°, and a boiling point of 378°. It’s a colourless, white crystalline (translucent)…
Melissa Robell Ommidala Pattawong November 21st, 2014 Learning about Ammonia The chemical that I researched was Ammonia because of it’s involvement in agriculture. I am interested in agriculture and plan on majoring in Animal Science. Ammonia is an ingredient in many of the products that I use when working with animals and this made me curious. I used this opportunity to learn more about this chemical that is important in future career. Some general information about Ammonia is the chemical…
inorganic binary and polyatomic compounds derive their name? Well the cation metal is always named first with its name unchanged. The anion nonmetal is written after the cation to change the end in -ide. You're probably wondering what inorganic and organic compound are. An inorganic compound is any compound that is not organic while an organic compound is any member of large gaseous, liquid, or solid chemical compounds whose molecules contain carbon. A polyatomic ion compound are made up of two…
5861 What is the identity of the unknown hydrate? Hydrates are pure substances that contain water molecules embedded in their crystal structures. When a hydrate is heated the water molecules evaporate leaving behind a solid known as anhydrous. The identity of a hydrate can be found by finding out the percent water in the hydrate. The experiment was done in a manner to find the percent water in an unknown hydrate to identify the hydrate. The hydrates were BaCL2*2H2O, CuSO4*5H2O, CaCL2*2H2O, and…
Silver has an atomic mass of 107.9g whereas sodium has an atomic mass of 22.99g. The mass plays an important role in the value of chlorine because the mass precipitate value is used to determine the amount of chlorine moles in the precipitate. If the overall precipitate weighs less, there will be…
therefore do not conduct electricity well (645). Strong bases can dissociate completely into metal ions and hydroxide ions, while weak bases can only ionize partially (648). This means strong acids and bases are electrolytes. Electrolytes are ionic compounds whose aqueous solutions can conduct electricity…
3-triazole hybrids is demonstrated in Scheme 1. Compound 2 was prepared by treating propargyl bromide with 1H-indole-3-carbaldehyde (1) in presence of potassium carbonate in dry acetone at reflux temperature [26]. Compound 2 was further reacted by heating at reflux temperature with o-phenylenediamine (OPDA) in chloroform for 6 h afforded compound 3. Compound 3 coupled with variously substituted azides by Azide-Alkyne Cycloaddition reaction to afford title compounds 4a–j. The variously…
Seltzer/effervescent, Alcalak, and Medi-first were indirectly titrated with sodium hydroxide (NaOH), which is a strong base. By using the back titration technique, the amount…
Then, it was simply a matter of solving for the unknown metal and once we found how much the metal weighed, a quick glance at our periodic table identified the metal as sodium. The low percent error of 0.377% is indicative of the accuracy of this experiment. Possible sources of error include the unknown carbonate absorbing water during the heating and cooling process. There also may have been human error when the solid…
Arsenic exists in the environment in many different forms, each of those forms having different chemical abilities that have the potential to influence human health (Lynch, 2014). Arsenic has the potential to impact human health and has been studied over the centuries (Lynch, 2014). The research that has been studied has determined that the chemical form of arsenic found in food products characterizes over 20 different arsenic species (Lynch, 2014). The focus on organic and inorganic arsenic has…
