An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism.…
Dihydrogen Monoxide is a really dangerous chemical compound. Dihydrogen Monoxide is a colorless and odorless chemical compound also referred to by some as dihydrogen oxide. Dihydrogen Monoxide has many different hazards the main hazard is by accidental inhalation. Another hazard is severe burns, rust on many medals, it may cause electrical failures, and it has been found in excised tumors of terminal cancer patients.…

Johan Gottlieb Gahn, a swedish chemist, heated the mineral pyrolusite (MnO2) and in the presence of charcoal, found element 25, manganese in the year 1774. This silvery-metallic element has an atomic mass of 54.938049 rounded to 55 with 7 valence electrons. Manganese is a transition metal in group 7, period 4. Manganese is very flammable and dangerous with very strong intensity! It’s found in the earth’s mantle while having a melting point of 1246℉.…
Being able to lose weight without having to exercise a lot of time is something everybody would love to experience Fortunately, this seems to be possible. In accordance with a research made recently, compound 14, a synthesized molecule that tricks cells into thinking they have exercised rigorously has just been discovered. That actually means that researchers from the University of Southampton in The UK could soon create a functioning weight-loss pill. What Does Compound 14 Do?…
A little civilization ruled the northern coast of Peru from 1st to the 8th century CE, the people were called the Moche, also called Mochica (Cartwright, 2014). Each of the major Moche settlements seemed to have rulers who held religious and political power, the Moche's were not an Empire by more of independent societies ruled by common cultural features. They built huge and pyramids that are still here today, that now look eroded, so now they just look like natural hills. The pyramids that are known as 'huacas' that means sacred site contains collections of old cultures or the tombs of Moche leaders.…
The element boron, not to be confused with Borax or boric acid, is an essential trace mineral for human health, helping to strengthen bones, increase absorption of other minerals, and to regulate the sex hormones in both men and women. Intake of boron helps the body absorb and utilize other minerals by interacting with steroid hormones. Boron is important for bone growth and maintenance as it reduces the urinary excretion of magnesium and calcium. The boron vertebrate transporter helps these substances deposit within the bones rather than being excreted as waste. Higher levels of magnesium and calcium help prevent osteogenesis, or brittle bones (that can break easily,) which is especially important in postmenopausal women and older men, as a deficiency in these minerals has a negative effect on bone strength and regeneration.…
Using qualitative analysis, two cations in an unknown solution was identified. After repeated mixing, centrifugation, and decanting, lead was confirmed in Part A and barium in Part B. In Part C, different colored flames of metal species were observed using cation flame tests. Formula unit, total ionic, and net ionic equations were then composed for the identified cations. If the experiment were to be repeated, step 13 could be ommitted as barium was already confirmed in step 12 with the formation of yellow percipitate barium chromate, and calcium was not confirmed with step 14 when a white percipitate calcium oxalate was not present…

Amethyst- A treasurable stone consisting of a violet or purple variety of quartz. These gems were once believed to have magical qualities, and were supposed to contain the power to prevent or cure drunkenness to its wearer. This was perhaps believed to avoid drunkenness due to its wine-like color. People would wear rings made out of amethyst before or during drinking.…
The Noble Gas Equations By: Andy Jiang There is a pattern in the atomic numbers of Noble Gasses. The atomic of Noble Gasses aren't arbitrary or random. They have beautiful equations, which I have derived, that gives the atomic number of a Noble Gas based on what period it is in. Theoretically, my equations can work beyond the 7th period. The fact that there is an underlying pattern among the atomic number of Noble Gasses, something seemingly arbitrary, is a property of our mathematical, beautiful universe.…

If this experiment were to be repeated, another cation could be added for identification or a flame test could have been done with the solutions in Part A and Part B in order to determine the cation identity. In Part A of this experiment, after carefully following each procedure, lead was concluded to be the cation present in the #2 unknown aqueous solution. This was concluded because of the formation of a yellow powdery precipitate inside the solution during the sixth step. This was as expected.…
Ammonia is a compound composed of nitrogen and hydrogen, having the formula NH3. The ammonia molecule is formed by sp3 orbitals as it has a tetrahedral geometry and a trigonal pyramidal shape. Ammonia has an experimentally determined bond angle of 106.7°, and an a bond length of 101.7 pm. The nitrogen atom in the molecule has a lone electron pair, which gives the molecule a dipole moment and polarity. Ammonia’s lone electron pair makes NH3 a base, a proton acceptor, and gives it the ability to readily form bonds.…
This situation will lead to a ratio of too little oxygen because the magnesium burns too strongly in the covered crucible. Conclusion: The principle of the lab was to achieve the empirical formula of Magnesium Oxide by burning the Magnesium. After completing the procedures, the end result to be a form of magnesium powder, due to it being burned, yet in our experiment magnesium never actually got hot enough to ignite.…
