Hydrogen

The images a MRI machine actually present are the water molecules that make up most of our bodies systems and organs. Water molecules consist of oxygen and hydrogen atoms, the core of which is a nucleus, a single proton. The protons have a basic property called nuclear spin as well as an electrical charge which makes them act like little magnets. When the magnetic field makes the spinning protons wiggle, the stronger the magnetic field, the faster the wiggle. Nuclei wiggle at roughly 50 million…

boiling point are all examples of physical properties (teacherlingo.com 1). Density is a physical property. Propane is denser than air, so when released it sinks to the floor. Carbon, one of the atoms in propane (c3h8), is often a black color, while hydrogen and oxygen do not have color. Propane is colorless and odorless when in its natural form, but odor is often added for commercial purposes. It has a molar mass of 44.0626 grams per…

ions. The importance of parentheses when used in chemical equations indicates that there are a certain number of atoms in a compound. An acis is a substance that gives off hydrogen ions in a aqueous solution while a base gives off -OH ions. There are only a few strong acid and bases most are weak meaning they produce few hydrogen ions in aqueous…

also different from group one as their reactivity decreases as you go down. Also, the elements becomes darker as you go down the group. Chemical reactions of group 1: The group 1 alkali metals are very reactive when put in water, as it produces hydrogen gas and alkaline solution (alkali metal hydroxide). The alkali metals reacts very fast and violent with water, as when you place the metals (lithium, sodium or potassium)…

aqcuainted with -- elemental hydrogen (H2) and elemental nitrogen (N2). The resulting product in this reaction is the covalent compound, ammonia (NH3). Elemental hydrogen and elemental nitrogen is something one should be familiar. Of course, elemental hydrogen is in the water humans drink everyday. However, hydrogen is quite rare elsewhere on Earth because it is nearly fourteen times lighter than the air in the atmosphere, so it rapidly escapes the Earth 's gravity if unbound. Hydrogen is the…

Experiment 1: Alkanes & alkenes: Combustion and action of sulphuric acid. Objective: To make careful observations and compare the difference(s) between alkanes and alkenes. Introduction: Hydrocarbons are composed exclusively of oxygen and hydrogen. There are three types of homogeneous hydrocarbons (whose members differ by one CH2 unit): alkanes, alkenes and alkynes. The difference between these three groups is in the bond types between the carbons. Alkanes form only single bonds, alkenes…

Alternative Fuels Argumentative Essay — Hydrogen Power If one lived in a house and did nothing but throw trash everywhere, it would be no surprise that the house is a mess. In a way, people around the world do similar actions yet deny the effects of pollution, such as global warming, more intense natural disasters and climate change. The analogy referent is people using and acquiring fossil fuels continuously and polluting the atmosphere while some people deny this act and others live in…

this property it contains hydrogen bonding as well as dipole-dipole forces, two of the strongest and most significant forces that affect the solubility of the solution. Each separate group has hydrogen’s bonded on to the group, so either the oxygen’s having…

Reaction #2- A few little bubbles when the Mg Dioxide combined with the Hydrogen peroxide. Reaction #3-A pop noise occurred appeared in the Test Tube with the combination of the Solid Zinc and Hydrochloric. Reaction #4-A gas substance came from the Test Tube with the mix of Copper (ll) Sulfate and Sodium Hydroxide. Conclusion:…

structure of perbromate is a tetrahedral. Although the structure contains 32 valence electrons, it obtains a total 1 single bond and 3 double bonds. The oxygens in the Lewis structure follow the octet rule however bromine does not. Bromine (besides hydrogen) does not follow the octet due to certain exceptions. Bromine can also found in the Earth’s crust. It is an acidic element and can be harmful and cause irritation if encountered. Bromine vapor, if exposed to, can be fatal even over a short…
