Cellular Respiration
Because there are a number of enzymes and steps involved in forming porphyrin rings, there are a number of possible points in the process where genetic defects could occur. Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation (other types of fermentation such as methanol fermentation and acetone fermentation also exist)
DAVID POGUE: The military made only one uranium bomb, because separating rare U-235 from the more common U-238, which doesn't work in fission reactions, is a very difficult process. Dude, you just caught a shark with your bare hands! Then, flip the shark upside down, which induces a trance state called "tonic immobility." Once the shark is calm, we test its reaction to a piece of ordinary, non-magnetic lead
Contributions of force from different sources can be summed to give the net force at any given point.Any of the four natural phenomena involving the interaction between particles of matter. intellectual, social, political, or moral influence or strength: the force of his argument, the forces of evil a person or thing with such influence: he was a force in the land 6
Jiskha Homework Help - Search: Determine the ionization energy of a hydrogen atom
November 18, 2012 by smile Chemistry (Follow up post - Dr.BOB22) Ionization is when an electron is removed from an atom and ionization energy is the energy required to do this. November 16, 2012 by hi chem What are the similarities and differences between the hydrogen atom 2s and 3s orbitals? a) What are the similarities and differences between the hydrogen atom 2s and 3s orbitals? b) What are the similarities and differences between the 2s orbital and a 2p orbital? c) For the ..

Exercise 1: The structure of the atom Problem 1:Explain the meaning of each of the following terms: nucleus electron atomic mass Show me the answers Practise more questions like this Answer 1: a) Key points: protons, neutrons, nucleons, centre of atom. do not carry any extra charge, then the number of protons in an atom has to be the same as the number of electrons to balance out the positive and negative charge to zero
The Energy Story - Chapter 2: What Is Electricity?
The Latin word, electricus, means to "produce from amber by friction." So, we get our English word electricity from Greek and Latin words that were about amber. But what is electricity? Where does it come from? How does it work? Before we understand all that, we need to know a little bit about atoms and their structure
"Electricity" Misconceptions Spread By K-6 Textbooks
We find that it travels as wave energy, that it exists only outside of the wires, and most importantly, that it travels one way along both wires on its trip from the battery to the bulb. Or instead, if we place a voltage across a piece of metal or across a puddle of salt water, the charges present in those materials will flow, and an electric current will appear, since these substances are always full of movable charges, and therefore the "voltage pressure" causes their charges to flow
Silver Colloids: Definition of Terms
colloid stability - The interaction of particles in polar liquids is not governed by the electrical potential at the surface of the particle, but by the effective potential of the particle and its associated ions . Conductance is defined as the reciprocal of the resistance in ohms, measured between the opposing faces of a 1 cm cube of liquid at a specific temperature
Again, although both compounds are composed of the same types of atoms, they are chemically quite different: hydrogen peroxide is quite reactive and has been used as a rocket fuel (it powered Evil Kenievel part way over the Snake River canyon). Molecules and Ions Atoms, Molecules and Ions Molecules and ions Molecules and Ions Although atoms are the smallest unique unit of a particular element, in nature only the noble gases can be found as isolated atoms
Atom definition of Atom in the Free Online Encyclopedia
Atoms containing the same number of protons but different numbers of neutrons represent different forms, or isotopes isotope, in chemistry and physics, one of two or more atoms having the same atomic number but differing in atomic weight and mass number. In a complex atom these electrons are grouped in shells which encircle the nucleus at various distances and which are characterized by specific electron density distributions
Chemical Bond definition of Chemical Bond in the Free Online Encyclopedia
Moreover, if we assign to each carbon atom a tetrahedral structure, with bent bonds in the double-bond positions (a shared edge of two tetrahedrons), the prediction can be made that the benzene molecule is planar, with the carbon atoms at the corners of a regular hexagon and the hydrogen atoms at the corners of a larger coplanar regular hexagon. An example is Os4O4(CO)12, whose structure may be described as having the four osmium atoms at four alternating corners of a cube, with oxygen atoms at the other four corners
The Roman numerals at the top of the A families show the number of valence electrons (s and p electrons in the outermost energy level) in the particular element. In sodium chloride, a crystal is formed in which each sodium cation is surrounded by six different chloride anions, and each chloride anion is surrounded by six different sodium cations

27 SanmithaSep 3, 2012 @ 11:23 pmThanks a lot! I love Chemistry a lot now! I understand it better! 28 elleOct 19, 2013 @ 2:14 pmthanks! I'm in 5th grade and I was looking for something like this, because we have to write a 3 page essay on this, so this really helped! 29 sarahJun 4, 2014 @ 2:14 pmThank for this website it helped a lot, now i can master my science test( it's 35 questions!!!) 30 july katrinaAug 26, 2014 @ 8:08 amthank you so much for this website coz it really helps me :) 31 kassahun assenMar 14, 2015 @ 2:02 amthank you for this website coz it helped me to my education 32 RufaidahApr 21, 2015 @ 2:02 amI'm very glad to this website because its can help me to my chosen course. Thanks! 2 AmandaDec 5, 2008 @ 9:09 amThanks for all the help! Chemistry is getting very difficult and this is helping me get through our 6th chapter in the book
