|---|---|---|---|---|---|
| what is polarity | polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multiple moment
🗑
|
||||
| what is cohesion | the sticking together of particles of the same substance
🗑
|
||||
| what is admission | the force of attraction that causes two different substances to join
🗑
|
||||
| what is universal solvent | water can desolate other substances
🗑
|
||||
| what is the chemical formula for water | H2O
there are 2 hydrogen molecules and 1 oxygen molecule. the bond is a hydrogen bond
🗑
|
||||
| what are the elements of carbohydrates | oxygen, hydrogen, carbon
monomer: glucose, fructose, molscarride
polymer: large molecule formed by smaller molecules stick together
E.G.: monasecharride
🗑
|
||||
| what are the elements in lipids | carbon, hydrogen, oxygen
monomer: any fatty substance or oils
polymer: saturated fatty acid there's saturated and unsaturated E.G. C57 H110 O6
🗑
|
||||
| what is the elements in proteins | carbon, hydrogen, nitrogen, sulfur ( sometimes)
monomer: DNA or RNA create proteins
polymer: peptide bonds
🗑
|
||||
| what is the elements of nucleic acids | oxygen, hydrogen, carbon, nitrogen, phosphorus
employer: nucleotides genetic code for all organisms
* phosphorus is what makes up DNA.
🗑
|
||||
| what is an electron | a electron is a negativity charged particle that orbit that nucleus of an atom
🗑
|
||||
| what is a proton | a proton is a positively charged particle that is inside the nucleus
🗑
|
||||
| what is a neutron | a neutron is a not positively or negativity charged but both. a neutron is also what makes but the nucleus of an atom.
🗑
|
||||
| what is a isotope | a isotope is different from a atomic # but is the same as the # of protons
🗑
|
||||
| what is a covalent bond | a covalent bond is when 2 atoms share an electron they are sharing it and they both get the electron.
🗑
|
||||
| what is a ionic bond | an ionic bond is when one atom gives one of its electrons away to another atom. the atom that gets the electron will become more negative the other more positive because its giving away one of its electrons.
🗑
|
||||
| what is a ion | an ion is the total # of electrons in an atom
🗑
|
||||
| what is cohesion | cohesion is when 2 molecules bond and form a new substance.
E.G. water
🗑
|
||||
| what is adhesion | adhesion is when particles cling to one another
🗑
|
||||
| what is dehydration synthesis | dehydration synthesis is when a chemical reaction that builds up molecules by water loss.
🗑
|
||||
| what is the range of basic pH | 8-14
🗑
|
||||
| what is the range of neutral pH | 7- pure
🗑
|
||||
| what is the range of acidic pH | 0-6
🗑
