2. An element is a substance that includes atoms. These atoms all have the same amount of protons.
3. A compound is formed when two or more separate elements combine and mix together. An example is pure table salt. Table salt is created by two elements which are sodium and chlorine. Sodium and chlorine combine and mix together until the end result which is the table salt.
4. Atoms are the units of life that are considered basic. Atoms relate to elements because elements consists of one specific kind of atom and the atoms are considered an element's base unit.
5. The components of an atom are very tiny particles called protons, neutrons …show more content…
A covalent chemical bond is a link that contains electrons which are shared between two atoms.
9. A polar bond is where the electrons forming the bond are not distributed equally between the two atoms of the bond. A nonpolar bond shares a pair of electrons with each other between two atoms of the bond. Water is polar because it has 18 electrons and it only holds 16 so there are 2 left which makes it unevenly distributed between hydrogen and oxygen.
10. An ion is a molecule or atom that gets either a negative or positive charge as a result of it losing or gaining one or more of its valence electrons. An ionic bond has an electrostatic force between oppositely charged ions in an ionic compound which affects the chemical link between two atoms. An ionic bond is formed when an electron is essentially transferred from one atom of a pair to the other creating ions. A sodium atom transfers an electron to a chlorine atom producing a sodium cation and a chloride anion and now are more energetically stable because they have complete valence shells. Sodium chloride exists as a crystal lattice with all the ions stacked in definite patterns. The ions are held together by electrostatic …show more content…
A chemical reaction produces a new substance and a different chemical identity from the interaction between two or more chemicals combining. The components of a chemical reaction include reactants and products.
CH4 (g) + 2O2(g)=> 2H2O(l) + CO2 (g)
13. Chemical equilibrium is the point at which the concentrations of products and reactants are in an unchanging ratio.
14. Specific heat is the amount of heat needed to increase the temperature by one degree Celsius. It is important because our planet has very large bodies of water. This helps because water can absorb and store heat which helps keep the temperature of our planet reasonable. From high specific heat, the water that covers most of Earth keeps temperature fluctuations on land and in water within limits that permit life.
15. Phases of matter for water include ice, liquid water and water vapor. Ice has the highest density, liquid water is the second highest and finally water vapor has the least density.
16. pH is the negative logarithm of the hydrogen ion concentration. pH is a measure of the hydrogen ion concentration of a solution. The pH scale measures how basic or acidic a substance is. Baking soda is neutral compound. Vinegar is an acid compound. Ammonia is a basic
