Molly Hubner Period 1 Extra Credit Paper Chemistry of Cancer Cancerous cells develop when conditions for cells are favorable‚ therefore following the divisions to continually occur‚ never stopping. When this happens‚ a tissue mass of cells called a tumor is formed and does not respond to normal controls regarding cell growth. Cancer cells have the following characteristics: profound changes in the plasma and membrane cytoplasm

Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending
