You’re running an experiment with fertilizer where you give fifteen plants (all the same type of plant) different amounts of fertilizer to study how effective the fertilizer is in different quantities. Match the following vocabulary words to the appropriate blank.
Independent variable, Dependent variable, Constant, Control
: Making sure that you expose the plants to the same amount of sun and water.
: How fast the plants grow.
: The fertilizer.
: A plant that is not given fertilizer at all.

Describe the interaction that occurs between two objects with the same electrical charge.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
