<span>Oxidation is the loss of electrons and corresponds to an increase in oxidation state. A reduction is the gain of electrons and corresponds to a decrease in oxidation state. Balancing redox reactions can be more complicated than balancing other types of reactions because both the mass and charge must be balanced. Redox reactions occurring in aqueous solutions can be balanced by using a special procedure called the half-reaction method of balancing. In this procedure, the overall equation is broken down into two half-reactions: one for oxidation and the other for reduction. The half-reactions are balanced individually and then added together so that the number of electrons generated in the oxidation half-reaction is the same as the number of electrons consumed in the reduction half-reaction.</span>
Definition: Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.
Types:
Budding- A form of asexual reproduction of yeast in which a new cell grows out of the body of a parent.
Vegetative Reproduction- Plants budding which creates a runner hich sends a clone
Strawberries plants
Dandelion
Parthenogenesis- An unfertilized egg develops into an adult (Aphids, honeybees, lizards)
Binary Fission- One cell splits into two cells
Allows for no genetic variety
Bacteria performs it
Protests perform it but takes longer
Regeneration- The ability to regrow a missing part of the body by Mitosis
Fragmentation- A small piece of an organism breaks away from it and develops into a new individual (star fish)
Spores- Contain DNA, cytoplasm, and tough putter wall protects it from dying out produced by many organisms (algae, fungi, bacteria)
Advantages: Allows rapid populating, does not need mates, does not require mobility, friendly to the environment, handy in case of emergency.
Disadvantage: poses some inheritance issues, can lead organism to being prude to extinction, carries problems with population control, causes organism to not be able to adapt and results in poor conditions to subject
Valence.
The electrons in the outer shell of an atom are called valence electrons.
Valence electrons determine whether the an element is ready form compounds. These electrons can be gained, lost, or shared in the formation of compounds.
The compound crystallizes in the aluminium trifluoride motif. Each fluoride is a doubly bridging ligand. The cobalt centers are octahedral.
CoF3 decomposes upon contact with water to give oxygen:
4 CoF3 + 2 H2O → 4 HF + 4 CoF2 + O2
It reacts with fluoride salts to give the anion [CoF6]3−, which is also features high-spin, octahedral cobalt(III) center.
You take the grams of CO₂ times Avogadro's number divided by the molar mass.
