Gold: Au
Potassium: K
Carbon: C
What is an atom made up of?
Protons, Neutrons and Electrons
if two Hydrogens Combine, how do you write the new chemical symbol?
Give 3 examples of Abiotic Factors?
Water, Temperature, Fire, Light, Soil type, Oxygen levels
How do Respiration and Photosynthesis relate?
What charge does an Anion and Cation have and why?
Anion = Negative because they gain an electron
Cation = Positive because they lose an electron
The number of protons can be determined by the?
Atomic Number
When two elements join. The metal name comes first and then the non-metal name. What suffix is used?
finish the example
Magnesium + Oxygen ->
...ide
-> Magnesium oxide
Give 3 Examples of Biotic Factors
Competition, Predation, Mutualism, Parasitism, Commensalism, Adaptations
How does Photosynthesis Generate energy?
Photosynthesis uses Sunlight to bond Carbon and Water to store energy in the form of Glucose.
What does the Law of Conservation of Mass state?
in a chemical reaction mass in neither created or destroyed. same mass of reactant and product.
How do you determine the number of neutrons in an atom?
Atomic Mass - number of Protons = Number of neutrons
When three or more elements combine and one of them is oxygen, what is the suffix?
Finish the example:
Copper + Sulphur + oxygen ->
...ate
-> Copper Sulfate
What are the three types of adaptations?
Structural, Behavioral and Functional
How does Respiration Produce Energy.
Respiration breaks carbon bonds and releases stored energy.
What do you change in a chemical reaction to balance it?
You change the Coefficient
How many electrons make up a valent shell
2 if it is the first shell and 8 for all others
What does a subscript show?
eg. H20 (2 is the subscript)
how many atoms of the element there are in a molecule
Define Predation.
When on organism kills and eats another, the attacker is called the predators and the one being eaten is called the prey.
Predation provides a food source for the predator.
Name the Consumers (including their order) and the Producers in this Food Chain.
Algae -> Shrimp -> Barramundi -> Shark
Producer - Algae
Primary Consumer - Shrimp
Secondary Consumer - Barramundi
Tertiary Consumer - Shark
Balance this equation:
Fe + o2 -> Fe203
4 Fe + 3 02 -> 2 Fe2O3
What is the Electron configuration of Carbon?
2, 4
What does a Coefficient show?
eg. 3 H20 (3 is the Coefficient)
how many molecules there are of a particular chemical
What did Charles Darwin Hypothesis with his theory of Survival of the Fittest.
he hypothesized that the organisms that can raise the largest number of offspring from birth to adulthood are the most successful. They show the best adaptations for survival in their particular habitat.
In a Food Web and Food chain the Primary, Secondary and Tertiary Consumers can also be grouped into three categories, what are they and what are their qualities?
Herbivore: Eats Producers (plants)
Carnivore: Eats Consumers (animals)
Omnivores: Eats Producers and Consumers (plants and animals)
