7. What can you infer about the climate of each region by reviewing these climographs?
> Tokyo is a place in between warm and cold with a good amount of precipitation. Trondheim is a warm place. Arica is a desert, so it is very humid there.
Research Question: Do Ocean Currents Influence Climate?
Hypothesis: Have each student discuss the research question with one or two other students and then write their hypothesis(es) on paper.
1st Procedure: Predicting the Effect of Ocean Surface Currents on Coastal Climates
Read the Introduction aloud. Then look at the map of major ocean currents and write a prediction describing the climate you would expect of each place listed below. (The symbols are to help locate the cities on the world map.)
Arica, Chile (along the Peru Current, symbol: star)
Trondheim, Norway (along the Norwegian Current, symbol: smiley face)
Tokyo, Japan (along the Kuroshio Current, symbol: heart)
2nd Procedure: Recording Data-Making a Climograph (teacher should make 3 copies of blank climographs per student or group.)
Using the climate data from Fact Sheet A, create a climograph for each city listed. Use a line graph for temperature and a bar graph for precipitation on the same graph.
Conclusion and Analysis:
1. Examine your climographs. What is the difference between the highest and lowest temperatures in the climograph for each city?
> Tokyo, Japan: 39 degree difference
Trondheim, Norway: 32 degree difference
Arica, Chile: 12 degree difference
2. Which city is a desert? How can you tell?
> Arica, Chile is the city in the desert. I know this because there is no precipitation.
3. Take a closer look at the Arica, Chile climograph. What can you tell about the seasons and the months? How is this related to the hemisphere where Arica is located?
> In Arica, it would be warmer during January, February, November, and December, but here during in the Northern Hemisphere it would be colder. The reason is because the seasons are reversed in the Southern and Northern Hemisphere.
4. Is there a relationship between the temperature of the ocean current and the coastal climate?
> Yes, the temperature of the ocean current and the costal climate do have a relationship. With warm currents, the air is warm and moist. With cold currents, the air is dry.
5. Is there a relationship between the direction of the ocean current and the coastal climate?
> Yes, the direction of the ocean current and the costal climate do have a relationship. The ocean currents from the coast affects how the air will be on
land.
6. In general, on which side of the ocean basins are the cold currents? Warm currents?
> The east side of the ocean basins is where the cold currents are. The west side of the ocean basins are where the warm currents are.

When a chemical reaction occurs, what happens to the atoms of the two substances? Provide an example from the Sim (on Amplify) as evidence to support your answer.
When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the given statement is true.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Cold, dry air against warm air creates a cold front, and visa versa warm air pushes against cold air its a warm front.
Therefore, the given statement is true.

B. Divide the atomic mass of fluorine by 6.
C. Subtract 6 from the atomic mass of fluorine.
D. Multiply the atomic mass of fluorine by 6.
Answers
Answer:
A
Explanation:
mole=mass of the element ÷ atomic mass of the element.
mole=6÷atomic mass of flourine.
The step at A correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine. That is "Divide 6 by the atomic mass of fluorine".
What is one mole of a substance?A mole is defined as the mass of the substance which consists of an equal quantity of basic units.One mole of any substance is equal to the value of 6.023 x \(10^2^3\) (Avagadro number). It can be used to measure the products obtained from the chemical reaction. The unit is denoted by mol.The formula for the number of moles formula is expressed as the number of moles of the substance = mass of the substance/ mass of one mole of the substanceHow to calculate the number of moles of fluorine equivalent to 6 grams of fluorine?Given that,
The mass of fluorine = 6 grams
The atomic mass of one mole of fluorine = 18.99
So, the number of moles of 6 grams of fluorine= \(\frac{6}{18.99}\)
Therefore, the step is given in option A: "Divide 6 by the atomic mass of fluorine" is the correct step that converts the 6 grams of fluorine to an equivalent number of moles of fluorine.

Describe how organisms in the tropical rainforest both depend on and compete for biotic and abiotic factors. In your answer, identify which factors are biotic and which are abiotic.
Answers
What are biotic and abiotic factors?
Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.) in an ecosystem. Therefore, both the abiotic and biotic resources affect the survival and reproduction process.
Answer:
Abiotic factors in the tropical rainforest include humidity, soil composition, temperature, and sunlight. A limiting factor in the ecosystem is that canopy layers block sunlight from reaching the forest floor, causing shorter plants to not be able to grow. Biotic factors in the tropical rainforest include orchids, lilies, heliconia, and bromeliads. Tropical rainforests can have various fungi, shrubs, herbs, woody vines, lichens, and mosses. The trees making up the rainforest canopy include the tonka bean wood, teak, rubber, and several species of evergreens and palm trees. This way the organisms in the tropical rainforest both depend on biotic and abiotic factors.

How to know how many electrons are involved in bonding of propane ?
Answers
In the bonding of propane (\(C_{3}H_{8}\)), there are 18 electrons involved.
You must count the electrons in propane's bonding using its Lewis structure. Propane (\(C_{3}H_{8}\)) has three carbon and eight hydrogen atoms.
How to calculate bonding electrons:
Count the molecule's valence electrons.
Three carbon atoms supply 12 valence electrons since carbon possesses four.
Eight hydrogen atoms contribute 8 valence electrons.
20 valence electrons: 12 (carbon) + 8 (hydrogen).
Single-bond atoms to form the molecule's skeleton.
Propane's skeleton is H-C-C-C-H.
To complete atom octets, distribute leftover electrons.
Start by bonding each carbon atom to the surrounding hydrogen atom with two electrons.
Distribute the remaining electrons to satisfy the carbon and hydrogen octet rule.
Count bonding electrons.
Each bond has two electrons—one from each bonding atom. Propane has nine C-H bonds, therefore bonding electrons total: 18 electrons from 9 C-H bonds.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
