How does the development of the heliocentric model show how scientific ideas change over time?
Answer: Italian scientist Giordano Bruno was burned at the stake for teaching, among other heretical ideas, Copernicus' heliocentric view of the Universe. In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun.

What is Heliocentric model?Copernicus' heliocentric view of the Universe. In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun.
Because of heliocentrism, we now understand that Earth and the other planets of the solar system all orbit the sun.
But there once was a theory that put Earth at the centre of what was thought to be the entire cosmos and that everything literally revolved around us. The sun is at the centre of the heliocentric model, which is now known as the geocentric model.
Therefore, Italian scientist Giordano Bruno was burned at the stake for teaching, among other heretical ideas.

Answer: Below
Explanation:
Steal wool + oxygen (fire): The steel wool is a grayish color and has a rough surface. Oxygen is transparent It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder Well Iron oxide is 7 grams and steel wool combined is 7 grams so you can say that the mass was conserved Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide is cause because if a physical change.
Egg + Heat : The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white It was conserved because the eggshell was 4 grams and the fried egg is 41 grams It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.
Water + Heat The water is a clear liquid, while the heat is very hot but transparent The water turned into a type of oxygen -Water Vapor- If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor. There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition
Zinc + Hydrogen Chloride Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas. The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid. Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so you could say that the mass was conserved The production of a new substance (most probably hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left.
When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid.
Sodium Hydroxide + Copper Sulfate Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined make a total of 67 grams and the product is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but all together it is still 67 grams so you could say that the mass was conserved The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate.
A food scientist is determined to create a mango that looks exactly like a mango but tastes like salmon. Can this be achieved through artificial selection? Why or why not?
Answer:
depends on the artificial 'materials' used and the food scientist
Explanation:
If the food scientist is skilled enough and works hard enough this it might be possible but this does seem like a difficult task i personally doubt that this could be done until next few years. :)

Answer: C, the number of atoms stay the same
Explanation:
The number of atoms remains the same before and after the reaction. This is because of the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. In the case of methane burning, one molecule of methane (CH4) reacts with two molecules of oxygen (O2) to produce one molecule of carbon dioxide (CO2) and two molecules of water (H2O). The total number of atoms on both sides of the equation is conserved.

words from the video:
What do fireworks, a fried egg, and a rusting vehicle have in common? They all involve chemical reactions. If two or more elements or chemical compounds come into contact with one another and there is enough energy present, a chemical change may take place.
When a substance undergoes a chemical change, the chemical structure of that substance is altered. A chemical change can also be called a chemical reaction. During a chemical reaction a new substance is formed.
Observe the chemical reaction between bromine and aluminum. Pieces of aluminum are cut from a strip of foil and added to liquid bromine. At first there is no reaction because of the protective oxide coating on the aluminum. But soon an exothermic reaction between bromine and aluminum causes brown fumes of bromine to be given off. But as a new substance, aluminum bromide is produced. White smoke is produced.
The resulting residue is also aluminum bromide. When two compounds or molecules react together to form new substances, they are called reactants. They new substances created plus any resulting ash, water vapor, or carbon dioxide are called products, because they are produced by the reaction.
Some chemical reactions, such as the explosion of fireworks, can happen very fast—in less than a second.
Others, like the rusting of a car, might take years. It is important to carefully examine chemical reactions because there are many ways substances can be changed without a chemical reaction taking place.
Changes of state, for example, from a solid to a liquid or from a liquid to a gas, always involve a physical change rather than a chemical one. Melting sulfur is a good example. When solid sulfur is heated to 120 degrees Celsius it melts and first forms a pale yellow liquid.
In this form the atoms are covalently bonded and the liquid can flow easily. However, heated up beyond 150 degrees Celsius, the result is a dark red liquid that is over 2,000 times stickier. The sulfur may have changed physically but it's still sulfur.
No chemical reaction has taken place. Most of the time changes of state can be reversed by either adding or taking away heat. When water is boiled, for example, water vapor molecules are released in the process.
If you captured all the vapor molecules in a container they would reform again as water droplets once the vapor cooled. When a chemical change occurs it is more difficult to revert the substance back to its original state.
Answer:
this is answers to the second picture
Explanation:
1- energy
2- structure
3- reaction
4- substance
5- reactants
6- products
7- changed
8- At first there is no reaction because of the protective oxide coating on the aluminum. But soon an exothermic reaction between bromine and aluminum causes brown fumes of bromine to be given off. But as a new substance, aluminum bromide is produced. White smoke is produced.
9- heated to 120 degrees Celsius it melts and first forms a pale-yellow liquid.
In this form the atoms are covalently bonded, and the liquid can flow easily. However, heated up beyond 150 degrees Celsius, the result is a dark red
10- When a chemical change occurs it is more difficult to revert the substance back to its original state. (To be honest I don't know)
