Answer:
Chemical properties can change due to a variety of things. If you were to talk about Weathering, the chemical properties change when there is acid rain, water, CO2, and O2. Chemical Properties change when the chemical properties of an object change too.
What is an ellipse please help)
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Maybe they might use that math thing for Science.
The corn crop in an area is prone to infestation by larvae from moths that feed on the cornstalks and ears of corn. The techniques used by two farmers to protect the corn crop are described below.
Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.
Which technique is likely to have less of an impact on the environment?
Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

Argon (Ar) is in group 18. Argon _____.
forms a salt when combined with a metal
has 18 electron shells
has properties similar to other elements in group 18
does not react readily with other elements
is part of the noble gas group
NEEDS TO BE ANSWERED ASAP
Argon (Ar) is in group 18. Argon is part of the noble gas group. Therefore, option D is correct.
What do you mean by noble gas ?The term noble gas is defined as any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. They are also called as inert gas element.
Noble gases, which are most commonly found as monatomic gases, have completely filled outer electron shells and thus have no desire to react with other elements, resulting in very few compounds.
Helium, neon, argon, krypton, xenon, and sometimes radon are examples of rare gases with high stability and extremely low reaction rates. Also known as inert gas.
Argon is called as noble gas element because they have completely filled their outermost shell.
Thus, option C is correct.

What kinds of changes happen to water as it goes through the water cycle? Are they physical or chemical?
Answer:
When water changes state in the water cycle, the total number of water particles remains the same. The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. All changes of state involve the transfer of energy.
Explanation:
and its physical
Answer:
The answer is Physical
Explanation:
The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. All changes of state involve the transfer of energy. They are all the same but no matter what state it's in it's still water so it's physical.
Why do physical properties change?
Answer:
Physical change takes place without any changes in molecular composition.

A small gap is left between the rails in the railway track. Analyze the reason.
Answer:
There could be several possible reasons for a small gap between rails on a railway track, such as:
1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.
2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.
3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.
4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.
These are some of the possible reasons for a small gap between the rails on a railway track.
Answer:
The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.
Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.
Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

What is true for two pieces of iron at the same temperature that are different mass?
A) The average kinetic energy of their particles is different.
B) Heat flows from the larger object to the smaller object.
C) The total thermal energy of their particles is different.
D) Heat flows from the smaller object to the larger object.
Answer:
Their particles have the same total kinetic energy.
Explanation:
Their particles have the same total kinetic energy.
C) The total thermal energy of the particles in each piece of iron will be different, because the total energy of a substance is proportional to its mass. However, if they are at the same temperature, their average thermal energy per particle will be the same.

What happened when the two substances were combined together in the cup? (highlight one)
The substances changed into different substances.
The substances did not change into different substances.
I am not sure if the substances changed into different substances.
Explain your answer using evidence from the Sim.
Based on evidence from Sim, when two substances were combined they did not change into different substances.
Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.
They just combine together and form a new substance.
Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.
The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.
Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.
If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.
It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.
