Answer: The correct statement is: Atoms lose smaller particles during radioactive decay.
Explanation:
Radioactive decay is a process where unstable atomic nuclei lose energy by emitting radiation in the form of particles or electromagnetic waves. As a result of this process, the unstable atoms transform into a different element or isotope. During the decay, the atoms lose smaller particles such as alpha particles, beta particles, or gamma rays. This loss of particles changes the number of protons and neutrons in the nucleus, which leads to the formation of a new element.
statement describes what is gained or lost during radioactive decay: atoms lose smaller particles. That is the third option, as during radioactive decay, the nucleus of an atom can lose subatomic particles, such as alpha or beta particles, which results in the transformation of the original atom into a new atom or a different isotope of the same element.

My Question: How do the number of atoms at the start of a chemical reaction compare to the number of atoms at the end of the reaction? (HINT: Use the Law of Conservation of Mass)
-Please answer in 2-4 sentences.
Explanation:
As it is a fact that "The law of conservation of matter(mass) says that matter cannot be created or destroyed". In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the
products.
Answer:
Explanation:
According to the Law of Conservation of Mass, the number of atoms at the start of a chemical reaction is equal to the number of atoms at the end of the reaction. This is because, in a chemical reaction, the total mass of the reactants must be equal to the total mass of the products. Thus, while the way atoms are bonded together may change, the number of atoms of each element remains constant.
the total number of atoms of each element before and after the reaction remains the same. This is because atoms cannot be created or destroyed in a chemical reaction, they can only be rearranged

Coat the surface of the water with a sorbent material.
Wait until the water calms down and then install booms to contain the spill.
Answer:Install booms made from, or with, sorbent materials around the oil spill.
Explanation:Dispersants and booms and skimmers are the most frequently used methods to clean up ocean oil spills. All methods have advantages and disadvantages. The effectiveness depends on the situation – the amount and type of oil, the ocean currents and tides and the weather.
A plant makes glucose during photosynthesis. Glucose consists of the elements carbon, hydrogen, and oxygen. What is the source of the elements for the glucose that the plant makes? Construct an explanation.
Answer:
The source of the elements that make up glucose in a plant is primarily carbon dioxide (CO2) from the air, water (H2O) from the soil through the roots, and energy from sunlight.
During photosynthesis, chlorophyll in the plant's leaves absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen. This process involves a series of complex chemical reactions, collectively called the Calvin cycle, that occur within specialized structures in plant cells called chloroplasts.
In the first stage of the Calvin cycle, carbon dioxide molecules in the air are captured by an enzyme called rubisco and combined with a molecule called ribulose bisphosphate (RuBP). This results in the formation of an unstable molecule that quickly breaks down into two molecules of a three-carbon compound called 3-phosphoglycerate (3PG).
Next, the energy from sunlight is used to convert the 3PG molecules into a different three-carbon compound called glyceraldehyde 3-phosphate (G3P). Some of the G3P molecules are used to make glucose, while others are used to regenerate the original RuBP molecule that can be used in the next cycle.
Finally, the glucose molecules are transported throughout the plant and used as a source of energy for cellular respiration, which releases the stored energy in the glucose molecules to power various cellular processes in the plant. The oxygen produced during photosynthesis is released into the air as a byproduct of the process.
In summary, the source of the elements for the glucose that the plant makes is carbon dioxide from the air, water from the soil, and energy from sunlight.

A water molecule takes a journey that includes a cloud, mountain, atmosphere, lake, and groundwater. Write a scientific explanation about the directions the water molecule would move and what causes it to move through the cycle. (Must use CER!) (Finish it immediately!)
Answer:
Claim: A water molecule moves through the water cycle in a continuous journey that involves changes in state and location.
Evidence: The journey of a water molecule begins when it evaporates from a body of water, such as a lake or the ocean, due to the energy from the sun. The water molecule rises into the atmosphere and joins other water molecules to form a cloud. As the cloud moves, it may pass over a mountain and cool, causing the water molecules to condense into liquid or solid form and fall as precipitation. Some of the precipitation may fall into a lake or river, where it can flow downstream and eventually enter the groundwater system. The water in the groundwater system may eventually resurface in a lake or river, or it may be extracted from a well for human use.
Reasoning: The movement of a water molecule through the water cycle is driven by a combination of physical and chemical processes, including evaporation, condensation, precipitation, and infiltration. The sun provides the energy that drives the cycle, causing water to evaporate and rise into the atmosphere. As the water molecules cool, they may condense into clouds and eventually fall as precipitation. The movement of water through the cycle is also influenced by factors such as temperature, pressure, and gravity. For example, water will flow downhill due to gravity, which can cause it to move through the groundwater system and eventually resurface in a lake or river. Overall, the water cycle is a complex and continuous journey that is essential for maintaining the Earth's water supply and supporting life.

Write a scientific argument that addresses the question: Which suspect is most likely to have made the hydrofluoric acid? First, state your claim. Then, use evidence to support your claim. For each piece of evidence you use, explain how the evidence supports your claim.
THE SUSPECTS ARE EITHER PAT OR TRACY. I'm pretty sure it's Pat but I need a clear explanation to why it is her who created the hydrofluoric acid!
Answer:
Pat is most likely to have made the hydrofluoric acid. My first piece of evidence is that the chemical supply company delivered sulfuric acid and calcium fluoride to Pat’s house However, these substances were not found at Pat’s house. This could mean that Pat used these substances in a chemical reaction. This evidence supports my claim because a chemical reaction between sulfuric acid and calcium fluoride could cause the atoms to rearrange to form hydrofluoric acid as one of the products. This is because sulfuric acid contains hydrogen atoms, and calcium fluoride contains fluorine atoms, which are the two types of atoms that repeat to make up hydrofluoric acid.
My next piece of evidence is that the police found calcium sulfate at Pat’s house. This evidence supports my claim because if Pat mixed the sulfuric acid and the calcium fluoride to make hydrofluoric acid, then the other product of this reaction could be calcium sulfate. This is because only the hydrogen and fluorine atoms would rearrange to form hydrofluoric acid. The rest of the atoms of the reactants would have to rearrange to form another substance. Calcium sulfate is probably the other product that would form because its atom group contains all the atoms that did not rearrange to form hydrofluoric acid. This evidence suggests that Pat mixed sulfuric acid and calcium fluoride to make the hydro.. whatever.

What does a seismograph record?
A. the distance from the epicenter of an earthquake
B. the vibrations produced by an earthquake
C. the amount of damage that results from an earthquake
D. the total amount of energy released by an earthquake
1. Magnitude measures the energy released by the earthquake, while intensity measures its duration. The correct option is A.
2. The conclusion you can draw between the two conditions is that there is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location and is denoted as option A.
3. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
4. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.
