What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

What is thermal energy?Thermal energy is the energy associated with the random motion of particles in a substance. It is a form of kinetic energy created from the vibrational and rotational motion of atoms and molecules in a substance.
All objects contain thermal energy and when two objects of different temperatures are in contact, heat flows from the hotter object to the colder object until they reach a state of thermal equilibrium. Thermal energy is used in many applications such as heating, cooling, and even cooking food.

What is this natural process of particles (gases, liquids, and solids – when melted) going from a higher concentration to a lower concentration?
Answer:
This is by diffusion.
Explanation:
The slideshow describes what happens. Diffusion in liquids is slower than diffusion in gases because the particles in a liquid move more slowly. It happens faster if the temperature is increased

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s

During digestion, what happens in the stomach?
A. All food molecules are broken down into smaller molecules by chemical reactions.
B. Some types of food molecules are broken down into smaller molecules by chemical reactions.
C. Water in the food passes into the blood and travels to other organs where it is used.
D. Food passes into the blood and travels to other organs where it is used in various reactions.
Answer:
A
Explanation:
Food is digested in the stomach for several hours. During this time, a stomach enzyme called pepsin breaks down most of the protein in the food. The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones.

Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.
pls make it simple and not write a whole paragraph
Answer:
Explanation:
The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.
Answer:
the law of conservation of matter
Explanation:
The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.
The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.
C6H12O6 + 6O2 -> 6CO2 + 6H20
This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

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.
