Explanation:

Reactant- a substance that takes part in and undergoes change during a reaction.

Product- a substance produced during a natural, chemical, or manufacturing process.

Precipitate- 1. to separate from a solution as a precipitate. 2. to fall to the earth's surface as a condensed form of water; to rain, snow, hail, drizzle, etc.

Precipitate has different meanings so I didn't really know about which one, but tell me if I'm wrong :)

Answer 2

Answer:

Reactant: a substance that takes part in and undergoes change during a reaction.

Product: are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state.

Precipitate: a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid

Scientists have discovered a colony of potential organisms on the Planet Moby and named them "Maxoids." Read the information below that scientists have gathered on Maxoids and decide whether Maxoids are living or nonliving things. Explain how you came to this conclusion.

Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.

Answers

The Maxoids are living things because they possess the characteristics of living things.

What happens to the atoms that make up hydrogen fuel as it burns?

Answers

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.

Explanation:

When hydrogen fuel burns, its atoms combine with oxygen atoms to form water molecules. So the atoms that make up hydrogen fuel become part of the water molecules.

A small gap is left between the rails in the railway track. Analyze the reason.

Answers

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.

Explain how the shape of a substance is determined by its state

Answers

I’m sorry I’m not very good at science but I’m pretty sure it’s…
A shape of a substance is determined by its state because when something is in a liquid state it fits the area of the object it is in. And when it is in gas form it doesn’t really fit in the object. When it is in solid form it may not fit in the object at all

Answer:

A solid will retain its shape; the particles are not free to move around. Liquid mattered. Liquid matter is made of more loosely packed particles. It will take the shape of its container . ... Gaseous matter is composed of particles packed so loosely that it has either a definded shape nor a defined volume.

True.
I’m at k12 student

Answer: True

Explanation:

Asteres planetoid, or 'wandering stars,' was the term used by Greek astronomers to describe star-like objects that appeared to move across the sky.

The term has been applied to a wide range of objects, including the moon, satellites, the sun, and asteroids.

A planet, according to the International Astronomical Union (IAU), is a body that orbits the Sun, is massive enough for its own gravity to keep it around, and has 'cleared its neighborhood' of smaller objects approaching its orbit.

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.

Answers

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

kinetic energy is given as

Scientists need to learn to make arguments based on evidence. That means they back up their statements

Answers

All complex life on Earth is eukaryotic. All eukaryotic cells share a common ancestor that arose just once in four billion years of evolution. Prokaryotes show no tendency to evolve greater morphological complexity, despite their metabolic virtuosity. Here I argue that the eukaryotic cell originated in a unique prokaryotic endosymbiosis, a singular event that transformed the selection pressures acting on both host and endosymbiont.

The combination of massive bioenergetic expansion, release from genome-size constraints, and high mutation rate favored a protosexual cell cycle and the accumulation of eukaryotic traits. These factors explain the unique origin of eukaryotes, the absence of true evolutionary intermediates, and the evolution of sex in eukaryotes but not prokaryotes.
