Answers
Answer:
T.he structure of the earth is construed of a crust, the mantle, outer core, and the inner core. The shape of the earth is an oblate spheroid, because it is slightly flattened at the poles and bulging at the equator. Each layer has it's own chemical composition, and can impact Earth's surface.

Answers
Not every chemical reaction occurs in the same way. There are different types of chemical reactions, including synthesis reactions, decomposition reactions, and displacement reactions. In this experiment, a decomposition reaction takes place. During a decomposition reaction, a compound breaks apart into two or more products. Most decomposition reactions need an outside source of energy in order to take place.
Hydrogen peroxide is not a very stable compound, so it slowly decomposes into water and oxygen gas under normal conditions. In this reaction, yeast is used as a catalyst. A catalyst is a substance that helps to change the rate of a reaction. During the reaction, the catalyst is not consumed. As a result, the yeast makes the reaction occur much faster; it causes the hydrogen peroxide to break down and release the oxygen gas much faster.
The soap is used to help us “see” the reaction. Bubbles of oxygen become trapped in the soap, creating foam. The reaction occurs so quickly, releasing so much gas and creating so much foam, that the foam begins to flow out of the bottle. The result of this reaction looks like toothpaste being squeezed out of a tube.
In addition, the bottle will feel warm to the touch because the reaction is exothermic. An exothermic reaction or process is one that gives off energy. In contrast, an endothermic reaction or process is one that requires or absorbs energy.
HYPOTHESIS
uAdding yeast to hydrogen peroxide
will cause the hydrogen peroxide to
decompose quickly into water and oxygen gas, creating foam as the gas becomes trapped in liquid dish soap and pushes upward out of the bottle.
FORMULAS & EQUATIONS
Hydrogen peroxide is a relatively clear liquid substance. It is soluble in water and is often sold as a mixture of H2O2 in water. The hydrogen peroxide used in this experiment is actually a 6% solution of H2O2 in water.
The chemical formula for hydrogen peroxide is H2O2.
Hydrogen peroxide naturally decomposes into water and oxygen gas. The reaction is shown by the following equation:
2H2O2 (aq)g2H2O (l) + O2 (g)
The rate of the reaction can be increased by introducing a catalyst. In this experiment, the catalyst is yeast. Yeast is a microorganism that is part of the fungi family. Therefore, in the equation below, the catalyst is indicated above the arrow.

2H2O2 (aq) g 2H2O (l) + O2 (g)

3 When a kicker on the football team kicks a field goal, which forces are evident?
A The action of his foot striking the ball and the reaction of the ball against his foot.
B The mass of the ball being accelerated from rest by the kicker.
C Air friction slowing the ball as it is flying through the goal posts.
D All of these.
Answers
Answer:
The moment the ball leaves the foot, it stops accelerating, and from this point forward only two forces are exerted upon it: the friction with the air, which slows the ball's motion, and gravity, which pulls it down. As the ball moves, it slows and falls down.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

The three different heat transfer's shown while making of a smore are thermal energy transfer are convection, conduction and radiation.
What is thermal energy?Thermal energy is defined as the internal energy present in the system in a state to thermodynamic equilibrium by virtue of its temperature.
It can also be defined as the energy produced when rise in temperature causes atoms and molecules to move faster and colloid with each other.
Thermal energy are mainly of three types
Convection - When the heat transfer occurs due to actual motion of particles the process is known as convection. Conduction - When the heat transfer occurs due to vibration of subatomic particles in their mean position, the process is known as conduction,Radiation - When heat transfer occurs from one place to another by electromagnetic radiation the process is called as radiation.Thus, the three different heat transfer's shown while making of a smore are thermal energy transfer are convection, conduction and radiation.

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.

The area where the land meets the sea is called the coastline. This area can have different physical features depending on its location. Some common features of coastlines are beaches, cliffs, bays, harbors, estuaries, and dunes. Beaches are made up of loose particles like sand and gravel that are deposited by the sea.
In some areas, the shoreline may consist of a wide, sandy beach, while in others it may be rocky and steep.
In general, the shoreline is where the land transitions to the sea, and it is often marked by the presence of waves, tides, and other oceanic phenomena.
A group of students wants to investigate the effects of plant moisture on the growth of caterpillars. The students fill three identical boxes with an equal number of a kind of leaf that caterpillars eat. The students keep the leaves in the first box dry, spray the leaves in the second box with two sprays of water, and spray the leaves in the third box with four sprays of water. The students then add four caterpillars to each box. Every day, the length of the caterpillar is measured, recorded and the results are averaged. What is the tested (independent) variable in this experiment?
Answers
In the given experiment an independent variable is the growth of caterpillar.
What are variables?Variables are those quantities which will not have permanent value else they will have different values at different conditions.
Variables are also of two types:
Dependent variable: This variable changes its value according to the particular condition as in the given experiment leave is the dependent variable, because survival of leaf depends on moisture.Independent variable: This variable changes its value time to time but doesn't depend on any particular condition as in the given experiment caterpillar is the independent variable as their growth is not depend on any condition.Hence caterpillar is the independent variable.
