Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

In class we made salt crystals. To do this we put a supersaturated solution of salt into a glass of water. After a few days the water evaporated and the salt crystals were left on the paper cutouts. When the salt dissolved in the water was this a physical change or a chemical reaction? Please explain your answer in detail.
Answer:
Dissolving a solid in liquid, such as table salt in water, is a physical change.
Explanation: Its a physical change because only the state of the matter has changed
Procedure and Data (20 points)
1. Remove the label from a 2- or 3-liter plastic soft drink bottle and wash the bottle. Be sure to rinse it very well so that no soap residue remains. Let the bottle dry.
2. Use a marker to draw a line around the bottle, about one-third of the way up from the bottom.
3. Use scissors to cut along the line you drew on the bottle. To start the cut, poke a hole in the bottle at some point on the line.
4. Place about 2 inches of gravel or pebbles in the bottom of the bottle. This layer will be a place for excess water to collect. It will keep the soil from getting too wet. (Optional: If you want your terrarium to last longer, sprinkle some activated charcoal and moss on top of the gravel or pebbles.)
5. Fill the remaining space in the bottom of the bottle with moist potting soil or dirt. Gently press down on the soil with a gloved hand until the surface of the soil is about 1 inch below the rim.
6. Add plants to the terrarium.
a. If you are using seeds, use your pinkie finger to make 8 to 10 small depressions in the soil. They should be about 0.5 inches deep. Place 1 or 2 seeds in each hole and cover them with soil.
b. If you are using live plants, remove 2 or 3 small plants from their containers. Be sure to keep the root ball intact. Plant them in the soil.
7. Pour tap water onto the soil so that it is moist but not completely soaked. Just a little bit of water should pass through to the pebbles. You should use less than 1 cup of water.
8. Put the bottle back together by sliding the top part onto the bottom part. Keep the top on the outside. You may need to squeeze the rim of the bottom section so the top section will fit around it.
9. Place the cap on the terrarium if it is not on already. Your setup should look like this if you started with young plants:
10. Describe your terrarium, including what you put in it and where those materials came from. Attach a photo or draw a diagram of your terrarium. Add labels to identify the important parts. (8 points)
11. Place your terrarium next to a window where it will receive plenty of natural sunlight. Do not place the terrarium outdoors. Observe the terrarium. If you planted seeds, wait until they sprout to begin recording what you see. If you start with live plants, you can begin recording your observations the next day. Make observations for four days in a row. Look at the terrarium first thing in the morning and at the same time each afternoon. Take note of where water can be observed. Look at how much water is in the pebbles and on the sides at the top of the terrarium. Record your data in the table below. (8 points)
Data Table for Observations in Bright Light

3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.

Chemical Weathering Rocks are changed by chemical and physical weathering. During chemical weathering, the composition of the rock is changed. Extreme heat and pressure within Earth can also cause rocks to change chemically. Physical weathering is the breaking down of rock by wind, water, ice, temperature change, and plants. It changes the shape and size of rocks, but it does not change their properties.
circle each example of chemical weathering
•Shale is worn into small pieces by the wind.
• Sandstone experiences heat and pressure and becomes quartzite.
• Calcium carbonate dissolves.
• Rocks break into pieces as they tumble down a mountain.
An example of chemical weathering are;
Sandstone experiences heat and pressure and becomes quartzite. Calcium carbonate dissolves.What is Chemical Weathering ?Chemical Weathering can be described as the type of weathering that do take place due to the breaking down of the rock particles into smaller pieces which is usually as a result of chemical process.
It should be noted that when the process is taking place it scould be due to the Extreme heat and pressure which can affect the composition of the particles and as a result of this there could be formation of products from the break 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
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.

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.
