I need help please on these questions, i can not do the model, so please help me, if you could give me an example that would be great 1. Which of the stages of the water cycle were you able to observe in your model?

2. What is the energy source in your model and what does it represent?

3. Did you observe evapotranspiration in your model? If yes, where? If no, how
could you have demonstrated it?

4. Where in your model does condensation occur more rapidly? How do you know?

5. Do you think your model accurately demonstrates the water cycle? Why or why
not? If you were to redesign your model, how would you refine it?
5 point for each.

Answers

Answer 1

Answer: 1. What were you able to observe
2. What runs the whole thing
3. Not to sure...maybe someone will have a better answer for you sorry!
4. Where does a vapor or gas turn into a liquid
5. Do you think that the model you did demonstrates a water cycle? And if you were to redo it, how would you redo it and demonstrate it!

Please helpRadiocontrast dyes are considered safe because the isotopes have short half-lives and the isotopes coat the gastrointestinal tract and are not absorbed by normal tissue. If a patient ingests 10.0 mg of iodine, how long until the iodine-134 is 99% out of the patient's system if the half-life of iodine-134 is 52.6 minutes?

Answers

In 52.6 mins the 10 mg of iodine will be divided by its half-life which is 2 it will become 5 mg (in 52.6 minutes ) and same procedure will be followed until it reach 99% out of the patient's system.

The answer is 368 minutes will it takes the iodine to be absorbed in one's system.

A or C becuase i heard if you leave it to charge over night it'll explode

over heating can cause explosion of the hoverboards. To avoide these explosions, the companies which r making these hovard boards must put a cooling system in it.

In a single displacement reaction between sodium phosphate and barium, how much of each product (in grams) will be formed from 10.0 grams of barium?

Answers

Answer:

A. 3.36g of Na.

B. 14.62g of Ba3(PO4)2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3Ba + 2Na3PO4 → 6Na + Ba3(PO4)2

Next, we shall determine the mass of Ba that reacted and the mass of Na and Ba3(PO4)2 produced from the equation.

This is illustrated below:

Molar Mass of Ba = 137g/mol

Mass of Ba from the balanced equation = 3 x 137 = 411g

Molar mass of Na = 23g/mol

Mass of Na from the balanced equation = 6 x 23 = 138g

Molar mass of Ba3(PO4)2 = (3 x 137) + 2[31 + (4x16)] = 411 + 2[31 + 64] = 601g/mol

Mass of Ba3(PO4)2 from the balanced equation = 1 x 601 = 601g

Summary:

From the balanced equation above,

411g of Ba reacted to produce 138g of Na and 601g of Ba3(PO4)2.

A. Determination of the mass of Na produced by reacting 10g of Ba.

From the balanced equation above,

411g of Ba reacted to produce 138g of Na.

Therefore, 10g of Ba will react to produce = (10 x 138)/411 = 3.36g of Na.

Therefore, 3.36g of Na is produced.

B. Determination of the mass of Ba3(PO4)2 produced by reacting 10g of Ba.

From the balanced equation above,

411g of Ba reacted to produce 601g of Ba3(PO4)2.

Therefore, 10g of Ba will react to produce = (10 x 601)/411 = 14.62g of Ba3(PO4)2.

Therefore, 14.62g of Ba3(PO4)2 is produced.

Suppose the filament in a super-powerful flashlight is heated up to 3600 K. What type of light would be given off by this filament, mostly?

Answers

Answer:

The correct answer is "Infrared light".

Explanation:

Infrared light, also known as infrared radiation, is a type of light that can no be seen but it can be felt from the heat that it generates. The spectrum of wavelengths that comprise the infrared light is given from 700 nanometers, which is the edge of visible red light, up to 1 millimeter of wavelength. Near-Infrared light is the one that can reach the highest temperature, reaching from 3000 to 5200 K. Therefore, a super-powerful flashlight heated up to 3600 K can be given off infrared light.

How does the absorption and release of energy affect temperature change during a chemical reaction?

Answers

It depends. If you are talking about the temperature of the chemicals in the reaction, than the temperature increases due to increasing enthalpy. However, if you are talking about the temperature of the surrounding, than the temperature of the surrounding would actually decrease since heat is being taken away from the environment into the reaction.

if heat is absorbed, the temperature increases but if heat is released, the temperature decreases :))
