Answer:

According to my own knowledge, I would say that the difference between a star and a comet is that the star is a thing that is like the sun, but a comet is something that Moves around the sun and travels.

I would say that the major differences are that stars are fixed points in the sky, while comets orbit the sun elliptically, and that stars are made of gas, whereas comets are made of ice and dust.

What is the denominator of the simplified expression? 2 n
Shtirlitz [24]

The expression \frac{2n}{6n + 4} * \frac{3n + 2}{3n - 2} is a product expression

The denominator of the simplified fraction is 3n -2

<h3>How to determine the denominator?</h3>

The expression is given as;

\frac{2n}{6n + 4} * \frac{3n + 2}{3n - 2}

Divide the first fraction by 2/2

\frac{n}{3n + 2} * \frac{3n + 2}{3n - 2}\\

Evaluate the above product

\frac{n}{3n - 2}

The above fraction is a simplified fraction of \frac{2n}{6n + 4} * \frac{3n + 2}{3n - 2}, and the denominator is 3n - 2

Hence, the denominator of the simplified fraction is 3n -2

vitfil [10]

In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium   when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.

<h3>What occurs if a reaction reaches dynamic equilibrium in a closed system?</h3>

A closed chemical system is said to attain dynamic equilibrium if the rate of the forward reaction is said to have equals the rate of the backward reaction and also the level of concentrations of products and reactants are said to be the same.

Hence, In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium   when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.

1. What is geothermal energy?

D. It is the heat coming from the Earth’s interior.

2. In which areas could you find geothermal power plant?

Near hot steam reservoirs. So, C. near volcanoes.

3. What could be the structure of the volcanoes which serves as the source of geothermal energy?  

B. Magma Chamber? I am unsure.  

4. Which of the following is NOT involved in the geothermal plant system? *  

 D. Wood

"Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity."

5. Why is the Philippines considered as one of the world’s top producer of geothermal energy?  

D. The Philippines lies along the Pacific Ring of Fire.

"The Philippines is one of the world's top producers of geothermal power, owing to its location along the Ring of Fire zone of Pacific volcanoes."

6. What will happen to hot water in a geothermal power plant?  

A. It will turn into steam.

"Hot water is pumped from deep underground through a well under high pressure. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam. The steam spins a turbine, which is connected to a generator that produces electricity."

8. How does geothermal energy affect the environment negatively?

"The main environmental concern that comes with geothermal power plants is the potential for surface instability. Because geothermal plants remove water and steam from reservoirs within the earth, the land above those reservoirs can sometimes sink slowly over time."

9. What makes geothermal energy environmental friendly?  

A. It is a renewable source of energy

 

10. Which of the following places in the Philippines can produce geothermal energy? *  

D. Tiwi, Albay

"Philippine geothermal resources are spread among 7 specific regions: Leyte, MakBan, Tiwi, South Negros, BacMan, Mindanao, and the Northern Negros."
