The number of mole of carbon dioxide, CO₂ formed from the reaction is 0.0632 mole.

<h3>How to determine the mole of NaHCO₃</h3>
  • Molarity of NaHCO₃ = 2 M
  • Volume = 31.6 mL = 31.6 / 1000 = 0.0316 M
  • Mole of NaHCO₃ =?

Mole = Molarity x Volume

Mole of NaHCO₃ = 2 × 0.0316

Mole of NaHCO₃ = 0.0632 mole

<h3>How to determine the mole of CO₂</h3>

NaHCO₃ + HCl —> CO₂ + H₂O + NaCl

From the balanced equation above,

1 mole of NaHCO₃ reacted to produce 1 mole of CO₂.

Therefore,

0.0632 mole of NaHCO₃ will also react to produce 0.0632 mole of CO₂.

Thus, 0.0632 mole of CO₂ was obtained from the 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."

Drag the labels from the left to their correct locations in the concept map on the right. allele frequenices
mihalych1998 [28]

The labels are not found here but allele frequencies depend on the number of different gene variants in a given population.

<h3>What is an allele?</h3>

An allele is a given gene variant received from parents, which is found in a specific gene locus in a chromosome.

Allele frequency makes reference to the number of that a given gene variant or allele exhibits in a population or sample.

In conclusion, the labels are not found here but allele frequencies depend on the number of different gene variants in a given population.
