Questions and Answers

1.

CO

Explanation
Carbon monoxide (CO) is a colorless and odorless gas that is formed from the incomplete combustion of carbon-containing substances. It is highly toxic and can be deadly when inhaled in high concentrations. Carbon monoxide is produced by vehicles, industrial processes, and the burning of fossil fuels. It binds to hemoglobin in the blood, reducing its ability to carry oxygen, leading to carbon monoxide poisoning. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, and confusion. It is important to have proper ventilation and carbon monoxide detectors in place to prevent exposure to this dangerous gas.

What is the Chemical Formula for Oxygen?
- A.
  
  O3
- B.
  
  H2SO4
- C.
  
  NaOH
- D.
  
  O2
Correct Answer
D. O2

Explanation
The chemical formula for oxygen is O2. This is because oxygen exists as a diatomic molecule, meaning it naturally occurs as a pair of oxygen atoms bonded together. The subscript "2" in the formula indicates the number of atoms present, in this case, two oxygen atoms. Therefore, O2 is the correct chemical formula for oxygen.

Is H2SO4 Calcium Carbonate?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
H2SO4 is the chemical formula for sulfuric acid, while calcium carbonate is the chemical compound found in limestone and marble. These two substances are completely different and do not have the same chemical composition. Therefore, H2SO4 is not calcium carbonate.

Is Glucose C6H12O6?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Glucose, with the chemical formula C6H12O6, is a simple sugar and the most common source of energy in living organisms. It is a monosaccharide and is commonly referred to as blood sugar. The molecular formula C6H12O6 indicates that glucose contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Therefore, the statement "Glucose C6H12O6" is true.

Ammonia
- A.
  
  NH3
- B.
  
  CO
- C.
  
  NaOH
- D.
  
  C12H22O11
Correct Answer
A. NH3

Explanation
NH3 is the correct answer because it is the chemical formula for ammonia. The other options listed (CO, NaOH, C12H22O11) do not represent ammonia.

What is the Chemical Formula for Water?
- A.
  
  NaCl
- B.
  
  NH3
- C.
  
  H2O
- D.
  
  NaOH
Correct Answer
C. H2O

Explanation
The chemical formula for water is H2O. This formula represents that water is composed of two hydrogen atoms bonded to one oxygen atom. The "H" represents hydrogen, and the "O" represents oxygen. The subscript "2" indicates that there are two hydrogen atoms present in the water molecule. This formula is widely recognized and accepted in the field of chemistry.

CO2
- A.
  
  Carbon Dioxide
- B.
  
  Sucrose
- C.
  
  Carbon Monoxide
- D.
  
  Calcium Carbonate
Correct Answer
A. Carbon Dioxide

Explanation
Carbon Dioxide is the correct answer because it is a compound composed of one carbon atom and two oxygen atoms. It is a colorless and odorless gas that is produced during respiration and combustion processes. Carbon Dioxide is a greenhouse gas that contributes to climate change and is also used in various industries such as food and beverage manufacturing, fire extinguishers, and carbonation of drinks.

What is the Chemical Formula for Sulfuric acid?

Correct Answer
H2SO4

Explanation
The chemical formula for sulfuric acid is H2SO4. This formula represents the composition of the acid, indicating that it contains two hydrogen (H) atoms, one sulfur (S) atom, and four oxygen (O) atoms. The subscript numbers indicate the number of each element present in the molecule. Sulfuric acid is a strong and highly corrosive acid commonly used in various industrial processes, such as in the production of fertilizers, dyes, and detergents.
