AnswerThe correct (A).
Explanation:
The true statement about the redox reaction is In a redox reaction, an electron is lost by the oxidizing agent.
Answer: The solution to the problem expressed to he correct number of significant figures is 1.69
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule applied for multiplication and division is :
The least precise number determines the number of significant figures in the answer.
As 12.0 has 3 significant digits and 7.11 also has 3 significant digits, the answer would also contain 3 significant digits.
For 
Thus the solution to the problem expressed to he correct number of significant figures is 1.69
The two carbon-sequestering methods that could reduce the impact of deforestation are afforestation and agriculture.
Carbon sequestering
- It is a process of capturing and storing the carbon dioxide gas of an atmosphere on a large scale.
- This is done to prevent adverse global climatic conditions
- The methods which can reduce the impact of deforestation are afforestation, wetlands, fertilizing ocean surfaces, agriculture, etc.
Afforestation
- Planting trees in the nonforest region or planting trees in the deforested region.
- By this more and more carbon dioxide gas will be absorbed by the tress from the atmosphere via photosynthesis and that will get involve in the carbon cycle.
- Help in re-establishing an ecosystem in the region and prevent soil erosion.
Agriculture
- Growing and planting crops which maintain carbon level of the soil, And along with absorbs carbon dioxide gas from the atmosphere.
- Will increase the concentration of oxygen gas in the atmosphere leading to prevent air pollution.
