Hi!
First of all, the melting of ice cream is not a chemical reaction, because there is no change in the components of the ice cream and if you freeze the ice cream again, you will get the same ice cream that you had previously.
The melting of ice cream is an example of a physical change, in which a substance goes from solid to liquid state, and it is an endothermic physical change.
When you freeze ice cream, the heat is removed from the ice cream, making it an exothermic process, when heat is liberated to the environment and it's taken away from the substance, in this case, the ice cream.
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.

Answer:
The final volume of the balloon is = 28.11 L
Explanation:
Initial pressure 
= 1.03 atm = 104.325 K pa
Initial temperature 
= 26 °c = 299 K
Initial volume 
= 22.4 L
Final temperature 
= 22 °c = 295 K
Final pressure 
= 0.81 atm = 82 K pa
We know that
Put all the values in above formula we get
= 28.11 L
This is the final volume of the balloon.
Answer:
The elements in same period have same principle quantum number or energy shell.
The elements in same group shows similar chemical and properties.
Explanation:
Inn group:
The elements in same group i.e present in vertical column shows similar chemical properties.
The elements in same group having same number of valance electrons. while in chemical reaction bonds are break and formed and valance electrons are involved. That's why elements in same group having same number of valance electrons and shows similar chemical properties.
In period:
While as we move from left to right the number of valance electron increase by one in every element. But the electron is added in same shell which means that their physical and chemical properties are different but principal quantum number is same.
