Answer:
40g
Explanation:
Solubility of Copper sulfate at 90°=60g
Solubility of potassium bromide at 90°=100g
100g-60g=40g
 
        
             
        
        
        
Answer:
Though the process photosynthesis
Explanation:
One of the important ways by which the atmosphere recycle gases through interactions with the the biosphere is by photosynthesis. 
The biosphere is the living component on the earth. The atmosphere is the gaseous envelope round the earth. 
- Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water in the presence of sunlight to produce glucose and oxygen gas. 
- This way, atmospheric carbon dioxide is exchanged for oxygen gas. 
This way, there is a sustained interaction between the atmosphere and biosphere. 
 
        
                    
             
        
        
        
To solve this problem it is necessary to apply the concepts related to the kinematic equations of movement description, which determine the velocity, such as the displacement of a particle as a function of time, that is to say

Where,
x = Displacement
v = Velocity
t = Time
Our values are given as,


Replacing we have that,



Therefore the distance from Earth to the Moon is 399.000 km
 
        
             
        
        
        
Green is reflected off of most plant leaves.
