Answer:
Molarity =  0.7 M
Explanation:
Given data:
Volume of KCl = 20 mL ( 0.02 L)
Molarity = 3.5 M
Final volume = 100 mL (0.1 L)
Molarity in 100 mL = ?
Solution:
Molarity = number of moles of solute / volume in litter.
First of all we will determine the number of moles of KCl available.
Number of moles = molarity × volume in litter
Number of moles = 3.5 M × 0.02 L
Number of moles = 0.07 mol
Molarity in 100 mL.
Molarity = number of moles / volume in litter
Molarity =  0.07 mol /0.1 L
Molarity =  0.7 M

</h3>
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  
Usually radioactive elements have an unstable atomic nucleus.  
General formulas used in decay:  

T = duration of decay  
t 1/2 = half-life  
N₀ = the number of initial radioactive atoms  
Nt = the number of radioactive atoms left after decaying during T time  
Nt=25 g
No=100 g
t1/2=5770 years

 
        
             
        
        
        
Answer:
The sun radiates energy in all directions. 
Explanation:
Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans
