0.012moldm⁻³
Explanation:
Given parameters: 
Mass of AgNO₃  = 1000mg 
Volume of water = 500mL 
Unknown: 
Molarity of solution  = ? 
Solution: 
The molarity of a solution is the number of moles of a solute dissolved in volume of solvent. 
  Molarity = 
  
Number of moles of AgNO₃  = ? 
    Number of moles = 
Molar mass of AgNO₃ = 108 + 14 + 3(16) = 170g/mol
    convert mass to g; 
       1000mg = 1g 
  Number of moles  =  = 0.00588moles
  = 0.00588moles 
    convert the given volume to dm³; 
        1000mL  = 1dm³; 
         500mL = 0.5dm³
Now solve; 
   Molarity =  = 0.012moldm⁻³
  = 0.012moldm⁻³

Answer:
Nobelium is made by the bombardment of curium (Cm) with carbon nuclei. Its most stable isotope, 259No, has a half-life of 58 minutes and decays to Fermium (255Fm) through alpha decay or to Mendelevium (259Md) through electron capture.

Abiotic factors, also called abiotic components, are non-living parts of the environment which affects the living organisms and their function in the ecosystem. I think the correct answer is A. Wind factor is the only non-living part from the choices.
        
                    
             
        
        
        
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
        
                    
             
        
        
        
Answer:
lithium=atomic no.=3
Explanation:
-1 charge on lithium means one electron has added to it .Thus,
   Li-1=no. of electrons=3+1=4
