35 protons 35 electrons and 45 nutrons
Answer:
Ammonia > Urea > Ammonium nitrate > Ammonium sulphate
Explanation:
Percentage by mass of nitrogen in NH3:
Molar mass of NH3= 17 g/mol
Hence % by mass = 14/17 × 100 = 82.35%
% by mass of NH4NO3
Molar mass of NH4NO3 = 80.043 g/mol
Hence; 28/80.043 × 100 = 34.98%
% by mass of (NH4)2SO4;
Molar mass of (NH4)2SO4= 132.14 g/mol
Hence; 28/132.14 × 100 = 21.19%
% by mass of CH4N2O
Molar mass of urea = 60.0553 g/mol
Hence 28/60.0553 × 100 = 46.62%
the effects are: temperature rises, water shortages, and increased fire threats
Answer: Clean Air Act
Explanation: The Clean Air Act of 1963 was one of the first and most influential modern environmental laws designed to control Air pollution at a National level.
The statement in the question above is one of the bold direct statements of the Clean Act Law.
Since it's C2, then it must be two Carbon atoms. Think of it this way; there are two atoms of Hydrogen in a water molecule, so we now have H2O.
