Answer: 111g S
Explanation:
SO2 you have = 665 g
SO2 molar mass = 64.066 g/mol
S molar mass = 32.065 g/mol
Answer: The number of N atoms in 137.0 g of N2O3 21.67 x 10∧23 atoms.
Explanation:
- We must obtain the number of moles of the compound: (n = mass/molar mass), mass = 137.0 g and molar mass of N2O3 = 76.01 g/mol.
- n = (137.0 g)/ (76.01 g/mol) = 1.80 mol.
- It is necessary to determine the number of molecules of this sample.
- Every mole contains Avagadro's number (6.02 x 10^23) of molecules.
- The number of molecules = (6.02 x 10^23)(1.80) = 10.84 x 10∧23 molecules.
- Every molecule of N2O3 contain 2 atoms of N.
- The number of N atoms in 137.0 g of N2O3 = (10.84 x 10∧23 molecule) (2 atoms) = 21.67 x 10∧23 atoms.
Answer:
When baking soda or sodium Bicarbonate (NaHCo3) reacts with water carbonic acid is formed . The reaction is exothermic (so yes releases energy) that is heat (type of energy released) and Carbonic acid are produced. Carbonic acid is unstable so breaks up into carbon dioxide (which is the fizzy gas you see) and water forms.
