C2H2O4 C2HO4- + H+
0.175 - x x x + y
C2HO4- c2o42– + H+
x - y y x + y
K2 = (y) (x +y) / (x-y)
As, y << x
So, K2 = (y) (x) / (x)
K2 = y =6.1 × 10^–5
Hence, concentration of (c2o42–) 6.1 × 10^–5 M
16g.
mol=gram/molar mass
4.00mol=g/4.0 molar mass of Helium
4mol*4g/mol= 16grams
Each discrete distance orbit from the nucleus corresponds to a certain energy level. The electron which rotates in the lowest orbit has lowest energy level and in the outermost orbit.
Explanation:
Carbon is a non-metal then carbon dioxide is a non-metal oxide. Non-metal oxides reacts with water to produce acids.
non-metal oxide + water ----> acid
carbon dioxide + water ----> carbonic acid
CO₂ + H₂O ---> H₂CO₃
Answer: H₂CO₃ (H2CO3)
It is to find an unbiased group of people unrelated to the event and it is a way for even the least patriotic citizens to serve their country. It also means there IS A JURY, if there wasn't; then it would come done to the whims of the judge.
