Explanation:
In this reaction, the reactants are Li and N2. The product is Li3N
So we have;
Li + N2 → Li3N
Upon balancing, we have;
6Li + N2 → 2 Li3N
The sum of the coefficients is 6 + 1 + 2 = 9
Sn + 4 HNO₃ → SnO₂ + 4 NO₂ + 2 H₂O
Heating was required to get rid of the H₂O. When all moisture is gone,
you weigh the sample. After which, you further heat it to get ride of the
oxygen. By doing this, you would know the individual mass of each
element. Then, you can solve for the empirical formula of the oxide of
tin.
Hope this helps best of luck :)
Answer:
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Explanation:
In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Spontaneous is no spontaneous
