Explanation:
In nitrate ion that is ,have negative charge on overall ion. Negative charge on the one oxygen atom is de-localized to other oxygen atoms present in the molecule of a nitrate ion. Due to this resonance nitrate ions get stabilized.
For resonance structures for the nitrate ion, refer to image attached.
Answer:
Blank 1 - 2
Blank 2 - 4
Blank 3 - 3
Explanation:
The unbalanced chemical equation given in the question is as follows:
Au2O3 → Au + O2
To balance a chemical equation, the number of atoms of each element on both sides of the equation (reactants and product) must be the same. Based on this explanation, the balanced chemical equation is as follows:
2Au2O3 → 4Au + 3O2
- 4 atoms of gold (Au) on both sides
- 6 atoms of oxygen on both sides
Hence, based on the question, blank 1, 2 and 3 are 2, 4 and 3 respectively.
I think the best example of rotational motion is :
The wheel spins as long as the hamster keeps running
Rotational motion refer to a rotation movement in which the main axis point stays the same
hope this helps
I'm not quiet sure...possibly an ionic bond.
