Gabriel Fahrenheit invented the thermometer
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.
