Answer is: There are more reactants and one product of the reaction. The reactants may be elements or compounds. The product is always a compound.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
For example, balanced chemical reaction: Ba + F₂ → BaF₂.
In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
Second chemical reaction: CaO(s) + H₂O(l) → Ca(OH)₂(aq).
One molecule is produced from two molecules.
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.
hi
1 mile is 1 609 meters. (rounded).
As there is 100 centimeters in a meter, then
1 mile is 160 900 centimeter.
Then 1.5 miles , is 1 mile + one half so :
160 900 + 160 900 /2 = 160 900 + 80 450
= 241 350
1.5 mile is 241 350 centimeters.
please note that the value of a mile was rounded.
Answer:
it is already balanced bro
