The only true answer is A.
products are on the right side of the reaction
products and reactants don't necessarily have same physical or chemical properties
It is the reactants that <span>are the atoms, molecules, or compounds that participate in the reaction.</span>
The letter only has reflection symmetry, if you rotated it it would look the same.
<span>One atom of silicon can properly be combined in a compound with two atoms of oxygen.</span>
Explanation:
A compound is defined as follows.
- Compounds are pure substance.
- The atoms bonded in a compound are in specific proportion.
- A compound is formed by chemical combination.
- For a compound, melting point and boiling point is defined.
A mixture is defined as follows.
- Mixtures are impure substance.
- The bonded atoms in a mixture are in any proportion.
- A mixture is formed by physical combination.
- For a mixture, melting point and boiling point is not defined.
On changing the amount of one substance will affect the formation of compound as a compound requires atoms to be bonded in a specific proportion. Whereas changing the amount of one substance will not affect the formation of mixtures as atoms can be bonded in any proportion in a mixture.
