Answer:
C.) new substances that are present at the end of a reaction.
Explanation:
In a chemical reaction, substances are combined to form other substances. The substances, in a chemical reaction, that are combined or used up are called REACTANTS while those substances that are synthesised newly at the end of the reaction are called PRODUCTS.
For example, in the chemical reaction between carbon dioxide and water in photosynthesis to form glucose and oxygen as follows:
6CO2 + 6H2O --> C6H12O6 + 602
CO2 and H2O are the REACTANTS because they are the combined substances.
C6H12O6 and 02 are the PRODUCTS because they are new substances present at the end of the reaction.
Halogen are the most reactive due to their electronic configuration
Sodium and potassium are most likely to have similar physical and also chemical properties. They are in the same family called Alkali metals. Both will have the same valence electrons and are both very reactive.
Answer:
The answer is 1722 e⁻
Explanation:
Let's make a rule of three:
9.708×10⁻³¹ kg is the mass of 1 e⁻
1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?
1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg
The answer is 1722 e⁻
