This balanced equation shows us the ratios of reactants and products, so for every 3 oxygen molecules, we see that 4 iron atoms react as well. The answer is 4.
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change. A chemical reaction is a mechanism that takes place when two or more molecules interact to produce new products. A reaction between two atoms or ions or molecules may take place and a new bond is formed and no atom is destroyed or created, but reactants form a new substance.
True ^_^
50.00ml*(10^-3L/ml)*(3.91moles/L) = 0.196 mol
Answer:
1.58 102 mol
Explanation:
I just looked it up on Quizlet.
Answer:-
Ca-Cl
Explanation:-
The more the difference in electronegativity more the polar bond.
In case of Ca-Cl the difference = 3.16 - 1= 2.16
It is more than all the other combinations given.
Hence Ca-Cl is the most polar covalent bond.
