Atomic radius of copper atom (r)= 128 pm
volume of sphere = 4/3 * pi * r^3 = 4/3 * 3.14 * 128^3
volume = 8780076.373 pm^3
Answer: An ionic bond is a bond that forms between ions with opposite charges.
Explanation:
A chemical bond formed by the transfer of electrons from one atom to another is called an ionic bond.
For example, sodium has electronic distribution as 2, 8, 1 and chlorine has electronic distribution as 2, 8, 7.
In order to attain stability, sodium needs to lose 1 electron and chlorine needs to gain one electron. Therefore, sodium will transfer its one valence electron (forming ion) to chlorine atom (forming ion) which leads to the formation of NaCl compound.
Thus, we can conclude that an ionic bond is a bond that forms between ions with opposite charges.
Answer:
increase the rate of a reaction without being consumed by the reaction
Explanation:
- Enzymes are biochemical catalysts that increase the rate of chemical reactions.
- They increase the rate of a chemical reaction without being consumed by the reaction.
- Enzymes increase the rate of chemical reactions by decreasing the activation energy of the reactants.
- Catalysts such as enzymes do not affect the free energy change of a chemical reaction (delta G). Therefore, delta G for a catalyzed and non-catalyzed reaction is equal.
Complete question
The complete question is shown on the first uploaded image
Answer:
The value is
Explanation:
From the question we are told that
The mass of NaOH is
In the question DI (stands for de-ionized water )
So the number of moles of NaOH present in the given mass is
Here Z is the molar mass of NaOH with value
So
Given that the volume of the flask is V = 1 L then we can evaluated the concentration as
=>
=>
