Answer:
The correct answer is A all chemical bonds are hard to break
Explanation:
The minimum amount of energy that is required to break a chemical bond is known as bond energy.
Different amount of energy is required to break different bonds. For example High amount of energy is required to break covalent bond whereas a low amount of energy is required to break non covalent bonds such as hydrogen bond, hydrophobic interaction,van der waal interaction etc.
Answer:
0.925 mole
Explanation:
From the question given, the following were obtained:
Volume = 1.0L
Molarity = 0.925 M
Number of mole of Nickel (II) chloride =?
Molarity is simply defined as the mole of solute per unit litre of the solution.
It is represented mathematically as:
Molarity = mole /Volume
With the above equation, we can easily find the mole of Nickel (II) chloride present in the solution as follow:
Molarity = mole /Volume
0.925 = mole / 1
Mole = 0.925 x 1
Mole of Nickel (II) chloride = 0.925 mole
The correct answer is Iron and magnesium
