Taking into account the reaction stoichiometry, 2 moles of CaO are required to react with 2 moles of Ca(OH)₂.
<h3>Reaction stoichiometry</h3>
In first place, the balanced reaction is:
CaO + H₂O → Ca(OH)₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- CaO: 1 mole
- H₂O: 1 mole
- Ca(OH)₂: 1 mole
<h3>Moles of CaO required</h3>
The following rule of three can be applied: If by stoichiometric reaction 1 mole of Ca(OH)₂ is produced by 1 mole of CaO, 2 moles of Ca(OH)₂ are produced by how many moles of CaO?

moles of CaO= 2 moles
Finally, 2 moles of CaO are required to react with 2 moles of Ca(OH)₂.

Answer:
They are in a periodic table
Answer:
Explanation:
Kindly answer the way I have written.
Answer:
The acceleration of the ball when it begins to move is 200 m/s²
Explanation:
The given parameters are;
The mass of the metal ball, m = 0.025 kg
The force exerted by the magnet on the ball, F = 5 N
From Newton's second law, F = m × a
Where;
a = The acceleration of the ball
Therefore, by substitution, we have;
5 = 0.025 × a
a = 5/0.025 = 200 m/s²
The acceleration of the ball when it begins to move = 200 m/s²
