Answer:
One is hands on and one is watching
Explanation:
I just know my science
1.09 Liters
The total volume of the solution formed is 1.093 L
We know that,
Ca(OH)2 = 74 g/mole
n = 55/74 = 0.743 mole
M = n/V
where,
M = mass of the solution
n = number of moles
V = Volume of solution
0.680 = 0.743 / V
V = 0.743/0.680
= 1.093 L
= 1093 ml
Therefore, the total volume of the solution formed is 1.093 L
<h3>What is molarity?</h3>
- The amount of a substance in a specific volume of solution is known as its molarity (M).
- The number of moles of a solute per liter of a solution is known as molarity.
- The molar concentration of a solution is another name for molarity.
<h3>What is the molarity unit?</h3>
- Molarity is measured in mol/L.
- The molarity, which is given as moles/liter, is the quantity of moles of solute per liter of the solution.
<h3>Example of molarity:</h3>
- The moles of solute per liter of solution is measured as molarity.
- For instance, when table salt is dissolved in water, water serves as both the solution and the solute.
- Sodium chloride weights 58.44 grams per mole.
- One molar solution, or 1M, is created by dissolving 58.44 grams of sodium chloride in one liter of water.

Your answer is 4 protons 4 electrons and 5 neutrons
Answer & Explanation:
Los electrones externos se encuentran más lejos del núcleo. El número de electrones en la capa más externa (electrones de valencia) de un átomo en particular determina su reactividad (tendencia) a formar enlaces químicos con otros átomos.
Los electrones internos son los más cercanos al núcleo. Protegen los electrones de valencia del núcleo, reduciendo la carga nuclear efectiva.
