Soda lime is a mixture primarily consisting of calcium hydroxide which is used to remove carbon dioxide gas ( CO2) from the surrounding medium.
The reaction of calcium hydroxide with carbon dioxide produces a white insoluble precipitate of calcium carbonate.
The chemical equation for the reaction is given below.
From the above equation we can see that the mole ratio of Ca(OH)₂ and CaCO₃ is 1:1 . This can be used as a conversion factor to find moles of CaCO₃ formed during the reaction
![2mol[Ca(OH)2] * \frac{1mol[CaCO3]}{1mol[Ca(OH)2]} = 2 mol [CaCO3]](https://tex.z-dn.net/?f=%202mol%5BCa%28OH%292%5D%20%2A%20%5Cfrac%7B1mol%5BCaCO3%5D%7D%7B1mol%5BCa%28OH%292%5D%7D%20%3D%202%20mol%20%5BCaCO3%5D%20)
Using molar mass of CaCO3 ( MW = 100.1 g/mol) we can convert moles of CaCO3 to grams.
![2mol[CaCO3] * \frac{100.1g[CaCO3]}{1mol[CaCO3]} = 200.2g[CaCO3]](https://tex.z-dn.net/?f=%202mol%5BCaCO3%5D%20%2A%20%5Cfrac%7B100.1g%5BCaCO3%5D%7D%7B1mol%5BCaCO3%5D%7D%20%3D%20200.2g%5BCaCO3%5D%20)
200.2 grams of the precipitate will be produced.
Answer:
When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.

The question is: To neutralize 20ml of 0.1M HCl solution, 10ml of NaOH solution of concentration x mol/l is required. What is the value of x?
Answer: The value of x is 0.2 M.
Explanation:
Given: 
= 20 mL, 
= 0.1 M
= 10 mL, 
= x
Formula used is as follows.
Thus, we can conclude that the value of x is 0.2 M.
