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.

Explanation:
Answer: YES
Explanation:
POLAR BONDS will form.
A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.
Answer:
<h3>The answer is 150 kPa</h3>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we are finding the new pressure
From the question we have
We have the final answer as
<h3>150 kPa</h3>
Hope this helps you
Answer:
the heat source must be greater than 100°C
the water must be permitted to evaporate quickly
the system must be sealed and become pressurized above atmospheric pressure
the vapor pressure must be kept below 760 mmHg
Explanation:
A superheated water is a dry form of steam in which hydrogen bonds that strongly binds the molecules of water has been overcome.
Superheated water finds application in a wide range of places. For example they are used for sterilization of clinical equipment.
- To produce steam or superheated water, the temperature of the source must be greater than the boiling temperature and less than the critical temperature at 374°C.
- Since superheated water is steam and steam is water in gaseous form. The water must be made to evaporate more quickly than it should condense back.
- High pressure and sealing the system helps to produce superheated water very fast.
- If the pressure between the vapor is kept low, water will boil faster.
