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.
There are six (6) bonding electrons are in the lewis structure of carbon monoxide (CO).
In Lewis structure, there are ten (10) valence electrons of Carbon monoxide (CO). For lewis structure we need a triple bond between carbon and oxygen, so when electrons made a triple bond it means there is six bonding electrons in lewis structure of carbon monoxide.
Answer:
Penta hydrogen chlorine
Explanation:
they are ploy atomic elements
Answer:
A. Adding another bulb will make the two of them light a little less brighter since the electrical flow is divided into two making them work.
B. There is a possibility that the flow of electricity maybe little due to the thickness of the wire. There could also be a rise in the temperature of the cell and the bulb.
C. The Bulb will shine brighter because of the extra power or electricity provided! Also, if the voltage is too much, expect the bulb to burn out or sadly, explode.
BTW GOODLUCK!!
