Answer:
90g of Ca(OH)2
Explanation:
2HCl + Ca(OH)2 —> CaCl2 + 2H20
Molar Mass of Ca(OH)2 = 40 + 2( 16 + 1) = 40 + 2(17) = 40 + 34 = 74g/mol
Molar Mass of CaCl2 = 40 + (2 x 3.5) = 40 + 71 = 111g/mol
From the equation,
74g of Ca(OH)2 produced 111g of CaCl2.
Therefore, Xg of Ca(OH)2 will produce 135g of CaCl2 i.e
Xg of Ca(OH)2 = (74 x 135) / 111 = 90g.
Therefore, 90g of Ca(OH)2 are required to produce 135g of CaCl2
Answer:
sodium and chlorine.......
The concentration is 5 g/L.
Concentration = mass/volume = 10 g/2 L = 5 g/L

<h3>What is functional group?</h3>
Functional group is the specific group which is present in an organic compound gives information about the properties of that compound.
- In 1,2-propanediol compound hydroxyl functional group is present on the 1st and 2nd position.
- In Ethyl methyl ether, ether functional group is present.
- In Dichloromethane, two atoms of chlorine groups are present.
Hence, structure of the given compounds are shown in the below image.
