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
Mexico, because it is closer to the equator and it has more deserts, as Canada is known for being cold and snowy.

Answer:
26.9 L.
Explanation:
Hello there!
In this case, since the ideal gas equation is able to provide us the volume of neon in 1.2 moles by considering the STP conditions (1.00 atm and 273.15 K) via its mathematical definition:
![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
We first need to solve for V in the aforementioned equation:
![V=\frac{nRT}{P}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7BnRT%7D%7BP%7D)
So we plug in to obtain:
![V=\frac{1.2mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1.00atm}\\\\V=26.9L](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1.2mol%2A0.08206%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2A273.15K%7D%7B1.00atm%7D%5C%5C%5C%5CV%3D26.9L)
