Atomic number The atomic number of each element is different than other Elements.
Answer :
X = ![Al_2(SO_4)_3](https://tex.z-dn.net/?f=Al_2%28SO_4%29_3)
Y = ![H_2O](https://tex.z-dn.net/?f=H_2O)
Explanation :
Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The given chemical equation is:
![2Al(OH)_3+3H_2SO_4\rightarrow X+6Y](https://tex.z-dn.net/?f=2Al%28OH%29_3%2B3H_2SO_4%5Crightarrow%20X%2B6Y)
As we know that when aluminum hydroxide react with sulfuric acid then it gives aluminum sulfate and water as product.
The balanced chemical reaction will be:
![2Al(OH)_3+3H_2SO_4\rightarrow Al_2(SO_4)_3+6H_2O](https://tex.z-dn.net/?f=2Al%28OH%29_3%2B3H_2SO_4%5Crightarrow%20Al_2%28SO_4%29_3%2B6H_2O)
Thus, X is
and Y is ![H_2O](https://tex.z-dn.net/?f=H_2O)

Hello there!
In this case, for this gas stoichiometry problem, we first need to compute the moles of carbon dioxide via stoichiometry and the molar mass of starting calcium carbonate:
![3.56gCaCO_3*\frac{1molCaCO_3}{100gCaCO_3} *\frac{1molCO_2}{1molCaCO_3} =0.0356molCO_2](https://tex.z-dn.net/?f=3.56gCaCO_3%2A%5Cfrac%7B1molCaCO_3%7D%7B100gCaCO_3%7D%20%2A%5Cfrac%7B1molCO_2%7D%7B1molCaCO_3%7D%20%3D0.0356molCO_2)
Next, we use the ideal gas equation for computing the volume, by bearing to mind that the STP conditions stand for a pressure of 1 atm and a temperature of 273.15 K:
![PV=nRT\\\\V=\frac{nRT}{P}\\\\V=\frac{0.0356mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm} \\\\V=0.798L](https://tex.z-dn.net/?f=PV%3DnRT%5C%5C%5C%5CV%3D%5Cfrac%7BnRT%7D%7BP%7D%5C%5C%5C%5CV%3D%5Cfrac%7B0.0356mol%2A0.08206%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2A273.15K%7D%7B1atm%7D%20%5C%5C%5C%5CV%3D0.798L)
