Chemistry , they are all together

Question

uestion 4a (6 Points; 2 Points Each)

Balance the following equations

 

Ca(AlO2)2(s) + HCl (aq) ---> AlCl3(aq) + CaCl2(aq) + H2O(ℓ)

 

 

 

 

C6H6 + H2O2 ---> CO2 + H2O

 

 

 

 

AlCl3(s) + Ca3N2(s) ---> AlN(s) + CaCl2(s)

 

 

 

Question 4b (9 Points; 3 Points each)

 

1. How many moles is 270 (g) of Na2SO4?

 

 

 

 

 

 

 

2. How many molecules of ethane (C2H4) in 4.3 moles of ethane?

 

 

 

 

 

 

 

3. How many atoms of C in 600 (g) of C12H22O11?

 

Answer 1

Ca(AlO₂)₂(s) + 8HCl (aq) ---> 2AlCl₃(aq) + CaCl₂(aq) + 4H₂O(ℓ)

 

2C₆H₆ + 15O₂ ---> 12CO₂ + 6H₂O (assuming this is the reaction you meant to submit)

 

2AlCl₃(s) + Ca₃N₂(s) ---> 2AlN(s) + 3CaCl₂(s)

You try the others using this information.

moles Na2SO4 = 270 g x 1 mol / molar mass Na2SO4

4.3 moles ethane x 6.02x1023 molecules / mole = molecules of ethane

600 g C12H22O11 x 1 mol / molar mass C12H22O11 x 6.02x1023 molecules/mole x 6 C atoms/molecule
