that’s the ones I put and I got a 100% on my test just now
Answer: 50. 4g
Explanation:
First calculate number of moles of aluminium in 38.8g
Moles = 38.8g/ 26.982mol/g
= 1.44mol
By looking at the balance equation you can see that 4 moles of aluminium produce 2 moles of aluminium oxide.
4 = 2
1.4 = x
Find the value of x
x= (1.4×2)/4= 0.72 mol
0.72 moles of aluminium oxide are produced from 38.8g of aluminium
Now find the mass of aluminium produced.
Mass = moles × molar mass
= 0.72mol × 69.93 mol/g
= 50.4g
Because it's oil and oil always sits on top of water
the movement of air parallel to earth’s surface is called wind
Answer:
H2CO3,HCl
Explanation:
the rest are not acids but I arrange the acids based on their number of hydrogen
